Claims
- 1. A tank connector assembly comprising:
- a metal spud member (24) having an upper internally threaded cylindrical portion (26) and a lower cylindrical wall portion (28) having an internal smooth wall surface portion;
- an insert member (14) of polymer material having a cylindrical wall portion, said wall portion having an internal and an external face, said insert member mounted inside said cylindrical wall portion of said spud member and spaced therefrom, said insert member (14) having an upper cylindrical section (20) and a lower cylindrical section (22) of a smaller diameter than said upper section to thereby form a shoulder (21) between said upper and lower cylindrical sections; and
- a bonding member (12) of polymer material having a cylindrical wall portion (18) having internal and external cylindrical wall surfaces, said cylindrical wall portion of said bonding member positioned in the space between the external surface of said cylindrical wall portion of said insert member and the internal surface of said cylindrical wall portion of said spud member, said internal and external wall surfaces of said cylindrical wall portion of said bonding member bonded to said external wall surface of said insert member and to said internal smooth wall surface of said spud member.
- 2. A tank and tank connector therefor comprising:
- an outer steel tank having at least one opening therein;
- an inner steel tank of polymer material mounted inside said outer steel tank;
- a tank connector assembly to facilitate a connection between the interior of said inner tank and the exterior of said outer tank, said tank connection assembly comprising:
- a metal spud member (24) having an upper internally threaded portion (26) and a lower cylindrical wall portion (28), said cylindrical wall portion welded to the steel outer tank at the opening therein;
- an insert member (14) of polymer material having a cylindrical wall portion, said insert member mounted inside said cylindrical wall portion of said spud member, said polymer material of said inner shell being bonded to said insert member, said insert member (14) having an upper cylindrical section (20) and a lower cylindrical section (22) of a smaller diameter than said upper section to thereby form a shoulder (21) between said upper and lower cylindrical sections, said shoulder being in snug engagement with said outer steel tank;
- a bonding member (12) of polymer material having a cylindrical wall portion (18 having internal and external cylindrical wall surfaces, said cylindrical wall portion of said bonding member positioned between the external surface of said cylindrical wall portion of said insert member and the internal surface of said cylindrical wall portion of said spud member, said internal and external wall surfaces of said cylindrical wall portion of said bonding member bonded to said insert member and to said lower cylindrical wall portion (28) of said spud member, respectively.
