Title:
HIGH-PRESSURE CONNECTING STRUCTURE FOR STEEL WIRE MESH REINFORCED COMPOSITE PIPES AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/071000
Kind Code:
A1
Abstract:
A high-pressure connecting structure for steel wire mesh reinforced composite pipes and a manufacturing method therefor. The high-pressure connecting structure comprises a first connecting assembly arranged on an end portion of a first composite pipe (1), a second connecting assembly arranged on an end portion of a second composite pipe (10), and a bolt assembly configured to fixedly connect the first connecting assembly and the second connecting assembly, wherein steel wire layer exposed sections are respectively arranged at joints of the end portions of the first composite pipe (1) and the second composite pipe (10), and the first connecting assembly comprises a concave flange (3) arranged on the steel wire layer exposed section of the first composite pipe (1) and a Hough section (2) arranged on an outer layer of the first composite pipe (1); and the second connecting assembly comprises a convex flange (9) arranged on the steel wire layer exposed section of the second composite pipe (10) and a Hough section (2) arranged on an outer layer of the second composite pipe (10). According to the high-pressure connecting structure, the flanges are arranged on steel wire layers, and the flanges are locked by means of the Hough sections, so that compared with existing connecting manners, the connection pressure bearing capacity is greatly improved, and the connecting structure has a simple manufacturing process and is convenient to construct.
