Background
The connecting method of the composite material pipeline generally comprises two main types of mechanical pressing mode and non-mechanical pressing mode. The most widely used of these is mechanical compaction. The principle of the mechanical compression mode is that all layers of the composite pipe are compressed to the joint piece under the mechanical action, so that the axial load transmission is realized while the sealing is realized. However, the high-pressure flexible composite pipe has the reinforcing layer, and the structure of the reinforcing layer is easily damaged by adopting a mechanical compression mode, and particularly for the flexible composite pipe which has higher pressure bearing capacity and is made of a composite material with a reinforcing layer having higher brittleness, once the reinforcing layer is damaged, the load transmission is weakened, the pressure bearing capacity is reduced, and leakage accidents are easily caused.

The tail end of the pipe joint is a free connecting section and can be connected with other structural components in the forms of threads, welding and the like according to actual requirements. However, the existing pipe joint for the flexible composite pipe adopts threaded connection, the phenomena of thread abrasion and thread slipping are only 'connection' in meaning rather than 'connection' of an integral type after a long time, the service life is short, two pipe fittings cannot be fused together to form the integral type, and the problem that the load borne by the pipe fittings in the working process is small is solved.
