Coated steel 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 coated steel pipe
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 structures, piling and other marine water.
Standard:
DIN 30670: Polyethylene coatings of steel pipes adn fittings.
DIN 30678: Polythylene coatiing of steel pipes and fittings.
SY/T0413-2002: Technical standard of polythelene coating for buried steel pipeline.
Types of anti-corrosion coating
Pipe corrosion types are divided into external corrosion and internal corrosion.
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 lateral wound polyethylene
coating, combined with three excellent performance, thereby significantly
improving the overall quality of corrosion of the pipe. Resistant to chemical
corrosion, cathodic stripping, resistance to mechanical damage performance.
3.coal tar 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.
