A Review on Skirt to Dished end Joint of Pressure Vessel

In pressure vessel at the junction of skirt to head (Dished end) are subjected to a combination of thermal stress and structural stress. Due to excessive temperature gradient at junction in hot operating cases can cause unpredicted high thermal stresses and high pressure cause high structural stresses which makes design of vessel critical. Then fracture of the vessel may occur as a result of cyclic operation. So motive of this paper is to reviewing different research paper on skirt to head joint and finding different causes and parameter of crack generation.
