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. Generally, the production process of seamless steel pipe can be divided into cold rolling and hot rolling. The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe. The wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe
Boiler Steel Pipe is a kind of circular Steel Pipe with hollow section. Compared with solid steel such as round steel bar, Hot rolled seamless steel pipes has the same bending and torsional strength and light weight. It is an economic section steel. It is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring parts with Structural Steel Pipe can improve...

The Carbon Structural Tube is a hollow section customized carbon steel tube with no welds from beginning to end. When the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Using Carbon Structural Tube to make square parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing time. The ASTM A106 Carbon Structural Tube has a hollow section and is used for Pipelines for conveying oil, natural...
