Maximum working pressure evaluation system and method for multi-layer non-metal material composite pipe

The invention discloses a system and a method for evaluating the maximum working pressure of a multi-layer non-metal material composite pipe, the evaluation system performs pressure test on a test unit group through a pressure loading system and a water source system, and a medium isolation type pressure transmission device is regulated and controlled in the test unit group through a series of control valve assemblies. The medium isolation type pressure transmission device is connected with a non-metal material composite pipe sample assembled in a temperature control box, field service temperature simulation is achieved by adjusting the temperature of the temperature control box, and the pressure of the medium isolation type pressure transmission device is adjusted and controlled according to a series of control valve assemblies. The pressure of a sample is effectively tested, field service internal pressure simulation is achieved, field service conveying medium simulation can be achieved through a test mediu
