Subject: [MW:6205] PWHT of Bigger diameter & Long vessels
Dear all,
we have several equipments of diameter 5mts & above & length 30 mtrs & above. Our specs calls for PWHT in an enclosed furnace.
some of our fabricators expressed inability due to furnace size restrictions& informed us that use of Temporary Modular furnaces will pose risk to Quality of final product.
I need your advice on the following
1. Is doing PWHT in modular furnaces will create any problems to the equipment (in terms of quality)
2. can the temperature be properly controlled
3. Pwht can be performed properly without overheating or Under heating.
thanks
Suresh
