| Abstract: | The forecast model for the static strength and load of the steel internal pressure vessel is set up in this article. By using the reliability design method, the distribution parameter is analyzed from the aspects of design, manufacturing, checking before acceptance, safety supervision and operation. The initial reliability of the vessel static strength is linked quantitatively with the confidence coefficient of the calculation formula and the safety coefficient. The analysis result provides a basis for drawing the specifications of pressure vessels. |
