A rupture disc is a non-reclosing pressure relief device that protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
Explosion venting provides a planned pathway for expanding gases to escape. It is one of the most common and effective methods of explosion protection. Explosion venting provides overpressure protection from potential industrial explosion hazards.
Tank venting protects tanks against excessive pressure or vacuum by controlling evaporation losses and allowing vapors to flow freely. Venting equipment includes Emergency Vents, Gauge Hatches and Pressure and Vacuum Relief Valves, (PVRV).
