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

Abstract

Von-Mises pressure yielding limit calculation method for thick wall pipe with safety factor could be used as a design pressure calculation method and would be universal for any wall thickness and diameter ratio pipes. The study showed us, that ASME, DNV, ISO and CH standards are designed for thin wall pipes and can be over thick wall pipes Von-Mises criteria. It happens because in methodology for thin wall pipes is no radial stress. The purposed method can be used for thin and thick wall pipes. The safety factor for design pressure in the purposed method is used from appropriate standard.
