Design length_UG-29 & UG-80

[K.P.M.]

Hello everyone,

As per UG-29 & UG-80 , To find chord length & e which length L0 should consider?

For my pressure vessel 1000mm is pressurized shell length. if I take standard plate (1250 or 1500 mm width) for shell fabrication then which length L0 (design length) to consider for fig. UG-29.2 & UG-80.1. .......?

KEJUL, assuming from your sketch "Tank Line" is the head tangent, L = 1000 + 1/3 head depth. The flat head is a line of support, the open end is not. See UG-28(b).

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

Thanks Mike...
But for shell calculation which length should consider for same.......

KEJUL, surely you don't consider an open end outside the pressure boundary a line of support?

Mike,

I consider 1000 mm to calculate shell length... Is it right?

Looks like 1000 + 1/3 head depth to me...
