Product name :
Hydraulic Gas Cylinder Galvanized Steel Pipe
Detailed description
Our main porduct ： Hydraulic Cylinder Tube
Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.
Processing : cold drawn cold rolled honed SRB Burnish
ID : 30--250mm
Length : ≤10m
ID Tolerance : H8 H9
Tolerance on Wall Thickness:
Diameter: >40 0.2mm
Diameter: 40
Diameter >100 0.5mm
Surface Roughness : Ra 0.02—0.4μm
Delivery condition of hydraulic cylinder tube:
1.NBK(+N) of hydraulic tube
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A) of hydraulic cylinder tube
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C) of honed tube
the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee
4. BKW(+LC) of hydraulic cylinder tube
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) of honed tube
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
Other different tube ：
1.Seamless steel tube
Widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can also offer ascustomized seamless steel tube.
2.cold drawn/rolled steel tube
Grade: 20# 45# 16Mn 25Mn 27SiMn E355 SAE1026
Standard: GB/T8713 GB/T3639 DIN2391 EN10305 ASTMA519
Range: 30-300mm
Length: 11m(max)
The cold process can change the thickness of tube to meet client's request and offer better mechanical property.
3. SRB tube
used in Elevatorbuffer and Hydraulic Cylinder .This kind tube have a better roughness inner the tube, ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Range: ID 50-250mm and Length can work at most 6M.

Galvanized Steel Pipe can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements.Hydraulic Gas Cylinder Galvanized Steel Pipe has been used used for water-supply pipes or as a strong tubing for outdoor applications.
USHDJ
Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. Hydraulic Gas Cylinder Galvanized Steel Pipe is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.Hydraulic Gas Cylinder Galvanized Steel Pipe is covered with a zinc material to make the steel pipe more resistant to corrosion.
