Comparison of pipe internal pressure calculation methods based on design pressure and yield strength

Abstract

Von-Mises pressure yielding limit calculationmethod for thick wall pipe with safety factor could be usedas a design pressure calculation method and would be universalfor any wall thickness and diameter ratio pipes.The study showed us, that ASME, DNV, ISO andСНиП standards are designed for thin wall pipes and canbe over thick wall pipes Von-Mises criteria. It happensbecause in methodology for thin wall pipes is no radialstress.The purposed method can be used for thin andthick wall pipes.The safety factor for design pressure in the purposedmethod is used from appropriate standard.
