The invention provides a method for calculating design pressure of a pipe fitting and a method for determining the wall thickness of the pipe fitting by calculating the design pressure value of the pipe fitting. the pipe fitting strength needs to be the same as the pipeline strength; the design pressure of the pipe fitting is determined according to the specification and material of the pipeline;according to the pipe fitting code in the pipe fitting ordering list; an external pipeline material connected with the pipe fitting and a pipe meter number are determined; according to the 2.1 < th >ASME B < 16.9 > strip, determining the weld coefficient of the external pipeline; and the design pressure of the pipe fitting is obtained through calculation according to the formula (shown in the specification), and then the thickness of the pipe fitting is further calculated. According to the calculation method, the construction cost is reduced, and the safety of a pipeline system is ensured. 本发明提供种管件设计压力的计算方法以及通过计算管件的设计
