Products

(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 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
