An unfired pressure vessel (UPV) is a closed container holding fluids (liquids/gases) under pressure generated externally, not by direct flame or combustion, like air receivers, storage tanks, heat exchangers, or sterilizers.

These vessels store energy and require strict design, fabrication, and regular inspection (e.g., by JKKP/DOSH in Malaysia, following standards like ASME) to prevent catastrophic failures from corrosion or damage, ensuring worker safety and legal compliance
