When the high-pressure side of a heat exchanger is significantly higher than the pressure at which the low-pressure side was designed, damage to the low-pressure side of the exchanger or to its attached piping can occur if an instantaneous tube rupture were to occur. API STD 521 provides two options for mitigating the risk associated with an internal tube failure. This article primarily covers the second option to perform a heat exchanger design analysis, which E2G has named a Tube Rupture Credibility Assessment (TRCA).  (EEPub090)
