摘要： An expansion tool includes a housing and a collar rotatably coupled to the housing. The collar includes a plurality of slots. The expansion tool further includes a plurality of jaws, each jaw having a projection received in a corresponding one of the plurality of slots such that the jaws are coupled for co-rotation with the collar. The expansion tool also includes a mandrel movable relative to the housing between a retracted position and an extended position, the mandrel engageable with the jaws to expand the jaws in response to movement of the mandrel to the extended position, and a drive mechanism including a rotatable cam. Rotation of the cam moves the mandrel between the retracted position and the extended position. The expansion tool further includes a rotation mechanism configured to incrementally rotate the collar.

摘要： A polymer pipe has a length between a first end and a second end. The length and the first end have a first diameter and the second end is a belled end having a second diameter larger than the first diameter. An insert device is received or pre-installed within the second end and has an annular body with a seal part coupled to the annular body and a spline groove formed in the annular body and facing radially inward. Another polymer pipe is inserted in the belled end to form a pipe joint assembly and has a mating spline groove on the outer surface. The spline groove and mating spline groove axially align and receive a spline therein to axially interlock the two polymer pipes to form a pipe joint assembly.
