Vinod,
I would say that was a wise discussion. Although I had dropped a few lines on safe welding practices as per API -510, later after browsing through API-579(Section-11, Assessment of Fire Damage ), I realized that a lot more things are desired for proper assessment for any fire damage , then only any welding/ refurbishing should be thought of.
It would be a good idea to get some heads up from API-579 on such damages in future . There're are some typical examples on assessment of fire damages of various plants and equipments in this API/ASME book.
Thanks.

Dear All,
Thanks for the valuable suggestions. Looking to the risk involved and the time period required to carry out the repair we have decided to put in a globe valve to control flow temperorily (as process allows for it) and to procure new valve body.
Thanks again,
Vinod
