“…The leading cause of stress concentration is the abrupt transition of structural rigidity between the support and the pressure vessel. Ren Haidong et al [4] found that the saddle structure itself is stressed because all forces acting on the vessel are ultimately transferred to the support. The saddle support having other related stresses and the internal stress of the pressure vessel, Therefore the design of the saddle support is critical while designing the horizontal type pressure vessel.…”

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.
