  • Precision seamless steel pipe

    Precision seamless steel pipe

    Precision seamless steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling treatment. Because there is no oxide layer on the inner and outer wall of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no crack, it is mainly used to produce products of pneumatic or hydraulic components, such as air cylinder or oil cylinder.

  • Hydraulic cylinder seamless steel pipe

    Hydraulic cylinder seamless steel pipe

    Hydraulic cylinder seamless steel pipe is suitable for oil, hydraulic cylinder, mechanical processing, thick wall pipeline, chemical industry, electric power, boiler industry, high temperature, low temperature and corrosion resistance seamless steel pipe, and it is suitable for petroleum, aviation, smelting, food, water conservancy, electric power, chemical industry, chemical fiber, medical machinery and other industries.

  • Plastic coated steel pipe

    Plastic coated steel pipe

    The inner and outer plastic-coated steel pipes are made by melting a layer of polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, and non-toxic polycarbonate with a thickness of 0.5 to 1.0mm on the inner wall of the steel pipe. The steel-plastic composite pipe composed of organic substances such as propylene (PP) or non-toxic polyvinyl chloride (PVC) not only has the advantages of high strength, easy connection, and resistance to water flow, but also overcomes the corrosion of steel pipes when exposed to water. Pollution, scaling, low strength of plastic pipes, poor fire-fighting performance and other shortcomings, the design life can be up to 50 years. The main disadvantage is that it must not be bent during installation. During thermal processing and electric welding cutting, the cutting surface should be painted with the non-toxic normal temperature curing glue provided by the manufacturer to repair the damaged part.
