The anti-corrosion of plastic-coated steel pipes was developed from the earliest inner and outer polyethylene. Due to adhesion problems, it developed into inner and outer epoxy, but the outer epoxy layer was not resistant to bumping. Later, it developed into the third generation of inner epoxy and o

1. Compression type: Insert the pipe into the nozzle of the pipe fitting, fasten it with a nut, and compress the casing of the nozzle through the sealing ring with a screw force, which plays a sealing role and completes the connection of the pipe.2. Welding type: The end of the pipe is beveled, and
