Description

technical field

[0001] The invention belongs to the technical field of composite pipes and relates to a preparation process of flexible reinforced composite pipes. Background technique

[0002] The flexible composite pipe is a kind of high-strength, high-pressure, corrosion-resistant, anti-fouling, small friction coefficient, light weight, good heat preservation, good flexibility, good heat insulation performance, and high conveying pressure made of polymer composite materials. It is an industrial pipe fitting with the characteristics of high performance and long service life; it can effectively solve the problem of easy corrosion of metal pipes, and at the same time overcome the defects of non-metallic pipes such as corrosion resistance, pressure resistance, and poor mechanical properties.

[0003] After searching, for example, Chinese patent literature discloses a mica powder and graphene composite flexible tube [application number: 201711001139.8; publication number: CN 1...
