In the environment of telescoping pipes, a collapsible member is placed between a fixed weld and a locking segment so that when extraordinary forces are applied which tend to cause the pipes to be pulled apart, the crushing element absorbs the excessive forces and prevents its disengagement.

This invention pertains to a method of making a pipe gasket having an asymmetric profile which is made by connecting two ends of an extruded elastomeric material, and the gasket made thereby.

Method of making pipe-joint gasket

A bell and plain end pipe joint are provided wherein the plain end has a raised portion on its outside diameter. A series of locking segments fit into a circumferential groove in the bell of one pipe and engage both the raised portion on the plain pipe and a portion of the bell. Upon an increase in fluid pressure in the pipes, the pipes tend to separate axially and the locking segments also contact and bear against a different portion of the bell. The joint provides a novel means of distributing the axial thrust tending to separate the pipe being joined.
