The features of precision tube:
1. exact diameter than seamless pipe
2. High precision of carbon tube can be done with tolerance H9, H10
3. Cold finished makes high precision, good roughness, and nice
quality
4. Honed tube or SRB tube can be used for hydraulic cylinder
directly
5. High mechanical property better than seamless pipe
What we can provide are honed seamless tube pipe, honed tube pipe, seamless pipe, carbon tube, cold drawn tube, cold rolled tube, hydraulic cylinder tube, honed tube......
seamless tube, honed tube, hydraulic tube, carbon steel pipe, cold drawn pipe, cold rolled pipe, and so on.
1.Seamless steel tube and carbon tube, seamless pipe
Widely used in the hydraulic cylinder of the heavy machinery,
Cranes, excavator also forklifts. Material is various, mainly
STKM-13CT, ST52, CK45 and AISI 1020. We can also offer as
customized seamless steel tube.
2.cold drawn steel tube/cold rolled steel tube, cold drawn pipe,
cold rolled pipe, cold drawn tube, cold rolled tube

Delivery condition:
The tubes can be produced in the following delivery conditions:
BK (+C) Cold finished/hard (cold finished as drawn).
No heat treatment after the last cold forming process.
BKW (+LC) Cold finished/soft (lightly cold worked)
After the last heat treatment there is a light finishing pass (cold drawing).
BKS (+SR) Cold finished/stress relieve annealed.
After the final cold forming process the tubes are stress relieve annealed.
GBK (+A) Annealed.
After the final cold forming process the tubes are annealed in a controlled atmosphere.
NBK (+N) Normalized. (Mainly focus on)
After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere
