Precision tubes are seamless steel pipes produced through cold drawing or cold rolling processes, featuring high precision and brightness. Their inner and outer diameters can be as small as 0.2mm. While ensuring bending and torsional strength, they are also lightweight, making them widely used in the manufacturing of precision mechanical parts and engineering structures. They are also commonly used in the production of various conventional firearms, gun barrels, shells, and bearings.Its features include a smaller outer diameter, high precision suitable for small batch production, and cold drawn finished products with high precision; excellent surface quality, more complex cross-sectional area of the steel pipe; superior steel pipe properties with denser metal.
