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.
Widely used as preservative pipeline. Such as:
Application:
- 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
