Ready To Honed Tube Hydraulic Tube Suppliers
Product Description:
Hydraulic cylinder tube also named honed tube or cold-drawn honed seamless cylinder tube.It is the most important material used for hydraulic cylinder manufacturing.
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 request.
Cold-drawn honed seamless cylinder tube production processing:
Raw Materia - Acid cleaning - Parkerizing - Cold-drawn - stress relieving - leveling - Saw off reject parts - Honing - Anti oil coating - Packing
Item | Honed Tube |
Standard | DIN2391, EN10305. |
Steel Graded | ST52, STKM13C,ST45 , E355 |
Inner Diameter | 20mm-1500mm |
Outer Diameter | 50-400mm |
Length | max 16m |
Straightness | ≤ 0.5/1000 |
Roughness | 0.2-0.4 um |
ID Tolerance | H8 |
Condition of Delivery
1. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee
4. BKW(+LC)
after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain
limits cold deformation(bending, flaring)
5. BKS(+SR)
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate
processing again
