Sheet Spiral Heat Exchanger Minimum Thickness

[kmgw4c]

Hello all,

I'm currently working on finding the ASME minimum thickness for the "Shell spiral" of a sheet spiral heat exchanger. Any tips on where to find guidance in BPVC? UG-19(b)says non-spherical/non-cylindrical shapes with no guidance should use U-2, but I'm struggling to find anything. TIA!

Don't know anything really about spiral HX's but I'd kind of think UG-16(b) would apply.

Regards,

Mike

The problem with sloppy work is that the supply FAR EXCEEDS the demand
