China Hydraulic Cylinder honed tube manufacture and supplier
1) Production description:
Honed tube is well known as hydraulic cylinder tube in many industries. This is because honed tubes are the most important materials of manufacturing hydraulic cylinders. And as this kind of tubing is usually honed in tube inside diameter, it is known as honed ID tubing also.
Steel honed tubing is made of seamless cold drawn steel pipes, the cold drawn tubes can be produced according to most popular international standards such as DIN 2391, EN 10216-2, ASTM A513-5, A 519, GB/T 3639 etc. on customer's

3) Production process and details
The most common treatment methods for hydraulic and pneumatic cylinder tubes are cold drawing and heat treatment .
The most popular steel grades of honed cylinder tubing is SAE 1020, we also supplier honed tubes in SAE 1026, St 52 and other steel grades such as St35, ST 52.4, St 37.4, E255, E215, etc. on customers' request.
Honed tube is produced using our “Suitable to Hone” Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS).
The honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes.
