Fireproofing of PSVs
Posted: 21 Jul 2026, 06:27
In what cases PSVs designed for fire cases can be fireproofed? Our process engineers have recommended us to apply fireproofing on some PSVs. What can be the driving factors?
Some facilities require equipment to remain functional for 30 minutes, 60 minutes, 120 minutes, depending on evacuation philosophy.
If a PSV is needed to continue relieving pressure during prolonged fire exposure, fireproofing may help preserve its mechanical integrity.
