摘要： An sealing gasket is shown for use in forming joints of plastic pipe. The gasket has a bulbous region which is bisected by a planar region which forms a pair of oppositely extending wing-like flaps. These features of the gasket allow it to be more reliably seated on the working mandrel used to bell a female, thermoplastic pipe end. The wing-like flap portions of the gasket form wiper surfaces for a subsequently installed male, spigot pipe end as the joint is formed.

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.

摘要： A pipe sealing gasket is shown which is designed to be received within a groove provided within a socket end of a thermoplastic pipe in a pipe sealing system. The sealing system includes a male, spigot pipe end which is joined to a mating female belled pipe end. The belled pipe end has an internal groove adjacent a mouth region thereof which is simultaneously formed under temperature and pressure as the mouth region is forced over a forming mandrel and about a sealing gasket located on the forming mandrel so that the sealing gasket is prelocated within the internal groove. The sealing gaskets of the invention have a specially designed sealing capability to seal volume ratio.

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 pipe sealing gasket is shown which is designed to be received within a groove provided within a socket end of a thermoplastic pipe in a pipe sealing system. The sealing system includes a male, spigot pipe end which is joined to a mating female belled pipe end. The belled pipe end has an internal groove adjacent a mouth region thereof which is simultaneously formed under temperature and pressure as the mouth region is forced over a forming mandrel and about a sealing gasket located on the forming mandrel so that the sealing gasket is prelocated within the internal groove. The sealing gaskets of the invention have a sealing capability to seal volume ratio which is numerically related to the same sealing capability to seal volume ratio of prior art gasket designs by a multiplying factor of 2:1 or more.

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.
