Description
What is the material of honed tube?
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.
What size is a hone tube?
Non standard tube supply
What is a honed tube used for?
How to make hydraulic tube
The tubes surface finishing is NBK, where the tubes are phosphate and normalized which provides corrosion resistance. It is oiled inside and outside. Normalize process creates tougher metal product. During normalizing, metals will be heated at a high temperature, and it allowed to naturally cool back down to room temperature by exposure after heating. Metals that have been through this process are more formable, harder and ductile.
Pressure ratings of hydraulic tube
Allowable working pressures are calculated using as per DIN 2413 at normal temperature. The yield and tensile stress values utilize to determine the maximum allowable running pressure and wall thickness required. The tubes and pipes are delivered the actual yield and tensile stress values are verified from the true copy material certificates. Pressure reduction factors at various temperatures show below:

Explanation
|
|
Cold-finished/hard (cold-finished as-drawn)
|
BK
|
No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
|
|
Cold-finished/soft (lightly cold-worked)
|
BKW
|
After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be
cold-formed (e.g. bent, expanded) within certain limits. |
|
Annealed
|
GBK
|
After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
|
|
Normalized
|
NBK
|
The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.
