Tank connector construction and method of fabrication.

摘要

A tank connector construction for a tank. The tank is comprised of an outer shell (370) of metal material and an inner shell (396) of non-corrosive and non-metallic material mounted inside the outer shell (370). A metal connector fitting (372) is provided which has an internal threaded body portion (376), an internal groove (378) and a weld projection portion (374) on the inner end thereof. The weld projection portion (374) of the fitting (372) is welded to the outer shell (370) of the tank. A sleeve member of non-corrosive and non-metallic material is mounted in the internal groove (378) of the connector fitting (372). An extension portion of non-corrosive and non-metallic material is formed integrally with the inner shell (396) of the tank and is fused to the material of the sleeve (380) to prevent contact between the contents of the tank and the outer shell of the tank. The extension portion of non-corrosive and non-metallic material has a threaded portion which forms a continuation of the internal threaded body portion of the metal connector fitting. <IMAGE>
