The present disclosure relates generally to improved hydraulic fracturing missiles and related systems, apparatus and methods.
Hydraulic fracturing operations typically involve the use of a hydraulic fracturing missile (“frac missile”), sometimes referred to as a frac pump output header. The frac missile is often described as a flow control unit used in the pressurization of fluid employed in hydraulic fracturing. The frac fluid will normally enter the frac missile at low pressure from a frac blender or other source(s), be directed to one or more frac pumps (typically on trucks) for pressurization, returned to the frac missile and then directed to the well(s) or other equipment.
Frac missiles typically includes a (i) low-pressure (LP) side having one or more LP fluid flow lines for receiving frac fluid from the blender(s) or other source and directing it to the frac pumps and (ii) a high-pressure (HP) side having one or more HP fluid flow lines for receiving the frac fluid from the pumps and directing it to the well(s) or other destination(s). The LP and HP lines often extend across multiple support structures, or skids, and are made up of a series of components coupled together. For example, the LP line typically includes a blender manifold having ports, or inlets, for coupling to the frac blender(s) and a series of outlets for coupling to the frac pumps. The HP line usually also includes inlets and outlets.
Many known presently available frac missiles are believed to have one or more disadvantages. For example, components included in the LP lines are often formed or coupled together using welds. Welded components and connections in the LP line can have or cause any number of problems. For example, the welds can be subject to weakening, degradation and failure (e.g., leakage, stress cracking, blistering, breakage) due to contact with acid, hydrogen sulfide or other chemicals or substances that may be present in fluid flowing therethrough or in the area of operation. For another example, the abrasive nature of frac proppant, or sand, in the frac fluid traveling under pressure (e.g., 200 psi or more) through the LP line can wear down, penetrate (e.g., with pin holes) or wash out the welds, causing premature failure of the LP line. In fact, welds can be the weakest points along the LP line and often the first part of LP line to leak, fail or require repair. Thus the life of the LP line and its components and the frac missile is limited when welds are used.
For a further example, when it is desirable or necessary to replace, change, reconfigure or modify weld-connected components of the LP line(s), or to patch or repair a compromised weld, operations will typically need to be shut down for an extended period, the work area needs to be inspected and cleared of gas and other ignitable sources and made safe for welding, hot permits for welding on the site may need to be obtained and one or more welders brought in. Often, an LP line with welds requires rewelding again and again, causing substantial down time and expense.
For yet another example, many known frac missiles include only a single blender manifold, limiting the number of inlets or ports to the LP line(s). For still another example, the blender manifolds (e.g., a rounded pipe) on many presently known frac missiles have limited space that allows only a fixed number of ports, or inlets, limiting the versatility and use of the frac missile. Often, the inlets are welded to the blender manifold, requiring the same time consuming, costly, burdensome process and limitations described above in order to add or replace inlets, provide different sized inlets and the like. Thus, many known conventional blender manifolds cannot be easily modified to change out or add inlets to the LP line(s). For another example, conventional frac missiles usually require a valve associated with the LP side to be able to separate flow of frac slurry and clean water, when desired. The necessity of requiring a valve can lead to problems, such as the valve washing out or malfunctioning. For yet a further example, the outlets on the LP line are often welded thereto, requiring the same process and limitations as above to provide different sized outlets, add or replace outlets and the like.
For still another example, various components on the frac missile may be unique or arranged in a unique manner, not be interchangeable and, consequently, cannot be easily interchanged or switched out with an on-hand replacement. In many cases, to change the length of a conventional LP line or add inlets or outlets thereto can require cutting and welding to extend or reduce pipe. Likewise, the different skids used in a conventional frac missile are often unique, differing from one another and not being interchangeable, requiring substantial time and effort to create a replacement or convert any of the skids for use at another location in the frac missile.
Many of the same or similar disadvantages and limitations as described above may exist for the HP lines currently used on various conventional frac missiles.
Accordingly, there exists a need for improved hydraulic fracturing missiles and related systems, apparatus and methods.
It should be understood that the above-described disadvantages, limitations, features, capabilities, examples, advantages and other details are provided for illustrative purposes only and are not intended to limit the scope or subject matter of this disclosure or the appended claims. Thus, none of the appended claims should be limited by the above discussion or construed to address, include or exclude each or any of the above-cited disadvantages, limitations, features, capabilities, examples, details or advantages merely because of their mention above.

Accordingly, the present disclosure includes features and advantages which are believed to enable it to advance hydraulic fracturing systems, apparatus and methods. Characteristics and advantages of the present disclosure described above and additional features and benefits will be readily apparent to those skilled in the art upon consideration of the following detailed description of various embodiments and referring to the accompanying drawings.
The following figures are part of the present specification, included to demonstrate certain aspects of various embodiments of this disclosure and referenced in the detailed description herein:
Characteristics and advantages of the present disclosure and additional features and benefits will be readily apparent to those skilled in the art upon consideration of the following detailed description of exemplary embodiments and referring to the accompanying figures. It should be understood that the description herein and appended drawings are of exemplary embodiments and not intended to limit the claims of this patent (or any patent or patent application related hereto). On the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of this disclosure and the claims. Many changes may be made to the particular embodiments and details disclosed herein without departing from such spirit and scope.
In showing and describing preferred embodiments in the appended figures, common or similar components, features and elements are referenced with like or identical reference numerals or are apparent from the figures and/or the description, claims and other parts of this patent. The figures are not necessarily to scale and certain features and certain views of the figures may be shown exaggerated in scale or in schematic in the interest of clarity and conciseness.
When reference numbers are followed by a lowercase letter (e.g., first and second connectors 117A, 117B), they are each the same type of component or item (e.g., a connector 117) having the same features, but having a different location, use or other characteristic(s). In some instances, the drawings or discussion herein may include only reference numerals followed by lowercase letters (e.g., first and second connectors 117A, 117B), without any separate reference to the primary feature alone (e.g., connector 117). In those cases, it should be presumed that the referenced items (e.g., first and second connectors 117A, 117B) are examples of the primary feature (e.g., connector 117), even though the primary feature is not referenced separately.
As used herein and throughout various portions (and headings) of this patent (including the claims), the terms “invention”, “present invention” and variations thereof are not intended to mean every possible embodiment encompassed by this disclosure or any particular claim(s). Thus, the subject matter of each such reference should not be considered as necessary for, or part of, every embodiment hereof or of any particular claim(s) merely because of such reference.
The terms “including” and “comprising” are used herein and in the appended claims in an open-ended fashion and thus should be interpreted to mean “including, but not limited to”. Reference herein and in the appended claims to components, features, aspects, etc. in a singular tense does not necessarily limit the present disclosure or appended claims to only one such component, feature or aspect, but should be interpreted generally to mean one or more, except and only to the extent as may be expressly specified otherwise herein or in any particular claims hereof and only for such specific references or claims and other claims depending therefrom. Accordingly, the use of “a”, “an” or “the” before a noun refers to and should be interpreted to mean “one or more”, except and only to the extent as may be expressly specified otherwise. For example, a recitation in the description or claims herein of “a connector coupled between X and Y” should be construed to mean that “one or more connectors is coupled between X and Y”, unless a different construction is expressly provided. Also, the use of “(s)” in reference to an item, aspect, component, feature, action, etc. (e.g., “surface(s)”) should be construed to mean “at least one”.
The use of “or” herein provides alternate possibilities, only one of which may be present. All such possibilities do not need to be available. For example, if an embodiment of a component is described as “having a collar or coupling”, it may include only one or more collars, only one or more couplings or at least one of each. The use of “or” herein thus does not require all of the possibilities be available, just any one or more of them. Similarly, the use of “and/or” herein provides for numerous possibilities, only one of which may be present. All the possibilities do not need to be available—only any one of them. For example, if an embodiment of a component is described as “having a collar and/or a coupling”, it may include only one or more collars, only one or more couplings or at least one of each. Thus, the use of “and/or” herein does not require all the possibilities, just any one or more of them.
The phrase “at least one among” as used herein generally has the same meaning as “and/or”. For example, if an embodiment of a component is described as “having at least one among a collar, coupling and connector”, it may include only one or more collars, only one or more couplings, only one or more connectors or any combination thereof. Thus, the use of “at least one among” herein and in any appended claims does not require all those possibilities to be available, just any one or more of them.
The terms “for example”, “exemplary”, “e.g.”, “such as” and variations thereof are used herein to provide one or more possible examples of the referenced item, feature, detail, circumstance, etc. that may be present, possible or occur in some instances. Such examples are not exclusive, not the only possibilities and not required for every embodiment or any claims, except and only to the extent as may be expressly specified otherwise herein or in any particular claims hereof and only for such specific references or claims and other claims depending therefrom.
Certain terms are used herein and in the appended claims to refer to particular features and components. As one skilled in the art will appreciate, different persons may refer to a feature or component by different names and this document does not intend to distinguish between components and features that differ in name but not function. The following numerals are used herein for referencing the exemplary features, or components, of various embodiments associated therewith below, but are not intended to and should not limit the scope of this patent or any appended claims, except and only to the extent as may be expressly specified otherwise. These terms, and others used in this patent, are believed to have a sufficiently well-understood and definite meaning to persons of ordinary skill in the relevant art as the name for structure:
As used throughout and in all parts of this patent, the following terms have the following meanings, except and only to the extent as may be expressly specified otherwise:
The terms “connector”, “coupling”, “fastener” and the like, and variations thereof, are used interchangeably to mean and include any suitable form of hardware or configuration of components that causes the referenced items to be connected together. The present disclosure and appended claims are thus not limited to the specific types of couplings and connectors described herein or shown in the appended drawings, except and only to the extent as may be expressly specified otherwise herein or in any particular claims hereof and only for such specific references or claims and other claims depending therefrom.
The terms “coupled”, “connected”, “engaged” and the like, and variations thereof refer to and include either an indirect or direct connection or engagement. Thus, if a first device couples to a second device, that connection may be through a direct connection, or through an indirect connection via other devices and/or connections, except and only to the extent as may be expressly specified otherwise herein or in a particular claim hereof, and only for such reference or claim(s) and any claim(s) depending therefrom.
The terms “elongated” and variations thereof as used herein mean and refer to an item having an overall length (during the intended use of the item) that is greater than its average width.
The terms “fluid” and variations thereof refer to and include one or more liquids, gas and/or solids, including, without limitation, foam, gel, solvent, chemicals, lubricant, materials, particles, proppant, slurry or a combination thereof. The form, components, properties and any other characteristics of any fluid that may be mentioned herein is not limiting upon the present disclosure or appended claims, except and only to the extent as may be expressly specified otherwise herein or in any particular claims hereof and only for such specific references or claims and other claims depending therefrom.
The terms “high-pressure”, “HP”, “discharge” and variations thereof are used interchangeably herein to refer generally to use in connection with the discharge or high pressure side of a hydraulic fracturing missile or system, which may, for example, accommmodate fluid or slurry flow at pressures of up to approximately 15,000-20,000 psi (or more or less), but which pressure may vary depending upon the type of equipment, application, environment or circumstances of use, other variables or a combination thereof. The present disclosure and appended claims should not be limited by this definition or any other meaning of high pressure or any actual amount or ranges of pressure, except and only to the extent as may be expressly specified otherwise herein or in any particular claims hereof and only for such specific references or claims and other claims depending therefrom.
The terms “low-pressure”, “LP”, “suction” and variations thereof are used interchangeably herein to refer generally to use in connection with the suction or low pressure side of a hydraulic fracturing missile or system, which may, for example, accommodate fluid or slurry flow at pressures of no more than approximately 285-1,000 psi (or more or less), but which pressure may vary depending upon the type of equipment, application, environment or circumstances of use, other variables or a combination thereof. The present disclosure and appended claims should not be limited by this definition or any other meaning of low pressure or any actual amount or ranges of pressure, except and only to the extent as may be expressly specified otherwise herein or in any particular claims hereof and only for such specific references or claims and other claims depending therefrom.
The terms “minimal” and variations thereof generally mean no more than 5-10%.
The terms “party”, “user”, “entity”, “person”, “operator”, “manpower”, “labor” and the like refer to and include one or more humans, legal entities, virtual entities, beings and avatars, robots and robotic components, artificial intelligence-driven components/circuitry, other entities, components and the like or the effort thereof.
The terms “rigidly coupled” and variations thereof mean connected together in a manner that is intended not to allow any, or more than an insubstantial, tolerable, nominal or minimal amount of relative movement therebetween as may be expected during typical or normal operations. In other words, if components A and B are rigidly coupled together, they are not movable relative to one another (more than an insubstantial, tolerable, nominal or minimal amount) during typical or expected operations.
The terms “spool” and variations thereof refer to a section of a conduit (e.g., pipe, tube) designed for and capable of use in an LP or HP line of a hydraulic fracturing manifold or related component. A spool need not be flanged or hubbed, even though various embodiments herein include flanges or hubs.
The terms “substantial” and variations will depend upon the type of component, equipment, application, circumstances of use, other variables or a combination thereof, as are and become further known to persons of ordinary skill in the relevant art. In some instances, such as when used to describe the amount or degree of something (e.g., “reduces a substantial volume of fluid”), substantial may mean by at least approximately 75% and insubstantial being no more than about 25%.
The terms “universal”, “modular” and variations thereof are used interchangeably herein to refer generally to a component or item having a standard construction or standardized units, features or dimensions for ease, flexibility and versatility in its use, interchangeability, replacement, positioning, interconnection, deployment, removal, any other purposes or a combination thereof. Multiple of the same type, model or version of universal or modular component may be identical and interchangeable and, in some cases, reversible or non-direction-specific (e.g., to allow fluid flow therethrough in either direction). A universal or modular component may be a stand-alone item designed to be easily removed and replaced (e.g., with mechanical connectors), useful at different locations in a component or assembly (e.g., frac missile, missile skid, LP line, HP line), reversible or non-direction-specific (e.g., to allow fluid flow therethrough in either direction) or a combination thereof.
It should be noted that any of the above terms may be further explained, defined, expanded or limited below or in other parts of this disclosure. Further, the above list of terms is not all inclusive and other terms may be defined, used or explained below or in other sections of this patent.
Referring initially to
The exemplary LP line(s) 20 and HP line(s) 22 could be arranged in, or on, the missile skid 10 in any suitable manner. Each illustrated LP line 20 and HP line 22 is shown extending generally longitudinally on the support structure 50 and can thus be characterized as having a respective longitudinal axis 72, 74 (e.g.,
The LP and HP lines 20, 22 may have any suitable purpose(s). For example, one or more LP lines 20 may be used to fluidly connect one or more frac blenders 60 with one or more frac pumps 70 (e.g., on pump trucks or trailers), while the HP line(s) 22 may be used to fluidly couple the frac pump(s) 70 with one or more hydrocarbon wells 76 (or related components). In many applications, the frac pumps 70 may suck, or draw in fluid (e.g., frac-slurry with proppant, water, chemicals, etc.) from the frac blender 60 through one or more exemplary LP lines 20, then pump the slurry at a higher pressure through one or more HP lines 22 to the well(s) 76. This exemplary sequence is shown in
Referring again to
The exemplary HP line 22 includes one or more (e.g., six) HP inlets 64 for fluidly coupling the frac pump(s) 70 (or other equipment) to the HP line 22, along with one or more HP outlets 66 useful for fluidly coupling the HP line 22 to the well(s) 76 and/or other or component(s). It should be noted, however, the above number and type of inlets 24, 64 and outlets 34, 66 are provided for illustrative purposes only. In practice, for example, the actual quantity and type of inlets 24, 64 and outlets 34, 66, when included, may vary depending upon the needs at a particular job and/or other variables. Thus, the present disclosure is not limited to the above type, quantity, configuration and function of inlets 24, 64 and outlets 34, 66, except and only to the extent as may be expressly specified otherwise herein or in a particular appended claim and only for such claim(s) and potentially one or more claims depending therefrom.

Components and connections without welds may last longer than if welded, have a greater useful lifespan and obviate the need to obtain welding permits or inspect job sites (e.g., to clear out gas and other ignitable sources), be more quickly and easily assembled, modified, disassembled, repaired and reconfigured, reduce down time, manpower needs, potential safety hazards, maintenance and repair efforts, have other benefits or a combination thereof. For example, the LP line 20 and/or HP line 22 may include at least one respective elongated spool 38 having a main bore 39 (e.g.,
Referring now to
In the present embodiment, the fasteners 16 are bolts and the receivers 29 are flanges 30 having one or more fastener holes 31 formed therein and provided on each spool 38 and/or other component (e.g., blender block 28, carrier 40, etc.). The illustrated receivers 29 (e.g., flanges 30) are integrally formed as part of the component (e.g., spool 38, blender block 28, carrier 40) without welding, such as through forging (or molding, casting, machining or other processes) or may be mechanically coupled thereto (e.g., bolted, pinned, threadably or otherwise mateably-connected). In other embodiments, though not preferred, welding may also or instead be used to couple one or more of the receivers 29 with its corresponding component (e.g., spool 38, blender block 28, carrier 40). The illustrated flange 30 extends radially-outwardly from the respective component (e.g., spool 38, blender block 28, carrier 40), but could instead extend radially inwardly, be flush with the respective component or configured in any other manner. Further, the receivers 29 may be provided at, or coupled to, any location on the spool 38 and/or other components, such as, for example, at, proximate to or spaced from one or both ends thereof or at one or more locations therebetween.
However, the fasteners 16 and receivers 29 may take any other suitable form. For example, receivers 29 may engage or mate with one another without the use of fasteners 16 or fastener holes 31, such as via threadable engagement, or be integrally formed together. Likewise, the mechanical connector 14 may take any other form and not include fasteners 16 and/or receivers 29. Accordingly, any suitable type and arrangement of mechanical connectors 14 may be used at any locations on the LP and/or HP lines 20, 22 to couple components together (e.g., without welding), such as, without limitation, clips, Chinese-finger-like portions, push-to-connect fittings (e.g., SharkBite™ fittings), hubbed connections, snaps, ratchet or gripping portions, clamps, hammer-union connections, threaded or otherwise mateable flanges, sleeves or other portions or a combination thereof. Thus, the present disclosure is not limited to the above form, configuration and operation of mechanical connectors 14, except and only to the extent as may be expressly specified otherwise herein or in a particular appended claim and only for such claim(s) and potentially one or more claims depending therefrom. Further, other forms of connecting components and/or welds (not preferred) may be used in addition to or instead of the mechanical connectors 14 to make up various components of the LP and/or HP lines 20, 22, or each LP line 20 and/or HP line 22 may be formed of a single integral respective component.

Referring briefly to
This may be accomplished in any suitable manner. For example, the LP inlet 24 may include at least one (e.g., hammer union) adapter 43 or other component releasably mechanically engageable with the blender manifold 26. In the present embodiment, the adapter 43 is releasably mechanically coupled to an adapter flange 58 that releasably mechanically engages a spacer spool 59, which releasably mechanically engages a receiver 29 (e.g., flange 30) integrally formed into (or mechanically connected to) the blender manifold 26.
In other embodiments, the LP inlet 24 may be releasably coupled to the blender manifold 26 (or other component) with any other form of connector (e.g., pins, clips, Chinese-finger-like portions, push-to-connect fittings (e.g., SharkBite™ fittings), snaps, ratchet or gripping portions, clamps, hubbed connections, threaded or otherwise mateable flanges, sleeves or other portions), and/or with the use of welds, or may instead be integral therewith or otherwise not removable therefrom. In the illustrated embodiment, a valve 42 (e.g., butterfly valve assembly) is shown associated with the LP inlet 24, but the LP inlet 24 may have any other parts. Thus, the present disclosure is not limited to this arrangement of exemplary components and parts associated with the LP inlet 24, except and only to the extent as may be expressly specified otherwise herein or in a particular appended claim and only for such claim(s) and potentially one or more claims depending therefrom.

The adapter spool 46, when included, may have any suitable form, configuration, components, construction and operation. The exemplary adapter spool 46 extends from the rear 52b of the blender block 28 and is releasably mechanically and fluidly engageable therewith, such as to easily switch out the adapter spool 46 to match the particular size (e.g., diameter) of the corresponding spool(s) 38 (or other component) of the LP line 20, for repair or replacement, to provide access into the blender block 28 for inspection, maintenance or the like and/or for any other purposes. In the present embodiment, mechanical connectors 14 may be used. For example, each end of the adapter spool 46 may include a receiver 29 (e.g., flange 30) or any other suitable feature or components for releasable mechanical engagement without welds to the blender block 28 at one end and an end spool 38a (or other component) of the LP line 20 at the opposite end. If desired, the illustrated receivers 29 of the adapter spool 46 may be integrally formed therein or thereon without welding, such as through forging (or molding, casting, machining, etc.) or may be mechanically coupled (e.g., with bolts) thereto or with welds. In other embodiments, the adapter spool 46 may be integral with or welded to the blender block 28 or spool 38, or not included. Moreover, the blender manifold 26 (e.g., blender block 28) may be engageable with, or coupled to, one or more LP lines 20 in any other manner.

When included, the support surface(s) 48 may be provided in any suitable manner. For example, the illustrated blender block 28 may have an at least substantially rectangular shape (e.g., as shown) for providing maximum real estate in the form of one or more flat support surfaces 48. In the present embodiment, the blender block 28 includes a first support surface 48a at its front 52a configured to host the principal LP inlets 24 for the LP line 20 and a second support surface 48b at a first side 52c thereof to host additional LP inlets 24. If desired, one or more other support surfaces 48c could instead or also be provided at a second side 52d, the rear 52b, top 52e or bottom 52f of the blender block 28, on other part of the blender manifold 26, or a combination thereof. Likewise, any of the support surfaces 48 could host the principal and/or additional LP inlets 24 and/or have any other purposes. Moreover, when included, the blender block 28 may have any other shape (square, pentagonal, hexagonal, etc.) and configuration, and the support surfaces 48 may have any other shape (e.g., curved, stepped, angled) and location.

In another independent aspect of the present disclosure, in various embodiments, the frac missile 56 or missile skid 10 may include one or more LP lines 20 and one or more blender manifolds 26. For example, multiple LP lines 20 may be coupled to a single blender block 28, such as at different respective sides/ends 52a-f of the blender block 28. For another example, one or more LP lines 20 may be indirectly coupled to a single blender block 28, such as through the use of one or more flow connectors or loops (not shown) fluidly connecting the LP lines 20 together. In such instance, if desired, one or more valves may be included to selectively control the flow of fluid as between the LP lines 20 or fluidly isolate them.
For yet another example, such as shown in
For another example, the blender manifolds 26 may themselves be fluidly coupled together, such as via one or more connectors or other components extending therebetween, integral formation or welding. In
For yet a further example, multiple blender manifolds 26 may be selectively fluidly coupled together. This may be accomplished in any suitable manner. Referring to

When included, the carrier 40 may have any suitable form, configuration, construction and operation. For example, the carrier 40 may include a connector spool or any other component(s) that can carry at least one LP outlet 34 and be fluidly coupled in, or to, an LP line 20. In the present embodiment, the carrier 40 includes a tee-assembly 41 having at least one LP outlet 34 and which is releasably engageable between, or with, adjacent spools 38 (and/or other components) in the LP line 20. The illustrated LP line 20 has a series of tee-assemblies 41 configured to be fluidly engaged between adjacent pairs of spools 38 (and/or other components). However, the carrier 40 could have any other form, configuration and components and be deployed in any other manner and location. For example, a carrier 40 may be engaged at one or both ends of the LP line(s) 20, two or more carriers 40 may be deployed side-by-side and engaged between a pair of spools 38, and so on.

In instances where different versions (e.g., types, sizes, ratings) of any of the exemplary LP components (e.g., spools 38, carriers 40, blender manifolds 26, LP inlets 24 and/or LP outlets 34) are needed or desired, such as to fit different sized frac or well equipment, accommodate the particular needs at a job site, make up different versions of LP lines 20 and/or for any other purposes, the members of each version of a particular component may be universal.
For still another example, a common or universal form of connection mechanism and/or technique(s) (e.g., tools) for interconnecting different types of components may be used. In the present embodiment, the same form of mechanical connectors 14 can be used for interconnecting all, or substantially all, of the various components and sub-components (e.g., spools 38, carriers 40, LP inlets 24, LP outlets 34, spacer spools 32, blender manifolds 26, blender blocks 28, caps 54, caps 36, valves 33, 35 and 42, caps 36 and 54, adapters 43, adapter spools 46, adapter flanges 58, spacer spools 59) of the LP line 20. Moreover, the mechanical connectors 14 (e.g., flange 30, hub, threads) associated with all, or substantially, all of the various components and sub-components of the LP line 20 may be integrally formed therewith (e.g., via forging, molding, casting, machining or other processes) or mechanically coupled thereto (e.g., via threadable connection) to avoid welding. (In some cases, some welding may be used.) Further, the exemplary LP line 20 itself may be universal and/or reversible (non-direction-specific) and used at any location and in any configuration on a missile skid 10 or in a frac missile 56 and accommodate fluid flow in either direction.
