Honed tube is usually a CDS (Cold drawn seamless) steel tube or DOM (Drawn Over Mandrel) steel tube with inside diameter honed or skived &roller burnished, so honed tubing is with extremely precise ID dimensions and smoothly ID surface.

Honed tubes are broadly utilized to produce and repair hydraulic cylinders and pneumatic cylinders. So in many fields, the honed tube is called cylinder tube also.

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.

Honed tubes are widely used in hydraulic systems such as various oil cylinders, air cylinders, and hydraulic cylinders due to their high-precision inner wall and good mechanical properties. Honed tubes play an important role in engineering machinery, automobiles, ships, aerospace, and other fields. For example, in engineering machinery such as excavators and loaders, honed tubes are used in the manufacture of oil cylinders and are subjected to huge pressure and impact, in automobile manufacturing, honed tubes are used in key parts such as engines and brake systems to ensure the safety and stable operation of automobiles.
