  • Patent number: 4871197
    Abstract: 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.

  • Patent number: 4540204
    Abstract: 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.
