Document Type and Number:
WIPO Patent Application WO/2018/142500
Kind Code:
A1
Abstract:
The present invention enables manufacturing of a plumbing reinforcement material with which it is possible to effectively reduce stress exerted in the axial direction of a pipe. This method comprises: a preparation step (step S3a) for preparing a tubular member (125) having a profile larger than that of a portion to be reinforced of a pipe (150); and a segmentation step (step S5) for segmenting the tubular member along a segmentation line (127) parallel to the axial direction so as to form a plurality of segmented pieces (129). The reinforcement material (100) obtained by the present invention comprises a plurality of segmented bodies (110) having an integral structure in the axial direction.
