PWHT by Induction Heating Method

I understand that in projects like Borouge, Ruwais the main construction contractor CCC is using and are prefering the induction heating.  As per my conversation the same as you have highlighted of the prefabrication spooling had been found to be more efficient and less time consuming and very acurate control of temperature, in comparision.

With regard to portability as per the contractor, they are using both portable and as well as fabrication shop stationed machine. It is available on lease by quite a no. of suppliers in the gulf region in particular. I havn't checked out the names of manufacturer nor the leasing agents, but can find out.

CCC also does have its own facility in the region in catering to various project sites of them. So in that sense it could be more efficient and cheaper solution on the run though the initial investment is high.

With regards,

Dear members

Please share your experience on the subject method for pipe welds
(PWHT to be carried at site), one of our client insisting for
Induction heating instead of PWHT by conventional resistance coil
heating.

tho' i have seen literature on this I need info on availability (first
hand experience) of the equipment, portability etc..

I understand it is faster but advantageous in mass production, and may
not be easier for site activities. i don't see any reason for this
method over resistance heating
