Japanese Patent JP2015175482
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pipe body connection structure between a multi-layer pipe covered at an outer circumferential surface by a reinforcing layer and another pipe body showing a superior anti-pressure effect.SOLUTION: A pipe body connection structure 100 comprises a first pipe body 200, a second pipe body 300, a welding part 400 and a fiber-reinforced resin layer 500. The first pipe body 200 includes a pipe main body part having a reinforcing layer 220 and a connecting end part T having no reinforcing layer 220. The second pipe body 300 has, at its inner circumferential surface, a part T1 of a connecting end part T of a connecting end part of the first pipe body 200 internally inserted and connected. The welding part 400 welds another part T2 of the connecting end part T with a connecting end surface 315 of the second pipe body 300. The fiber-reinforced resin layer 500 includes filaments covering at least a surface of the welding part 400 and wound in a circumferential direction of the first pipe body 200 to cause their thread length directions to extend along the circumferential direction of the first pipe body 200 and a cloth covering the wound filaments.
