Study and simulation analysis of design technology for large-scale horizontal LPG mounded pressure storage tank

According to the current status of no design technology for large-scale horizontal LPG mounded pressure storage tank at home, the design and simulation analysis of the first type in China is carried out according to ASME VIII Div1&2 and EEMUA190 standards. The results show that when the tank body is inflated, there is a great stress on the joint between the head and the tank wall, and will be obvious on the surface when the tank body is settled in the middle; from the comparison of seismic conditions and normal operating conditions, the earthquake has a greater impact on tank settlement while a little stress on the tank body; under normal operating conditions and water pressure test, the tank material don't reach the material yield point, and there are some margins, so the tank body design is reasonable and can be adapted to work under various working conditions.
