Product Description

Precision tube is a high-precision, high-brightness seamless steel tube produced through cold drawing or cold rolling processes. Its inner and outer diameter dimensions can be accurate to within 0.2mm. It ensures bending and torsional strength while being light in weight, so it is widely used in manufacturing precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, bearings, etc.
Precision steel pipe is a high-precision cold-drawn seamless steel pipe with the characteristics of high accuracy in inner and outer diameter dimensions, wall thickness, good surface finish, smooth inner and outer surfaces, and no impact burrs. Precision steel pipes are usually made of carbon steel, alloy steel, stainless steel and other materials, and are widely used in manufacturing machines, automobiles, aerospace, health equipment and other fields.
