Three-way pipes, T and Y pipes, are very important connecting components in pipeline systems, their strength are related to the
safety of pipelines. In the case that crack is not detected in the three-way pipe, ANSYS finite element program version 5.6 is applied to study
the stress distribution of the three-way pipe and to obtain the optimum fillet radius in the crotch region of the two pipes. The reasonable
intersection angle φ of the two pipes is also obtained. In the case that a surface crack is detected in the three-way pipe, the maximum stress
intensity factor (SIF) near the front of the surface crack is studied.
