Honing tube is a type of hydraulic steel tube that is made from cold-drawn precision seamless steel pipe. After acid pickling, phosphating, and other heat treatment, the steel pipe is process by cold-rolled or a cold-drawn machine to produce a hydraulic steel tube. The honing process is then used to hone the inner diameter to achieve a more precise inner hole size. Honing tubes have extremely high precision, generally controlled within the range of 0.02-0.05mm according to Chinese national standard GB3639 for cold-drawn or cold-rolled precision seamless steel tubes. XUD STEEL could produce hydraulic honed tubes according to standards from different countries, such as DIN 2391 EN 10305 JIS G3445, etc. Just contact XUDSTEEL to tell us your demand, our sales and engineers shall give you the best solution.
The allowable deviation of the inner diameter is 0.03mm, the roughness of the inner surface is normally Ra 0.2-0.8μm, and the straightness of the hydraulic steel tube is 0.3-1.5mm/m. Honing tubes are commonly used as cylinder barrels for hydraulic cylinders due to their high precision and durability.
There are several equivalent standards to GB3639 for cold-drawn or cold-rolled precision seamless steel tubes, including:
ASTM A519: This standard covers several grades of carbon and alloy steel mechanical tubing, including cold-drawn or cold-rolled precision seamless steel tubes.
EN 10305-1: This European standard specifies the technical delivery conditions for seamless cold-drawn steel tubes of circular cross-section for precision applications.
DIN 2391: This German standard specifies the technical delivery conditions for seamless precision steel tubes, including cold-drawn or cold-rolled precision seamless steel tubes.
JIS G3445: This Japanese standard specifies the carbon steel tubes, which are used for machine structural purposes, including cold-drawn or cold-rolled precision seamless steel tubes.
