摘要： A mechanical pipe joint, restraining gasket, and method for restraining pipe spigots within adjacent bell sockets. The restraining gasket is composed of two axially-separate components: a sealing portion and a restraining portion made of a plurality of arcuate locking members. The restraining gasket and a gland surround an outer surface of the pipe spigot. The mechanical pipe joint is formed as the pipe spigot is inserted into the bell socket and the gland is axially attached to the bell socket so that the restraining gasket is held between: the gland, an inner surface of the bell socket, and the outer surface of the pipe spigot, so as to provide a fluid seal in the joint and urge the locking members into contact with the outer surface of the pipe spigot, axially restraining the pipe spigot within the bell socket.

摘要： A locking segment for use in connecting two lengths of pipe has a radically extending heel that serves as a rotational brake. By mating the brake into an annular trough, that is, by placing it between two walls, the rotation of the segment can continue only until points on the brake mure between the two walls. Rotation of the segment in response to increasing thrust pressures can thereby be arrested before the rotation causes the segment to bear on the spigot with a radically inward force great enough to penetrate the spigot.

摘要： A flanged-pipe fitting for joining the plain ends of pipe is described. The fitting comprises a tubular body having an interior cylindrical chamber with a first and second openings, an annular ridge located between the first and second openings, an annular recess for receiving a first sealing gasket and an annular flanged portion having a notch for receiving a second sealing gasket. The flanged-pipe fitting is used in conjunction with a gland fitting to join the two ends of the pipe together.

摘要： A gasket for connecting two lengths of pipe in a standard mechanical joint is disclosed, which gasket maximizes the advantages of both restrained push-on joints as well as mechanical joints, as are known commonly in the art. The invention has application to long-run pipe lengths as well as appurtenances, including fittings and connections. The gasket contains locking members that act to restrain separation upon the instance of any force tending to separate the connected pipe lengths.

摘要： A gasket for preventing separation of interconnected pipes including a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes an inner surface having at least one tooth configured for engaging a spigot end of a pipe and an outer surface having an arm with a substantially flat portion arranged adjacent to a forward section of a retainer groove of the gasket, the substantially flat portion being configured for displacing the segment radially and axially upon insertion of the spigot end into a bell end of the other pipe thereby decreasing the spigot insertion force required to seat the spigot end within the bell end and the gasket.

摘要： A locking ring designed to work in a self restraining pipe joint. This locking ring is designed (which may include attention to a combination of shape and material properties) to twist when exposed to a concentrated load and thereby distribute this load across broader area of the pipe joint to increase the thrust restraining capabilities of the joint
