Integral restraint system and method of manufacture for plastic pipe |
摘要 |
A method and apparatus for restraining pipe against internal forces at a pipe or fitting connection and to join and seal at least two pipes to form a pipeline is shown featuring an improved restraining/sealing mechanism. The restraining/sealing mechanism includes a relatively rigid gripper ring and a companion sealing ring which are received within one or more mating grooves provided in the belled end of a female pipe. The gripper ring and sealing ring can be combined or attached, or they can be separate members located in the same retaining groove or separate grooves in the female belled pipe end.
