Hydraulic steel tubes are basically divided into fluid tubes and oil steel barrel tubes used on hydraulic systems, also known as hydraulic honed tubes, while cold-drawn or cold-rolled precision seamless steel tubes also contain hydraulic steel tubes.
Hydraulic honed pipe:By cold rolled precision seamless steel pipe is made of seamless steel tube finished tube or seamless tube barren tube, after pickling, phosphating, saponification treatment, and then rolled by cold tube rolling machine to make hydraulic steel pipe. Hydraulic steel pipe precision is extremely high generally can be controlled within the range of 0. 02-0. 05MM, the standard is: GB3639-83, the allowable deviation of the inner warp is 0.03mm, the inner surface roughness: Ra 0.2~0.8μm, hydraulic steel pipe straightness: 0.3~1.5mm/m, dedicated to do the cylinder diameter of oil steel.
