Composite tube
By using a hollow cylindrical liner and flange end attachments in the composite pipe, combined with a thermosetting outer layer of impregnated resin filaments, the failure problem caused by microcracks during handling and transportation of the composite pipe is solved, achieving stability and strength for fluid transportation under high pressure or high temperature.

AI Technical Summary
Existing high-strength composite pipes are prone to structural failure due to microcracks during handling and transportation, especially when transporting fluids under high pressure or high temperature, where microcracks may propagate and lead to leakage and rupture.
The design employs a hollow cylindrical liner and flange end attachments. The outer layer consists of a thermosetting material made of resin-impregnated filaments wrapped around the outer surface of the liner and flange end attachments, which enhances the structural strength. The composite tube is constructed through a simple extrusion process, reducing the need for threads or complex connections.
It improves the structural integrity of the composite pipe, reduces the risk of failure caused by microcracks, and enhances its mechanical strength during handling and transportation, making it suitable for high-pressure or high-temperature fluid transportation.
