Seamless steel pipes in large calibers for high(low and middium)pressure boilers and petrochemical industry
Description:
Carbon steel pipe is divided into hot rolling and cold rolling (drawing) steel pipe.
Hot rolled carbon steel pipe, low, medium pressure boiler steel tube, high pressure boiler tube, alloy steel tube, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe, etc.
Cold-rolled (dial) carbon steel pipe in addition to general steel tube, low medium pressure boiler pipe, high pressure boiler tube, alloy steel, stainless steel pipe, oil cracking pipe, steel pipe, other include carbon thin wall steel tube, alloy thin wall steel pipes, thin-walled stainless steel tube, steel tube.Generally greater than 32 mm hot rolled seamless steel tube diameter, wall thickness 2.5 75 mm, to 6 mm cold rolled seamless steel tube diameter, wall thickness to 0.25 mm, to 5 mm thin wall pipe diameter, wall thickness less than 0.25 mm, cold than hot rolled high dimensional accuracy.
