Cold Drawn Seamless Tube for Agricultural Machine
1) Production description:
Cold drawn tubes is well known as hydraulic cylinder tube in many industries, like in agriculture machine. This is because drawn tubing 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.
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 request.

3) Production process and details
The most common treatment methods for seamless tube are cold drawing and heat treatment .
The most popular steel grades of honed tubes 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.
Cold drawn tube is produced using our “Suitable to Hone" Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS).
Ths process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes.
Dooharvest is the biggest ST52 hydraulic cold drawn seamless tube,honed tubes manufacturer,are exposting over 20000t honed tubes one year .
