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
