发明名称 Tubular bodies and methods of joining or repairing the same
摘要 A tubular body or pipe 100 comprises an inner hollow core 106 and an outer casing 104 having a helically extending rib portion 102. A tubular member 110, 112 has helical grooves 114 on its inner surface that may engage with rib 102. The tubular member 110,112 may be used for securing ends of two pipes 100 together or may be used to facilitate repair of a defective portion of pipe 100, or to secure a flange to the pipe 100. There is a structural member between the pipe and the tubular member, which may be an adhesive, or a solid or segmented ring 120. The ring 120 is inserted into any gap between the pipe and the core to fill the void that would otherwise exist.
