Rupture Disc and Safety Valve In-situ testing of safety valves
Normally, safety valves have to be removed in order to test whether they are functioning correctly. This is time-consuming and expensive. However, you can test your safety valves without moving them anywhere when you use Rupture Discs. The space between the rupture disc and the valve stroke is pressurized.
KUB has a back pressure resistance of 135 %. THis means the rupture disc remains undamaged while the safety valve is being inspected. If in-house regulations nonetheless require the safety valve to be removed for inspection, the rupture disc can be left in position in a separate flange connection in order to close the opening while this work is being performed.
