Local post weld heat treatment (PWHT) is a stress release process by heating the welded zone after the workpiece is welded, which is an indispensable step to ensure the welding quality. Usually, this kind of post weld heat treatment procedure/processs is done with the induction heating machine. Take JKZ's induction heating devices as examples. These devices will normally first heat the workpiece at the temperature of 100-150 degrees/hour and they will gradually reach the target temperature at 650-780 degrees according to different metal material features. All the processes will be completed perfectly in accordacne with the pre-set heating time and pwht recorder temperature. The temperature recorder will record the temperature curve and feedback the data to the control system. Due to the need for strict requirements of the heating time and temperature control, the high degree of automation of induction heating equipment have successfully made itself locate at a very important position in all kinds of PWHT post weld heat treatment machine. In addition to general equipment, JKZ also specializes in the post-weld heat treatment for pipes, plates, tanks and large-size heterogeneous workpieces. Two specially designed air-cooled induction heating systems can be flexibly custmoized according to your choices.
Features of Induction Post Weld Heat Treatment
1.Wide and even heating zone
The width is sufficient to cover the uniform heating zone of the post-weld heat treatment specified by ASME.
2.High-precision temperature control
Frequency conversion control power supply can realize precise heating/heat preservation/cooling steps.
3.High security
Unlike annealing of resistance heating elements, non-heated induction coils ensure a high degree of safety.
4.Easy installation
One-button operation coil (the built-in coil piece is placed around the pipe), which is easier to fix and disassemble than the induction coil wound on the pipe. |
