BS 6323 DIN 2391 Precision Steel Tube , BK BKS BKW Mechanical Steel Tubing for Hydraulic
Product Description:
Precision steel pipe is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision steel tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or The oil cylinder can be a seamless pipe or a welded pipe.
