    摘要: A combination sealing and restraint system for an as-cast ductile iron fitting is shown for both sealing and preventing separation of an iron pipe fitting and a mating male pipe. A ring-shaped body is installed within a mating groove provided in a mouth region of the as-cast fitting after the fitting has been cast at the manufacturing plant. The ring-shaped body is formed of an injection molded elastomeric material and carries a series of gripping segments which have teeth on an inner surface thereof which are designed to engage an outer surface of a mating male pipe. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening o f the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The gripping segments are mechanically bonded to the elastomeric body of the gasket during the injection molding operation. The ring-shaped body also includes a relatively flexible portion formed of an elastomer which forms a lip seal region with the mating male pipe.

A ring-shaped body is installed within a mating groove provided in a mouth region of the as-cast fitting after the fitting has been cast at the manufacturing plant. The ring-shaped body carries a gripping member with teeth on an inner surface thereof which are initially angled away from an outer surface of a mating male pipe. The teeth are forced into engagement with the exterior surface of the mating male pipe as the pipe joint at the fitting is assembled. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening of the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The ring-shaped body also includes a relatively flexible portion formed of an elastomer which forms a sealing member with the mating male pipe.

    摘要: A combination sealing and restraint system for an as-cast ductile iron fitting is shown for both sealing and preventing separation of an iron pipe fitting and a mating male pipe. The restraint system includes both a sealing ring and a combination gripping ring which are installed in a groove provided in a mouth region of the iron fitting. The gripping ring has teeth on an inner surface which are initially angled away from an outer surface of the male pipe. The teeth are forced into engagement with the exterior surface of the mating male pipe as the pipe joint at the fitting is assembled. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening of the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The sealing ring and gripping ring are installed in the annular groove of the as-cast iron fitting after the iron casting operation at the factory.

    摘要: An apparatus for restraining pipe against both internal and external forces at a pipe or fitting connection and to join and seal at least two pipes to form a pipeline featuring an improved restraining and sealing mechanism. The restraining and sealing mechanism includes a circumferential housing and a companion sealing ring which are received within a mating groove provided in the belled end of a female pipe. The circumferential housing has an interior region which contains a gripping ring insert. The sealing ring and housing are integrally located within a belled pipe end during belling operations.

    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.

    摘要: A restraining gasket for both sealing and preventing separation of a pipe joint used to join a bell end of a female ductile iron pipe to the male end of a mating ductile iron pipe. The gasket has a body formed from a compressible elastomeric material having a hardened metal ring located therein with gripping teeth. The hardened ring has an opening at one point in its circumference which is filled with rubber. The rubber-filled gap ensures that the gasket body seals first prior to engagement of the gripping teeth as the pipe joint is assembled.
