| Abstract: | During construction of the second phase project of Ninghai power plant 1 000 MW ultra-supercritical boiler unit,induction heating equipment was used for experiment on welding heat treatment technique,which well solved the problem of temperature difference between inner and outer wall occurring in the process of welding preheat and post-welding heat treatment of the SA335-P92 steel tube,significantly improved the welding heat treatment quality.This experiment method can be used as a reference by other project in welding preheat and post-welding heat treatment for ultra-supercritical boiler unit. |
| Keywords: | ultra-supercritical unit new type heat-resistant steel P92 steel weld welding heat treatment induction heat equipment |
