Which Is More Precise For Honing And Honing?

- Aug 31, 2019-

St52 Honed Pipe: The cold-rolled precision seamless steel pipe is made of seamless steel pipe finished pipe or seamless pipe waste pipe, pickled, phosphatized, saponified, and then rolled into a hydraulic steel pipe by cold rolling mill. The precision of hydraulic steel pipe can be controlled within the range of 0. 02-0. 05MM. The standard is: GB3639-83, the internal tolerance is 0.03mm, the inner surface roughness is Ra 0.2~0.8μm, and the hydraulic steel pipe is straight. Degree: 0.3 ~ 1.5mm / m, dedicated to the diameter of the oil steel. The standard for the fluid pipe on the hydraulic system to be close to the domestic national standard is GB3639-83.

 

Introduction of hydraulic steel pipe: cold drawn or cold rolled precision seamless steel pipe with high dimensional accuracy and good surface finish. The use of precision seamless steel tubes to manufacture mechanical structures or hydraulic equipment, precision steel tubes through a cold drawn or cold rolled after processing a high-precision seamless steel pipe. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic products.
