Dear Experts,
Good Morning,
We are having our own project to build an offshore jacket for a depth of 15 to 20 meter water depth. For this project we are in the stage to order the material (PIPE) from the Steel Mill. In order to start the process the mill is asking for the SPEC of PWHT. So can anyone able confirm what should be the Holding temp / time / No of cycle / Stress relieving cycle required for PWHT.
| Sl.No | Material Size | Grade | Remark |
| 1 | 24" Pipe x 25mm wall thick | API 5L Gr.X52N PSL2 | Normalizing Steel |
| 2 | 30" Pipe x 30 mm wall thick | API 2H GR.50 +(Z35) | Normalizing Steel |
| 3 | 20" Pipe x 25mm wall thick | API 5L Gr.X52M PSL2 | TMCP Steel |
Regards
Thandesh
