Design of liquid oxygen storage tank with welded joints & its Safety
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2015, Vol 5, Issue 4
Abstract
In this paper we design a high pressure liquid oxygen storage tank. Liquid oxygen storage tank is leak proof container design to hold and store liquid oxygen at cryogenic temperature at a pressure substantially different from the ambient pressure. Design is carried out according to American Society of Mechanical Engineers (ASME) code, deals with the study of various metals. Various methods of fabrication like welding and testing are also included. Using CATIA software 3D model has been prepared. The final Liquid oxygen storage tank has to be designed in a tradeoff between strength and thermal aspects. To overcome the problems in existing storage tank design, in our proposed design the stresses developed and corrosion in the circular cross section with hemispherical end caps welded are very less when compared to flat cap on the storage tank top. Also in the circular cross section, the stresses and deflections are minimum, and from the results Factor of safety in the case with hemispherical end caps is 1.8
