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.
Materials:
The most popular material of our honed tubes is carbon steel grade SAE 1020. And we also produce honed cylinder tubes in other materials such as SAE 1026, E355 and ST52.3, stainless steel and so on.
Size Range:
As the leading hydraulic cylinder honed tube suppliers, most of the factories can produce honed cylinder tubes in a wide range of metric sizes and imperial sizes. Here below is the typical size range of honed tubes.
Inside Diameter 32mm to 600mm; Imperial sizes equally.
Normally honed tubing is supplied in fixed length or random lengths, the max. Length of honed tube is 14 meters, sometimes even longer for special application purpose.
