LEFIN STEEL exported big quantity coated pipes for oil and gas ,water transportation pipes 

because steel pipe finished production ,easy to start rusting, for anti rust aim,we normally treated pipes with some kinds of coating

like painting,3LPE,3PE,FBE Coating etc.

coated steel pipe base metal is including spiral, straight seam pipe, seamless steel pipe, etc, which are widely used in pipeline projects in the field of petroleum, chemical, natural gas, heating, sewage treatment, water, bridges, steel structure, pilling and other marine water.


DIN 30670: Polyethylene coating of steel pipes and fittings.

DIN 30678: Poly3thylene coating of steel pipes and fittings

SY/T0413-2002: Technical standard of polyethylene coating for buried steel pipeline.


Pipe corrosion types are divided into external corrosion and internal corrosion.

Types of anti-corrosion coating

Mainly type for anti-corrossion:

1. FBE anticorrosive epoxy powder

FBE epoxy powder preservative structure: electrostatic spraying epoxy powder coating on the pipe surface, a film. The coating has a coating operation is simple, clean, good impact resistance and flexural properties of the coating, temperature resistance advantages.

2. 2PE/3PE corrosion

2PE/3PE corrosion structure: the steel surface electrostatic spraying epoxy powder and binder twine lateral wound polyethylene coating, combined with three excellent performances, thereby significantly improving the overall quality of corrosion of the pipe.

3. Coal tar epoxy

Coal tar epoxy structure: epoxy resin+ filler made of coal tar pitch anticorrosive coating on steel surface coated glass fabric as reinforcement corrosion layer formation, commonly used in the pipe wall corrosion thickness of 0.5-1.0mm
