Strength design of tubular textile composites for pipeline rehabilitation under internal pressure

The tubular textile composite material is lined on the inner wall of the pipeline by the inversion method, and realizes the structural or semi-structural repair of the pipeline in the form of “pipe in pipe”. Under the action of inversion pressure and working internal pressure, its strength directly affects the repair effect. In this paper, the pressure in the process of inversion and conveying medium is discussed, using theories such as the...
