Honed Tubing Description

1、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.

2、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、Honed tube usually is produced by two main manufacturing process, which are honing process or skiving & roller burnishing process. The mother tube we usually use “Suitable To Hone” Cold Drawn Seamless Tubes. The process of the honed pipe is determined upon the dimension, mold available and the requirement of the customer.

Main applications of honed tubing

Honed tubing and SRB tubes (skived and roller burnished tubes) are mostly used as cylinder tube, such as hydraulic cylinder tube and pneumatic cylinder tubing, which are widely used for manufacturing and repairing hydraulic cylinders and pneumatic cylinders. As honed tube usually has very accuracy dimension tolerance and good surface smoothness, so this product is also used in applications where precision dimension or high smooth surface is need.
