Title:
HEATING FUSION JOINT, CONNECTION METHOD THEREOF AND CONNECTOR
Document Type and Number:
Japanese Patent JP2017227228
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heating fusion joint enabling fusion connection even in a case of being used as resin material with high melting point and resin hard to melt, and a heating fusion connection method between the heating fusion joint and a pipe.SOLUTION: In an inner peripheral surface of insertion holes 2, 3 of a heating fusion joint 1, a range of distance Lfrom an inlet side is composed of an inner peripheral surface layer 5 comprising thermoplastic resin material with a low fusion temperature. The inner peripheral surface layer 5 is non-crosslinked polyethylene, and a heating fusion joint body part 6 is crosslinked polyethylene. A pipe 10 inserted into the insertion holes 2, 3 includes a first layer 11 comprising the crosslinked polyethylene, and a second layer comprising the non-crosslinked polyethylene.SELECTED DRAWING: Figure 4
