Anticorrosive steel pipe is made of steel pipe as anticorrosive coating, according to different classification standards, anticorrosive steel pipe has different types. The following are anti-corrosion steel pipes classified according to different standards:
Classification by manufacturing process:
Seamless steel pipe: hot rolled (extruded), cold rolled (drawn), hot expanded steel pipe.
Welded pipe: straight seam welded steel pipe, spiral welded steel pipe, sheet butt welded steel pipe, welded pipe thermal expansion steel pipe.
Classification by shape: round pipe, square pipe, rectangular pipe, octagonal, hexagonal, D-shaped, pentagonal and other special-shaped steel pipe, complex section steel pipe, double-concave steel pipe, five-valve plum pipe, conical steel pipe, corrugated steel pipe, melon seed steel pipe, double convex steel pipe and so on.
Classification by use: pipe steel pipe, thermal equipment steel pipe, mechanical industry steel pipe, petroleum, geological drilling steel pipe, container steel pipe, chemical industry steel pipe, special purpose steel pipe, etc.
Classified according to the anti-corrosion technology done:
IPN8710 anti-corrosion: Specially used for food, drinking water and other contact equipment, water distribution pipeline, drinking water tank surface anti-corrosion.
Epoxy powder anticorrosive steel pipe (also known as coated plastic steel pipe) : mainly used for water transmission, drainage, gas extraction and other pipelines, long life generally available 30-50 years.
3PE anticorrosive steel pipe (also known as three-layer polyethylene anticorrosive steel pipe) : mainly used in oil and gas pipelines, in recent years, pipe jacking construction, drainage engineering has also been a good application.
Brush oil cloth anticorrosive steel pipe (also known as epoxy coal asphalt anticorrosive steel pipe) : mainly used in drainage projects, rain pollution discharge projects, sewage treatment projects, industrial water supply projects.
