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. |
Applications:
1,For evaporator, heat exchangers, condensers, heat transfer equipment and similar pipes.
2,Widely used in the mechanical treatment field, petrochemical industry, transport and construction field
3,Ordinary structural purposes and mechanic structural purposes, for example in construction field, fulcrum bearing etc;
4,The transportation of fluids in the projects and big equipments, for example transport of water, oil, gas etc
5,Can be used in low and medium pressure boiler for the transportation of fluids, for example steam tube, big smoke tube, small smoke tube, generating tube etc
All other tubes applicable for boiler and heat exchanger tube we can produce ,
