    Pipe screw barrel is a kind of equipment specially used for processing pipe materials, mainly used in the production of plastic pipes.
    The following are some applications of tubing screw barrels: PVC pipes: Pipe screw barrels can be used to process pipes made of polyvinyl chloride (PVC), such as water supply pipes, drainage pipes, wire and cable sheathing pipes, etc.

    PE pipe: pipe screw barrel can also be used to process pipes made of polyethylene (PE), such as water supply pipes, gas pipes, communication cable sheath pipes, etc. PP pipe: Polypropylene (PP) material can also be processed into pipes through pipe screw barrel, such as chemical pipes, ventilation pipes, etc.

    PPR pipe: The pipe screw barrel can also be used to produce polypropylene thermal composite pipe (PPR pipe), which is often used in building water supply and heating systems.

    ABS pipe: the pipe screw barrel can also process pipes made of acrylonitrile-butadiene-styrene copolymer (ABS), which are often used in industrial pipes, chemical pipes, etc.

    PC pipes: Polycarbonate (PC) materials can also be processed into pipes through pipe screw barrels, such as irrigation pipes, FRP reinforced pipes, etc.

    In summary, pipe screw barrels are mainly used in the production of plastic pipes, which can process pipes of various materials to meet the needs of different fields, including construction, chemical industry, water supply and drainage, gas and other industries.
