Rapidly Design Safety Relief Valve Inlet Piping Systems

摘要

Safety relief valves (SRVs) used to protect against overpressure require well-designed inlet piping for proper operation. The engineer's job is to produce these designs from a thorough understanding of the inlet piping as a key component in the safety relief system and the correct application of the governing fluid dynamics principles. This article will present a technique for analysis and design using classical ideal-gas adiabatic fluid flow principles. Also, it will discuss the advantages of using the personal computer (PC) to quickly arrive at accurate designs. This work applies to SRVs in which relief flows are limited by sonic conditions at their nozzles.
