Abstract

PURPOSE:To strongly join a joint to a pipe end even in case of a large diameter crosslinked polyethylene pipe by a method wherein; firstly, adhesive is applied under heating onto the outer surface of the pipe end and onto the inner surface of the joint; secondly, the pipe end is inserted in the joint; thirdly, a core jig is inserted in said pipe end and at the same time the junction is clamped by elastic tape from outside and finally the pipe end and the joint are cooled down. CONSTITUTION:In order to join a crosslinked polyethylene joint 2 to the end 10 of a crosslinked polyethylene pipe 1, first, the pipe end 10 and the joint 2 are fully heated with a heating jig 3. Secondly, after the pipe end and the joint are released from the heating jig, adhesive 4 is applied onto the outer surface of the pipe end 10 and onto the inner surface of the joint 2. Thirdly, after the application of the adhesive, the pipe end 10 is inserted in the joint 2. Fourthly, a core jig 5 is inserted in the pipe end 10. The re-heating of the pipe end and the joint is permissible just before the insertion of the pipe end 10 into the joint 2. Finally, an elastic tape 6 is wound onto the outer periphery of the joint 2 in order to clamp the junction from outside. The joint is strongly joined to the pipe end by the combined application of the jig with an elastic tape in addition to the application of the adhesive for join the crosslinked polyethylene joint to the crosslinked polyethylene pipe end.
