The burst strength of rotary compressor pressure vessel directly affects the safety. Therefore, it is mandatory to ensure the strength of the pressure vessel. Major factors that determine the burst pressure of pressure vessel are stress concentration around the suction and discharge hole as well as its shape and thickness. In this study, stress concentration of the pressure vessel is investigat...

This paper systematically discusses the significance of pressure vessel inspection, defines main body annual inspection vessel, and puts forward matters needing attention in process according to existing situation, so as provide a certain reference for smooth development vessels.

This paper presents the design analysis of saddle support of a horizontal pressure vessel. Since saddle have the vital role to support the pressure vessel and to maintain its stability, it should be designed in such a way that it can afford the vessel load and internal pressure of the vessel due to liquid contained in the vessel. A model of horizontal pressure vessel and saddle support is creat...

in this paper, multi-stage optimum design of composite pressure vessels is presented. the design variables for composite vessels include the head shape, the winding angle, the layer thickness, the number of layers, and the stacking sequence. a parameter called modified shape factor is introduced as an objective function. this parameter takes into account the effects of the internal pressure and...

The main objective of this paper is to propose various types of Finite Element Methods used for the calculation of burst strength of pressure vessel. The pressure at which the pressure vessel should burst if all of the specified design tolerances are at their minimum values is called burst pressure. Prediction of burst strength is the very important aspect in the pressure vessel design. The pre...

In this paper the effect of composite hoop-wrapped on stress intensity factor for semi-elliptical external crack which located in spherical pressure vessel, were investigated through the Finite Element Analysis. In order to find the effect of some parameters such as composite thickness and width, internal pressure and crack geometry, comparisons between different cases were done and discussed i...
