Seamless steel pipe is a kind of perforated by the whole round steel, and the steel pipe without weld on the surface . It is a kind of economic section steel,according to the different cross sectional area shape can be divided into round pipe and special-shaped pipe. Using seamless steel pipe to manufacturering parts can improve the material utilization rate, simplify the manufacturing process, and save the material and processing time. Widely used in manufacturing structural parts and mechanical parts etc.

2.Honing seamless hydraulic cylinder tube processing
Raw Materia l→ Acid cleaning → Parkerizing →Cold-drawn →stress relieving→ leveling→ saw off not good parts→ honing→ inspection→ packing
3.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
4.Packing and delivery
1. Small OD: In hexagonal bundle with steel strips
