Seamless steel pipe plant for everyone analysis and introduction of the classification of seamless steel pipe four methods

(1) seamless steel pipe manufacturing process can be divided into: hot rolling (extrusion), cold rolling (pulling), thermal expansion of the basic types of steel pipe .
(2) The welded pipe can be divided into: straight seam welded steel pipe, submerged arc welded steel pipe, butt welded steel pipe, and welded pipe thermal expansion pipe according to the manufacturing process.
(3) According to the shape of 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-fractured plum-shaped steel pipe, conical steel pipe, corrugated steel pipe, melon-shaped steel pipe, double-convex steel pipe, etc.

(4) Classified by purpose - pipe steel pipe, thermal equipment steel pipe, machinery Industrial pipe, petroleum, geological drilling steel pipe, container steel pipe, chemical industry steel pipe, special purpose steel pipe, other seamless steel pipe classification method provided by Shandong Liaocheng Seamless Steel Tube Plant, information source.
