The manufacturing process of seamless steel pipe production can be divided into four basic methods: cold drawing, cold rolling, and thermal expansion. The materials of steel pipes are #, Steel pipes made of low alloy steel pipes such as, r, r, r, r, etc. are collectively called alloy steel pipes. According to the purpose, it is divided into structural seamless steel pipes (/-) seamless steel pipes for fluid transportation (/-) low and medium pressure boiler seamless steel pipes (-) high-pressure seamless steel pipes for boilers (-) high-pressure seamless steel pipes for fertilizer equipment. (-) Seamless steel pipe for geological brick exploration (-) Seamless steel pipe for petroleum brick exploration (-) Seamless steel pipe for petroleum cracking (-) Seamless steel pipe for ships (-) Cold-drawn and cold-rolled precision seamless steel pipe (-) ) Steel pipes for oil and gas industry pipeline transportation systems (/). The expression method of seamless steel pipe is outer diameter * wall thickness.
Calculation formula
Seamless steel pipe weight per meter =.*(-)
Symbol meaning = outer diameter = wall thickness
Seamless steel pipe price per meter = (outer diameter - wall Thickness)*Wall thickness*.*Price per kilogram
