Graphilor® graphite bursting discs

When the operating temperature exceeds 165°C, a thermal insulation system must be provided.

The thermal insulation device maintains the temperature of the safety disk at a temperature compatible with its operation.

The rupture detector is the ideal tool to locate in real time the rupture of your discs.

It is available on all of our series of bursting discs, from 25 to 600mm diameter. It is installed on the disc between the 2 flanges.

Ideal for medium and high pressures
