Description

An elastic-plastic nonlinear analysis is conducted by ABAQUS software to study the sealing structure of flange connection with different material in horizontal channel. The processes for pre-tightening of primary bolts and pressurizing in the horizontal channel are simulated by finite element multi-step skill. The stress distribution and sealing performance of primary flange is studied. The analysis results show that the double O-ring sealing structure in horizontal channel can meet the requirements on strength and sealing during the pre-tightening and pressurizing processes.
