    Axial Compressive Stress in Horizontal Vessel

    Thank you for taking the time to reply. - General dimensions are 70" OD, 432" seam to seam length, 0.12" thick, MDMT -320 F w/ max temp of 100 F, 38psig MAWP. - This is a vacuum insulated transport vessel, hence the 2x loading situation to design for. - Supports must be at end. I don't want to...

My concern is with the longitudinal axial compressive stress when loaded. It’s my understanding that I am supposed to use UG-28 and solve for the “B”...
