Claims
- 1. A method for constructing a first fluid barrier, a fluid containment passage, and a second fluid barrier surrounding the junction of a first fluid passage terminating in a first surface and a second fluid passage terminating in a second surface, said method comprising the steps of:
- (a) forming a first groove in a first surface surrounding the termination of a first passage in said first surface, the inside perimeter of said first groove extending beyond the outside perimeter of said termination of the first passage in said first surface and the outside perimeter of said first surface extending beyond the outside perimeter of said first groove;
- (b) forming a second groove in a second surface surrounding the termination of a second passage in said second surface, the inside perimeter of said second groove extending beyond the outside perimeter of said termination of the passage in said second surface and the outside perimeter of said first surface extending beyond the outside perimeter of said second groove;
- (c) inserting a sheet of fluid barrier material between said first and second surfaces, said fluid barrier material having openings to permit fluid communication between passages terminating on the surfaces of said first surface and corresponding passages terminating on the surface of said second surface, the outside perimeter of said openings lying within the inside perimeter of said first and second grooves;
- (d) providing fluid communication between the said first groove and an external fluid disposal system;
- (e) providing fluid communication between the said second groove and an external fluid disposal system; and
- (f) compressing said sheet of fluid barrier material by forcing the first and second surfaces against opposing sides of said sheet of fluid barrier material.
- 2. The method of claim 1 where the thickness of the sheet of fluid barrier material is less than 0.040 inches.
- 3. The method of claim 2 where:
- (a) the force compressing the fluid barrier material is applied by one or more threaded members; and
- (b) the length of the threaded members and the force compressing the fluid barrier material result in a strain of a value equal to or exceeding the thickness of said fluid barrier material.
- 4. The method of claim 1 where the thickness of the sheet of fluid barrier material is less than 0.030 inches.
- 5. The method of claim 1 where the thickness of the sheet of fluid barrier material is less than 0.020 inches.
- 6. The method of claim 1 where the thickness of the sheet of fluid barrier material is less than 0.015 inches.
- 7. The method of claim 1 where the thickness of the sheet of fluid barrier material is less than 0.010 inches.
- 8. the method of claim 7 where;
- (a) the force compressing the sheet of fluid barrier material is applied by one or more threaded members and;
- (b) the length of the threaded and unthreaded members and the force compressing the sheet of fluid barrier material, result in a strain of a value equal to or exceeding the thickness of said sheet of fluid barrier material.
- 9. The method of claim 1 where the first and second surfaces are pressed against opposing surfaces of the sheet of fluid barrier material with a net force greater than 500 pounds per square inch of contact exclusive of the force exerted by internal fluid pressure.
- 10. The method of claim 9 wherein the net force is greater than 1000 pounds per square inch.
- 11. The method of claim 9 where the net force is greater than 1500 pounds per square inch.
- 12. The method of claim 9 where the net force is greater than 2000 pounds per square inch.
- 13. The method of claim 9 where the net force is greater than 2500 pounds per square inch.
- 14. The method of claim 9 where force applied to the first and second surfaces results in displacement of sheet fluid barrier material to a point where said first surface and second surface make contact.
- 15. The method of claim 9 where:
- (a) the force compressing the sheet of fluid barrier material is applied by one or more threaded members and;
- (b) the length of the threaded and unthreaded members and the force compressing the sheet of fluid barrier material, result in a strain of a value equal to or exceeding the thickness of said sheet of fluid barrier material.
- 16. The method of claim 1 where;
- (a) the force compressing the sheet of fluid barrier material is applied by one or more threaded members and;
- (b) the length of the threaded and unthreaded members and the force compressing the sheet of fluid barrier material, result in a strain of a value equal to or exceeding the thickness of said sheet of fluid barrier material.
- 17. The method of claim 16 where the thickness of the fluid barrier material is less than 0.040 inches.
- 18. The method of claim 16 where the thickness of the fluid barrier material is less than 0.030 inches.
- 19. The method of claim 16 where the thickness of the fluid barrier material is less than 0.020 inches.
- 20. The method of claim 16 where the thickness of the fluid barrier material is less than 0.015 inches.
- 21. The method of claim 16 where the thickness of the fluid barrier material is less than 0.010 inches.
- 22. The method of claim 16 where said first surface is sloped in opposition to the direction of applied fluid pressure.
- 23. The method of claim 16 where the said second surface is sloped in opposition to the direction of applied fluid pressure.
