Seamless steel pipes for low and medium pressure boiler, high pressure boiler, ship-building,Liquid service, petroleum cracking, chemical fertilizer equipment, Drawing-oil-equipment and structure purposes. |
| Business scope |
DIN series cold drawn precision seamless steel tubes DIN series cold rolled precision seamless steel tubes Related coated and galvanized steel tubes Rustproof phosphyorylated tube |
| Main characteric |
No Oxidation Layer on the outer and inner walls; No Leakage under high pressure; No Crake under flating and flattening; No distortion after cold bending; High precision high cleanness; Excellent brightness cold drawn and hot finished Superior performance for high pressure and temperature uses Black finish and hot dip galvanized Excellent corrosion resistance |
Delivery condition:
| Designation | Symbol | Description |
| Cold finished (hard) | BK | Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation. |
| Cold finished (soft) | BKW | The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming. (e.g. bending, expanding). |
| Cold finished and stress-relieved | BKS | Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree. |
| Annealed | GBK | The last cold forming process is followed by annealing in a controlled atmosphere. |
| Normalized | NBK | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
All other tubes applicable for boiler and heat exchanger tube we can produce ,
