Precision Bright Tube

Short Description:

Precision bright tube is a high-precision steel tube material processed by fine drawing or cold rolling. Because there is no oxide layer on the inner and outer walls of the precision bright tube, high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, etc., it is mainly used to produce pneumatic or hydraulic components, such as cylinders or The oil cylinder can be a seamless tube or a welded tube. The chemical composition of the precision bright tube includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.

Process introduction

High-quality carbon steel, fine-rolled, non-oxidizing bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and subjected to high-pressure washing, the rust-proof oil on the steel pipe is used for rust-proof treatment, and both ends are sealed for dust-proof treatment.

main feature

The inner and outer walls of the steel pipe have high precision and high smoothness. After heat treatment, the steel pipe has no oxide layer, and the inner wall has high cleanliness. . Steel pipe color: bright white with high metallic luster.

The main purpose

Automobiles, machinery parts and other machinery that have high requirements on the precision and smoothness of steel pipes. The users of precision steel pipes are not only users who have relatively high requirements for precision and smoothness. Because the precision of precision bright pipes is high and the tolerance can be maintained at 2--8 filaments, many machining users will save labor, material, and time loss. Seamless steel tubes or round steel are slowly being transformed into precision bright tubes.
