Support Analysis of Horizontal Pressure Vessel Using FEA

Abstract:

Saddles are used to support the horizontal pressure vessels such as boiler drums or tanks. Since saddle is an integral part of the vessel, it should be designed in such a way that it can withstand the pressure vessel load while carrying liquid along with the operating weight. This paper presents the stress analysis of saddle support of a horizontal pressure vessel. A model of horizontal pressure vessel and saddle is created in Ansys software. For the given boundry and loading conditions, stresses induced in the saddle support are analyzed using Ansys software. After analysis it is found that maximum localized stress arises at the saddle to vessel interface near the saddle horn area. The results obtained shows that the saddle support design is safe for the given loading conditions and provides the theoretical basis for furthur optimisation.
