Established in December 1992, Yantai Xinpeng Steel Pipe Co., Ltd. has been specialized in this line for more than 20 years.

During the past 20 years, Xinpeng produces various kinds of seamless steel pipe, which can be widely used for hydraulic cylinder for automobile,engineering machinery, excavator, forklifts etc.

Xinpeng are equipped with JLB250T hydraulic cold drawn set, LD120 cold rolling set, annealing furnace,strong honed machine, polishing machine, lathe, saws CNC skived and roller burnished machine, kinds of testing machine.Strictly comply with the ISO9001 System, assure the best quality of the products.

Production

(1)cold drawn/rolled pipes

Grade: 20#  45#  Q345B  Q345D  25Mn  27SiMn  E355  SAE1026

Standard: GB/T8713  GB/T3639  DIN2391  EN10305  ASTMA519

Range: 30-300mm

Length: 11m(max)

The cold process can improve the machanical property of the pipes and offer better tolerance.

(2)SRB&Honed Tube

ID Tolerance: H8  H9

ID Roughness: RA0.4micron(max)

Length: 6m(max)

This process can improve the roughness of the inner tube with roughness 0.2-0.4um.

The difference between precision steel pipe and seamless pipe?

1. the seamless steel tube with obvious 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.

Process

Equipped with JLB250T hydraulic cold drawn set, LD120 cold rolling set, annealing furnace, strong honed machine, polishing machine, lathe, saws CNC skived and roller burnished machine, kinds of testing machine.

Packaing

1. bundle packing

2. marking as per customer's requests

3. paint on the pipe as per customer request

4. pipe caps as customer request

Application
