Taking the special-shaped flange for a type of heat exchanger as the researching object, applying the finite element software ANSYS, author has analyzed the temperature field of special-shaped flange under stable condition, and also calculated the stress distribution of this special-shaped flange under the action of both temperature and pressure loads.According to ASME code,strength evaluation was made for the dangerously forced portion of the special-shaped flange, result indicates that strength of the special-shaped flange of the heat exchanger can satisfy the safety requirement.
