Precision seamless steel Pipe/tube is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipe have no oxide layer, bear high pressure and no leakage, high precision, high smoothness, cold bending without deformation, expansion It is mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded pipes. Compared with solid steels such as round steel, seamless steel pipes are lighter in flexural and torsional strength when the bending and torsion strength is the same. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and machinery.

Welded steel pipe refers to steel pipes with seams on the surface that are welded by steel strips or steel plates that are bent and deformed into round or square shapes. The blanks used for welded steel pipes are steel plates or strip steels. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are increasing, and seamless steel pipes are replaced in more and more fields. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes

High-frequency welded pipes are generally straight-slit, but straight-slit welded steel pipes are not necessarily high-frequency welded. The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the high-frequency current after the hot-rolled coil plate is formed by the molding machine, and the edge of the tube blank is heated and melted, and pressure welding is performed under the action of the pressing roller to realize the production. The high-frequency resistance welded steel pipe is different from the ordinary welded pipe welding process. The weld is made of the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe. The surface is smooth, high precision, low cost, and has low weld seam height, which is beneficial to the coating of 3PE anti-corrosion coating.
The hot expanded seamless steel pipe is relatively low density but the contraction of the strong seamless steel pipe can be referred to as thermal expansion. The roughing finishing process for expanding the diameter of a pipe by a cross-rolling method or a drawing method. Steel pipe thickening in a short period can produce non-standard and special types of seamless tubes with low-cost and high production efficiency, the current international developments in the field of tube rolling.
