ABSTRACT
According to stress assessment methods in the standard of steel pressure vessel- design by stress analysis (JB 4732 - 1995), two paths were constructed, including a traditional pathl and a path2 recommended by pressure vessel GB 150 - 2011, and the minimum thickness of the nozzles for openings with a diameter of 100~1 000 mm on cylinders with a diameter of 1 000~3 000 mm was designed by using finite element method (FEM). The analysis result was compared with that from area replacement method. The result shows that the area replacement method is danger than the traditional path1, but a little more conservative than the path2 appealed by GB 150 - 2011. According to the practice experiences and the finite element results, the path2 is more suitable to practical situation.
