OCTG Coating Pipe

Various steel pipe external coating projects are currently implemented by our company including single-layer/double-layer FBE, 2PE ,3PE,3PP and other anti-corrosion coatings with the performed standards such as DIN30670, DIN30671, DIN30678, CAN/CSA-Z245 21-M92, SY/T4013-2002 and SY/T0315-97 etc.

Coating pipe means the pipe that is by the processing after the corrosion, which can effectively prevent or slow the steel pipe occurs in the course of transport and chemical or electrochemical reaction corrosion phenomena. Coated steel pipe can effectively prevent or slow down the corrosion of steel pipes to extend service life and reduce operating costs pipe.

Applications of coating pipe:

coating 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 structures, piling and other marine water.

Standard:

DIN 30670: Polyethylene coatings of steel pipes and fittings.

DIN 30678: Polyethylene coating of steel pipes and fittings.

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

Anti-corrosion coating:

Various steel pipe external coating projects are currently implemented by our company including single-layer/double-layer FBE, 2PE ,3PE,3PP and other anti-corrosion coatings with the performed standards such as DIN30670, DIN30671, DIN30678, CAN/CSA-Z245 21-M92, SY/T4013-2002 and SY/T0315-97 etc.

Types of anti-corrosion coating.

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. Resistant to Chemical corrosion, cathodic stripping, resistance to mechanical damage performance.

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