Carbon steel pipe is the most commonly and widely used in the gas project field. The large diameter coated steel pipes are widely used in tap water, natural gas, petroleum, chemical, pharmaceutical, telecommunications, electricity, large diameter steel marine engineering field generally less than the outer diameter of the tubes 89 are collectively referred to as small-diameter steel pipe.
Steel Pipe, Seamless Steel Pipe, Steel Tube manufacturer / supplier in China, offering S20c hot rolled seamless carbon steel pipe for machinery framePrecision Seamless Steel Pipe Large Stocks, Stkm11A Stkm12A Stkm13c Seamless Steel Pipe by Hot Rolled with Carbon Seamless Pipe From Liaocheng, Welded Pipes Galvanized Steel Pipe Steel Pipe and so on.(plate) Cold-rolled nitriding treatment of seamless steel pipe(steel) The cold rolling of seamless tube and steel tube transforms martensite into seamless tube and steel tube before the rolled piece enters the finishing rolling extruder. Rough rolling is still carried out under full martensite conditions. The nitriding treatment method of seamless steel pipe mainly adopts a nitriding furnace.
