Precision tube is a high-precision, high-brightness seamless steel tube produced by cold drawing or cold rolling. Its inner and outer diameters can be accurate to within 0.2mm. While ensuring bending and torsional strength, it is light in weight, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, bearings, etc.

Commonly used materials are 10#, 20#, 35#, 45#, 20cr, 40Cr, 20CrMo, 16mn, 27simn, 304, 201, 310s, high-quality carbon structural steel. As a kind of high-quality steel pipe, precision pipe has many advantages: smaller outer diameter, high precision and small batch production, high precision of cold-drawn finished product, good surface quality, more complex cross-sectional area of steel pipe, superior performance of steel pipe, and relatively dense metal.

Precision tubes are playing an increasingly important role in human production and life, and are closely related to people's lives.
