When should a ruptured disc be replaced?

Maintenance Frequency. While rupture disc manufacturers would like to recommend replacement of every rupture disc every year, that is not a realistic expectation. As shut- downs for maintenance activities are stretched further and further apart, it is not unusual to expect 3 to 5 years of service from the rupture disc.

What are rupture discs used for?

A rupture disc is a non-closing pressure relief device used to protect industrial applications from overpressure- or vacuum-related events.

Where are ruptured discs located?

When used in series with a pressure Relief valve, the rupture disk is usually installed upstream of the valve. The disk will protect the valve from process media that can corrode or plug it. The disk can also act as a seal, preventing any leakage through the valve unless the disk is ruptured.

How do you specify a ruptured disc?

What must be observed when selecting a rupture disc?

1. The system to be protected and process particularities.
2. Burst pressure.
3. Burst temperature.
4. Permissible overpressure or vakuum.
5. Process medium.
6. Working pressure (operating pressure)
7. Vacuum resistance.
8. Pulsation.

What is a bursting disc in an air compressor?

A bursting disc is a copper disc provided at the air cooler of the compressor. It is a safety disc which bursts when the pressure exceeds over the pre-determined value due to leaky air tubes of the cooler (intercooler or aftercooler).

How painful is a ruptured disc?

How do you stop an air line from exploding?

How to prevent starting the air line explosion ?
