在API 521中,提出压力在1700KPa以上的设备需要设置BDV:” A common application is compressor depressurization, in case of a fire, leakage, or seal failure. Another is emergency depressuring for the fire scenario, which is often considered for large process equipment operating at a gauge pressure of 1700 kPa (~250 psi) or higher. ”
但是没有解释1700KPa的来源和依据是什么,为什么不是更高或更低?对于泄放终压,API 520提出为690kPa,这个数据来源和依据是什么,为什么不是更高或更低?
希望有了解的同行能够解释下!
