Description

3PE coating pipe is short for “three layers structure polyethylene anticorrosion coating steel pipe”. There are three layers in this pipe coating structure:

  • · The first one: Epoxy layer (Thickness > 100um)
  • · The second one: Adhesive layer (Thickness: 170um~250um)
  • · The third one: Polyethylene layer (Thickness: 1.8~3.7mm)



What kind of pipes could be coated with 3PE or FBE 

Coating standard:

  • ANSI/AWWA C104/A21.4 American National Standard for Cement-Mortar Lining for Ductile-Iron Pipe and Fittings for Water
  • ISO 21809 Petroleum and natural gas industries -- External coatings for buried or submerged pipelines used in pipeline transportation systems
  • DIN 30670 Polyethylen coatings of steel pipes and fittings 
Size:
  • Outer Diamter: 219.1mm - 4064mm (8" - 160")
  • Wall Thickness: 3.2 mm - 40mm
  • Length: 6mtr-18mtr
End
