ST35 C20 CK45 4~70mm Diameter NBK GBK State High Precision High Finish Hydraulic Cylinder Tube
Hydraulic steel tubes are basically divided into fluid tubes and oil steel barrel tubes used on hydraulic systems, also known as honed tubes, while cold drawn or cold rolled precision seamless steel tubes also contain hydraulic steel tubes.Hydraulic system on the fluid tube in the domestic national standard close to the standard is GB3639-83. hydraulic steel pipe introduction: hydraulic equipment of high dimensional accuracy and good surface finish cold-drawn or cold-rolled precision seamless steel pipe. The selection of precision seamless steel tube manufacturing mechanical structures or hydraulic equipment, etc., precision steel tube through cold-drawn or cold-rolled treatment after a high precision seamless steel tube. As the precision steel tube inside and outside the wall without oxidation layer, bear high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other points, so mainly used to produce pneumatic or hydraulic products.
