Bright Annealing Seamless E235 Precision Steel Tube

Din 2391 High Pressure Bright Annealing Seamless Precision E235 Steel Tube

1. DIN2391 high precision bright seamless steel pipe
Made of Baosteel's high-quality carbon steel material, after precise drawing, non-oxidative bright heat treatment (NBK state), non-destructive testing, the inner hole of the steel pipe is subjected to high-pressure washing and pickling, the inner and outer walls of the steel pipe are treated with anti-rust oil, and both ends are sealed as Dust-proof treatment.
The steel pipe produced has high precision and good finish, and there is no oxide layer on the inner and outer walls of the steel pipe. Mechanical properties can be bent at any angle without deformation. It is mainly used to prepare steel pipes in the oil circuit of hydraulic systems, also called hard piping in hydraulic systems, and precision steel pipes for automobiles.

2. DIN2391 high-precision black phosphating steel pipe
Based on DIN2391 high-precision bright seamless steel pipe, the inner and outer walls of the bright precision steel pipe are phosphated with the dilution formula of phosphating agent, and a black protective film is formed on the inner and outer walls of the steel pipe to protect the steel pipe from rust. Black phosphating steel pipe is shiny in black, good color and strong rust resistance.​​
High-precision black phosphating steel pipe is mainly used for piping in hydraulic system, and it is more ideal to use with ferrule (steel pipe) joint.

3. DIN2391 high-precision precision galvanized steel pipe
The high-precision bright seamless steel pipe is used to electro-galvanize it, and the inner and outer walls of the steel pipe are plated with yellow zinc (color zinc), white zinc, and passivation treatment. The length of the galvanized steel pipe can be within 6 meters.
Mainly used in automobile, military, aircraft, agricultural and forestry machinery, construction machinery, railway vehicles and other industries
