Project Description

The coated pipes are composed of three functional components: a high-performance fusion bonded epoxy (FBE), followed by a copolymer adhesive and an outer layer of polyethylene which provides tough and durable protection.

Application:

Widely used as preservative pipeline. Such as:

  • Water supply pipeline
  • Gas transportation pipe line
  • Oil transportation pipe line
  • Mine, power, chemical transportation pipe line

Specification:

  • O.D.: 159mm ~ 1220mm
  • Coating Standard: DIN30670
  • Packing: Waterproof Paper wrapped, Steel Strips bundled
