Mechanical Integrity for Ammonia Refrigerating System Piping and Pressure Vessels
Author: Ronald A. Cole, P.E. and Godan Nambudiripad, P.E.
Mechanical integrity is an issue that is not universally understood within the ammonia refrigeration industry The guidance currently available to our industry on this issue seems to be based on the experience of the chemical and petrochemical industries. There is little doubt that our industry can improve on this situation, especially for piping and vessels. The paper includes a case study in which the authors dealt with all of the practical issues associated with creating and developing a mechanical integrity program from the ground up. The authors then refine the method using a rational approach, and share major parts of it. The paper shows a cost-effective mechanical integrity program tailored specifically to ammonia refrigeration systems, focusing on critical and high-risk areas.
