) The manufacturing process of seamless steel pipe production can It is divided into four basic methods: cold drawing, cold rolling and hot expansion. The material of the steel pipe is called ordinary steel pipe. The material between ordinary steel pipe and alloy steel pipe is called low alloy steel pipe. The steel pipes with equal materials are collectively called alloy steel pipe. According to the purpose, it is divided into structural seamless steel pipes (/) seamless steel pipes for transporting fluids (/) seamless steel pipes for low and medium pressure boilers () high-pressure seamless steel pipes for boilers () high-pressure seamless steel pipes for fertilizer equipment () geotiles Seamless steel pipes for exploration () Seamless steel pipes for petroleum brick exploration, Seamless steel pipes for petroleum cracking () Seamless steel pipes for ships, Cold-drawn and cold-rolled precision seamless steel pipes () 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
