Cold-drawn steel pipe is a kind of steel pipe, that is, it is classified according to the different production process, different from hot rolled (expanded) pipe. In the process of expanding the raw tube blank or raw tube through many times of cold drawing processing, usually in 0.5 ~ 100T single chain or double chain cold drawing machine. Cold rolled (dial) steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, mechanical processing pipe, thick wall pipe, small diameter with inner mold cold drawing pipe other steel pipe, also includes carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, special-shaped steel pipe.
