Pressure Testing of Steel Wire Mesh Framework Composite Pipe

Steel wire mesh skeleton composite pipe is a new type of PE composite pipe. Its inner and outer surfaces are composed of polyethylene, and the middle is wrapped with steel wire to form a network. Modified resin is used to combine the two.
After the pressure testing equipment system stabilizes, increase the pressure to 1.5 times the working pressure, maintain the pressure for one and a half hours, carefully observe the pressure gauge, and patrol along the line. If there is no visible leakage or significant pressure drop during the testing process. When welding replacement electric fusion pipe fittings, it is necessary to ensure that there is no accumulated water inside the pipeline, otherwise it is difficult to weld the electric fusion pipe fittings firmly. After welding is completed, it must be allowed to cool for more than 120 minutes before water can be used for pressure testing.
