Hello. One more thing. I asked the question about stress relieving the
finished hull also. There are some companies that have huge ovens to do just
that. One in Texas that makes the tank heads I want does it on tank heads for
high pressure, and will even do a whole tank.
Their oven is very large. I think stress relieving is required on
tanks that store very cold things and create problems with cold brittle
stress.
The company is " Fort Worth F & D Tank Head " --great prices
there.
