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.
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?
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.
