Abstract

Upon the adoption of regulations for pressure equipment the series of standards SRPS EN 13445 began to apply. The paper illustrates strength calculation of a vertical cylindrical pressure vessel of austenitic steels according to SRPS EN 13445-3. The calculation includes a cylindrical shell and two shallow torispherical dish ends exposed to internal pressure of 0.5 MPa. The influence of working conditions and different values of the joint coefficient on the thickness of the cylindrical shell and dish ends is analysed.

Keywords: pressure vessel, strength calculation, austenitic steel, SRPS EN 13445
