The cold working methods of steel pipes mainly include cold drawing and cold rolling. The raw materials of cold-rolled steel pipes can be hot-rolled seamless steel pipes or welded pipes. The common characteristics of the cold working method of steel pipes are high dimensional accuracy and good surface roughness. It can produce very thin (up to 0.05~0.01mm) thin-walled tubes and very thin (up to 0.3~0.1 mm in diameter) capillaries. Seamless steel pipe is a kind of pipe with hollow section, which is widely used to transport fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is light in weight when its bending and torsional strength is the same. It is a kind of economic section steel
