The quilted steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Seamless Steel Pipes Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., Hydraulic Cylinder Tube they are mainly used to produce pneumatic or hydraulic components, such as cylinders or Cylinder, can be seamless tube.Other similar products are: Steel Pipe, Structural Steel Pipe, Weld Steel Pipe , Boiler Steel Pipe Decrisption Product Name Hydraulic Parts Using ST52 Honed Seamless Steel Pipes Standard ST52 Material ST52 Production Process Hot Rolled Tolerance OD :+/-1% ,WT:+/-1% ,Length:+/-5cm…
