Title:
配管の接続構造、配管の接続方法およびシート状のテープ
Document Type and Number:
Japanese Patent JP6674676
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a connection structure of pipeline, a connection method of pipeline, and a sheet-like tape capable of preventing an inner pipe part from being exposed since a tape does not deviate from the inner pipe part even if the pipeline expands/contracts in a pipe axial direction while the proof pressure reinforcement of end edges of the pipeline and connection points with other pipeline can be executed by a simple and low-cost work.SOLUTION: A connection structure of pipeline 1a comprises: pipeline 10; a plurality of fibers 34 extending in a longer direction; and a sheet-like tape 30 in which each fiber 34 is held by a thermoplastic resin, in which at least an exposed portion of an inner pipe part 12 in the pipeline 10 is thermally fused to the sheet-like tape 30; and the vicinity of the connection points with other pipeline in end parts of the pipeline 10 is covered with the sheet-like tape 30, so that each fiber 34 of the tape 30 is substantially orthogonal to the pipe axial direction of the pipeline 10.SELECTED DRAWING: Figure 4
