| Abstract: | Welded piping tees with common dimensions without defect under in plane moment were analyzed by an elastic plastic finite element stress analysis method by means of the FEA software ANSYS,and the related FEA solution database were established. Based on the database,the formula for the plastic limit in plane moment was fitted with higher accuracy. The basic data and approach are provided to be used for the strength analysis of the piping tee. |

| Keywords: | piping tee plastic limit in plane moment finite element database estimating formula |
