Stainless steel pipe is a kind of wire, made of stainless steel. Stainless steel pipe manufacturing process can be divided into: hot rolling (extrusion), cold rolling (pulling), thermal expansion of the basic categories of steel pipe.
Welded pipe in accordance with the manufacturing process can be divided into: straight seam welded steel pipe, submerged arc welded steel pipe, coil butt welded steel pipe, welded pipe thermal expansion pipe.
According to the shape of the steel pipe can be divided into square tube, rectangular tube, octagonal, hexagonal, D-shaped, pentagonal and other special-shaped steel pipe. Complex section steel pipe, double-concave steel pipe, five-tile plum-shaped steel pipe, conical steel pipe, corrugated steel pipe, melon-shaped steel pipe, double convex steel pipe and so on.
Classification according to use - Pipes for pipes, steel pipes for thermal equipment, steel pipes for machinery industry, steel pipes for petroleum, geological drilling, container steel pipes, steel pipes for chemical industry, special-purpose steel pipes, etc.
