    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: A manhole assembly for a manhole having generally cylindrical sidewalls defined between an outside surface and an inside surface separated by a wall thickness and having a wall opening communicating the outside and inside sidewall surfaces of the manhole for insertion of a mating pipe. The wall opening defines a peripheral surface relatively perpendicular to the outside and inside sidewall surfaces which receives a ring shaped elastomeric gasket. The gasket has a retaining ring whose location is precisely determined to allow the gasket to be obliquely inserted within the wall opening of the manhole and to be subsequently snap-fitted into position on the peripheral surface, whereby the gasket is securely retained in a locked-in position with respect to the wall opening in the sidewall of the manhole.

    摘要: An improved pipe belling process is shown which a gasket is installed on the outer working surface of a forming mandrel at one circumferential location. The heated socket end of a thermoplastic pipe is forced over the mandrel exterior and over the gasket causing the heated socket end of the pipe to flow over the gasket and form a retention groove for retaining the gasket before again contacting the working surface of the mandrel. The heated end of the pipe is cooled and retracted from the working surface of the mandrel. The gasket has a non-stick, anti-friction coating applied to portions of the exterior thereof.

    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 the belled, socket end of a plastic pipe. The sealing gasket has a body formed of resilient material and has a retainer ring embedded therein which circumscribes the gasket body. The groove in the plastic pipe is preformed during the manufacture of the plastic pipe and the gasket is installed thereafter. The gasket nominal diameter exceeds the internal diameter of the belled pipe end. The retainer ring is placed within the body of the sealing gasket at a precisely determined location which most effectively retains the ring in position while withstanding the forces of the assembly of the pipe joint.

The groove in the plastic pipe is preformed during manufacture and the gasket is installed thereafter. The gasket nominal diameter exceeds the internal diameter of the belled pipe end. A special installation tool is used to pull the gasket from an initially deformed, elliptical shape to a normal cylindrical shape. The installation tool uses only one fluid cylinder for power and can be hand installed and operated.
