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.
