Abstract：Openings and nozzles in a pressure vessel may affect the load-carrying capability of the vessel. Finite element method was used to analyze the critical load of a horizontal vessel with a nozzle under external pressure loading and the limit load under internal pressure loading, with the effects of openings and nozzles with different sizes and thicknesses on the load-carrying capability of the horizontal tank being specially investigated. The results show that the critical load showing the vessel instability almost keeps constant when a nozzle is present at an opening, but that the limit load reflecting the vessel strength obviously decreases. For the same nozzle thickness, with increasing nozzle diameter, the limit load of the vessel remarkably decreases, with the critical load under the external pressure keeping constant. For the same nozzle diameter, the limit load of the vessel significantly increases with increasing nozzle thickness, with the external pressure increase being very limited.
