Seamless Steel Pipe Uses
1, seamless steel pipe has a hollow cross-section, used in large quantities as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water and certain solid materials. Compared with round steel and other solid steel, steel pipe is a kind of economic cross-section steel when the bending and torsion strength is the same, the weight is lighter.
2, widely used in the manufacture of structural and mechanical parts, such as oil drilling rods, automobile drive shafts, bicycle frames and steel scaffolding used in building construction, etc. The use of seamless steel pipe to manufacture annular parts can improve the material utilisation rate, simplify the manufacturing process, save materials and machining man-hours, and it has been widely used in the manufacture of steel pipe.
Seamless steel pipe material
Seamless steel pipe for general use is made of 10, 20, 30, 35, 45 and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other bonded steel hot-rolled or cold-rolled. 10, 20 and other low-carbon steel seamless pipe is mainly used for fluid transport pipelines. 45, 40Cr and other medium-carbon steel made of seamless steel pipe is used to Manufacture of mechanical parts, such as automobiles, tractor parts.
