I have a vessel with the following specifications, which has a bolted head,
which gasket is suitable for this vessel?
The upper head should be opened once a year.
design pressure: 178 bar
Design temperature: 140 C
inner diameter: 900
tanks
is it necessary to use the saddle wear material the same as shell material? (pressure vessels designed by asme)
for example in my heat exchnger the shell material is a106-b and i want to use st52-3 for wear plate materials.
thanks
