Honing tube, also known as hydraulic steel tube, is basically divided into fluid tube and oil steel tube on hydraulic system, cold drawn or cold rolled precision seamless steel tube. It is made of precision seamless steel tube with high dimensional accuracy and good surface finish. Mechanical structure or hydraulic equipment, a high-precision seamless steel pipe after cold drawing or cold rolling treatment. There is no oxide layer on the inner and outer walls of precision steel tubes, high precision, high finish, no deformation during cold bending, flaring, no cracking, etc. It is mainly used to produce pneumatic or hydraulic products.
