2. Standard Reference for seamless precision tube and erw precision steel tubes:

EN10305-2 <Welded cold drawn tubes>
EN10305-4 <Seamless cold drawn tubes for hydraulic and pneumatic power systems>
EN10305-6 <Welded cold drawn tubes for hydraulic and pneumatic power systems>
JIS-G3445 <Carbon steel tubes for Machine Structural Purpose>
DIN2393 <Welded precision steel tubes>
GB/T8713 <Precision ID seamless tubes for hydropneumatic purposes>
GB/T3639 <Cold-rolled and cold drawn precision seamless steel tubes>

3. Production process for precision steel pipe​:
DIN series tubes, cold drawn and bright annealed precision seamless steel tube is to be phosphated or gavlvanized upon customer's request.

The phosphorization is realized with the imported chemical fluid to form a black film.

The antirust oil is absorbed by means of the micropore on the film to prevent the tubes from getting rust.


4. Main Application of seamless precision tube:
For auto industry, machinery use, oil cylinder, motorcycle shock absorber.
