Using DIERS two-phase equations to estimate tube rupture flowrates

摘要

ASME Section VIII and API 521 discuss the need to design and protect heat exchangers against overpressure due to a tube rupture. API 521 specifically addresses requirements and approaches to solve this problem. The first solution is to raise design pressure of the low-pressure side to a minimum of two-thirds of the design pressure of the high-pressure side. However, this may not be desirable due to economics or other design reasons.
