The blank used for the welded steel pipe is steel plate or strip steel. 2. Seamless steel pipe: A steel pipe made of a single piece of metal with no seams on the surface is called a seamless steel pipe. B. Different uses 1. Welded steel pipe: It can be used as water gas pipe, etc., large-diameter straight seam welded pipe is used for high-pressure oil and gas transportation, etc.; spiral welded pipe is used for oil and gas transportation, pipe piles, bridge piers, etc. 2. Seamless steel pipes: used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
