Main product

1 Hydraulic Cylinder Tube

Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. We can work and get the mechanical property of the clients need.

2. SRB tube

Directly used in Elevatorbuffer and Hydraulic Cylinder .This kind tube have a better inner roughness , ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Length can work at most 6M.

3. Cold finished tube

Widely Used. Processing range 30-300mm, biggest length is 11M.

The difference between precision steel pipe and seamless pipe?

1. the seamless steel tube with obvioue difference is that dimensional accuracy, can be up to 0.1mm.

2. high precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.

3.Superior surface finish

4.Dimensional accuracy and excellent micro-structure uniformity

Process

Equipment

Xinpeng is equipped with JLB250T hydraulic drawn set, LD120 cold rolling set, annealled furnace, honed machine, SRB machine, polishing machine, lathe and some testing machine, making sure to meet every client's request with superior quality.

Packaging & Shipping

Packaging: standard packing with plastic foam or with cartons or as client's request

Shipping: arranging shipment within 20-30 days after receiving order or as client's request

Delivery condition

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
