プラスチツク管破壊試験用管端継手。[Claims for Utility Model Registration] A tapered split ring with multiple pointed protrusions on the inner circumferential surface and a crack formed on the slope, a tapered heat-resistant rubber packing, an internally threaded packing holder with a cross section of [shaped], and a cylindrical shape. A pipe end fitting consisting of a male threaded cover and a tapered split ring that is fitted onto the outside of the tube under test. The tip of the male threaded cover that screws into the female threaded packing fits onto the outer periphery of the tapered heat-resistant rubber packing fitted externally to the pipe, and by tightening the female threaded packing holder, the inner protrusion of the tapered split ring is tested. A pipe end joint for destructive testing of plastic pipes, characterized by having a structure in which a tapered heat-resistant rubber packing is pressed against the tube under test while biting into the pipe.
