3PE ordinary anti-corrosion spiral steel pipe thermal energy transmission pipeline supports customization

Description :

　　Anti corrosion steel pipe refers to a steel pipeline that has been processed and treated with anti-corrosion technology to effectively prevent or slow down the occurrence of chemical or electrochemical reactions and corrosion during transportation and use. According to statistical data in China, the direct economic losses caused by steel pipe corrosion in the country are over 280 billion yuan per year, and currently the global annual losses due to steel pipe corrosion are as high as 500 billion US dollars. Anti corrosion steel pipes can effectively prevent or slow down corrosion, extend the service life of steel pipes, and reduce the operating costs of steel pipes.

　　1. Classification by manufacturing process: (1) The manufacturing process of seamless steel pipes can be divided into several basic categories: hot rolling (extrusion), cold rolling (drawing), and hot expansion steel pipes. (2) Welded pipes can be divided into straight seam welded steel pipes, spiral welded steel pipes, plate coil butt welded steel pipes, and welded pipe hot expansion steel pipes according to manufacturing processes. Steel pipes can be classified by shape as follows: round pipe, square pipe, rectangular pipe, octagonal, hexagonal, D-shaped, pentagonal and other irregular shaped steel pipes, complex cross-section steel pipes, double concave steel pipes, five petal plum blossom shaped steel pipes, conical steel pipes, corrugated steel pipes, melon seed shaped steel pipes, double convex steel pipes, etc. Steel pipes can be classified by purpose as follows: steel pipes for pipelines, steel pipes for thermal equipment, steel pipes for mechanical industry, steel pipes for petroleum and geological drilling, steel pipes for containers, steel pipes for chemical industry, steel pipes for special purposes, etc.
