test pressures and stresses for pressure vessels according to new regulation 87/11

Abstract

With the enforcement of Regulation on Technical Requirements for Design, Development and Conformity Assessment of Pressure Equipment and Regulations on the Inspections of Pressure Equipment During the Lifetime (Službeni glasnik RS, No. 87/2011), the Regulation on Technical Normatives of Stable Pressure Vessels has ceased to be valid (Službeni glasnik RS, no. 16/83). New Regulations have brought novelties regarding the essential requirements – allowable stresses and test pressures. In this paper, test pressure values and stresses resulting from these pressures are calculated. Differences in pressures and stresses generated by applying the “new” and “old” Regulations which are applied to pressure vessels designed under old Regulations, are analysed and discussed.
