The structure and performance of steel pipe products
Product presentation
"Sushan Shuijiang" brand steel frame polyethylene plastic composite pipe is a kind of steel wire mesh that is wound and welded as the reinforcing frame, and thermoplastic plastics such as polyethylene as the matrix, and the two are evenly compounded together. Composite structural pipes for continuous production. The polyethylene raw material for the production of steel skeleton polyethylene plastic composite pipe adopts the special material for high-density polyethylene pipe or the special material for medium-density polyethylene pipe (gas transportation), and the steel wire adopts ordinary low-carbon steel wire. It is mainly suitable for oil, gas, sewage transportation and mixed transportation in petroleum and natural gas industries, as well as drinking water, fire fighting and corrosive medium transportation. The operating temperature is -40°C ~ 80°C.
Pipe production process
Product features
Steel skeleton polyethylene plastic composite pipe has the common characteristics of anti-corrosion, no scaling, smooth low resistance, heat preservation, no condensation, wear resistance, light weight and other plastic pipe, and its unique structure also created the following characteristics:
• Good creep resistance, high lasting mechanical strength
