Anti-corrosion steel pipes are classified according to different ways
 
   Anti-corrosion steel pipe refers to the steel pipeline which can effectively prevent or slow down the corrosion phenomenon by chemical or electrochemical reaction during transportation and use after anti-corrosion process processing. According to China's statistics, the annual domestic steel pipe corrosion direct economic loss of more than 280 billion, the current global annual loss of up to $ 500 billion due to steel pipe corrosion. Anti-corrosion steel pipe can effectively prevent or slow down corrosion to extend the service life of steel pipe and reduce the cost of steel pipe operation.
Anti-corrosion steel pipe according to different ways of classification

Anti-corrosion steel pipe according to the manufacturing process classification.
 
(1) seamless steel pipe manufacturing process can be divided into: hot-rolled (extrusion), cold-rolled (drawing), hot-expanded steel pipe the basic categories.
 
(2) welded pipe according to the manufacturing process can be divided into: straight seam welded steel pipe, spiral welded steel pipe, plate and coil butt welded steel pipe, welded pipe hot expanded steel pipe.
 
Anti-corrosion steel pipe according to the shape of the classification.
 
Steel pipe according to the shape can be divided into: round, square, rectangular, octagonal, hexagonal, D-shaped, pentagonal and other shaped steel pipe, complex section of steel pipe, double concave steel pipe, five plum-shaped steel pipe, conical steel pipe, corrugated steel pipe, melon-shaped steel pipe, double convex steel pipe, etc.
 
Anti-corrosion steel pipe classification by use.
 
Anti-corrosion steel pipe can be divided into: steel pipe for pipeline, steel pipe for thermal equipment, steel pipe for mechanical industry, steel pipe for petroleum, geological drilling, container steel pipe, steel pipe for chemical industry, special-purpose steel pipe, etc. by application.
