REASONS FOR EXCESS PRESSURE IN A VESSEL
There are a number of reasons why the pressure in a vessel or system can exceed a predetermined limit. The most common are:
· Blocked discharge
· Exposure to external fire, often referred to as “Fire Case”
· Thermal expansion
· Chemical reaction
· Heat exchanger tube rupture
· Cooling system failure
