Description

Technical Field

[0002] The structure of the metal composite pipe is composed of two or more different materials, and the pipe layers are tightly combined through various deformation and connection technologies. The metal composite pipe utilizes the best properties of the base material and the cladding metal. Compared with the integral alloy pipe, it can effectively reduce the cost and improve the safety and reliability of the application.

[0023] In this embodiment, a long composite pipe fixing fixture is made to meet the composite processing characteristics of titanium-steel composite pipes.
