hdpe lined steel pipe

HDPE lined steel pipe

  • Origin:Tianjin, China
  • Price:FOB,CIF,CFR
  • Min order: 5 tons
  • Technical:erw
  • Material: HDPE/PE


Based on, plain carbon steel pipe lined with chemical excellent thermoplastic plastic, the cold tensile or roll forming, it has both the mechanical properties of steel pipe and plastic pipe corrosion resistance, low scale, not easy to the characteristics of the microbial growth, is the transmission of acid, alkali, salt, corrosive gases such as ideal medium pipeline. It is widely used in chemical, biological, electric power, metallurgy, pharmacy, food, environmental protection and other fields, It is to replace rubber porcelain, glass reinforced plastics, stainless steel and plastic lining ideal material in – 20 ℃ — 105 ℃.

We  produce a full range of  HDPE lined steel pipe in:

  • ERW black or hot-dipped galvanised
  • Specification:DN15-DN500
  • Thickness of PE(polyethylene) coating: 400um – 1000um
  • Temperature:-20℃—–80℃
  • Connection: screw fastener (dn15-dn100), groove (dn65-dn400), flange (applicable for any caliber), welding type, bimetallic connection, socket, pipe joint, sealing connection, etc
  • When the pipe is threaded, the working pressure of the system ≤1.0MPa.Threaded connections are used;when the working pressure of the system is between 1.0MPa and 1.6MPa,It is advisable to apply (liner) plastic seamless steel pipe, seamless steel pipe or ductile iron plastic pipe fitting, flange connection or groove connection;
    when the working pressure of the system is between 1.6mpa and less than 2.5mpa,It is advisable to apply seamless steel pipe and seamless steel pipe or plastic lined cast steel pipe fitting. Use flanged or grooved connections.
