压力容器设计时，应该考虑接管应力对容器壁厚的影响，在计算接管应力时，应力值的选取至关重要，一些规格书中所列的应力值与标准上计算出的应力值是不相符的e并且计算书要选取正确的计算方法，WRC107计算方法在有些特定开孔处是无效的，它不能反应出接管壁厚变些对圆筒够卑力变化的影响，因此是不可靠的。计算式应选取正确的计算方法，保证设计容器的可靠性。

In the pressure vessel design, should be considered the hook up stress effect on the vessel wall thickness. When calculating the hook up stress, the selection of stress value is very important. Some stress values listed in the specifications with stress values through the standard to calculate is not consistent. And the calculation should select the correct method, WRC107 calculation method in some specific trepaning is invalid. It cannot reflect the thickness change for the affect on the cylinder body stress changes, so it is not reliable. Calculation formula should be the correct calculation method to ensure the reliability of the design of container.
