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 sealing gasket is shown for use in a ductile iron piping system to form a sealed joint between mating male and female pipe ends. A sealing gasket body is provided with a series of retainer inserts which extend outwardly from a leading nose region of the elastomeric gasket body. The mating male pipe end contacts the retainer inserts prior to contacting the remainder of the gasket body during the make up of the pipe joint. The inserts help to retain the gasket within its associated groove during high pressure field conditions. The inserts are spaced circumferentially about the gasket nose region, allowing the gasket the necessary flexibility to allow insertion within the groove provided in the female, belled pipe end.

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 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 method and 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 is shown 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.
