Pressure reflief valve replacement concave bursting discs / rupture disk for safety
The rupture disk safety device is a non-reclosing pressure relief device consisting of such parts as a bursting disc (component) and a holder (supporting ring). It is able to burst at a certain temperature or pressure, protecting equipments and staff safety by releasing the pressure in the system.The bursting disc is an important safety device for pressure vessels and pipes.
It is determined by the tensile strength of the material employed. System pressure is subjected to the concave side of rupture disk on normal operating condition. When excessive pressure occurs on the protected system, the dome begins to thin out and the disk bursts, providing a full relief opening.
· Simple Rupture Disk (LP):withstand backpressure, non-backpressure or vacuum conditions with disk holders.
· Features
· Broad range of application, and can choose the corresponding assembly according to different burst pressure and vent area.
· Manufacturing ranges depend much on material strength.
· Designed for gas, liquid service
· Suitable for high temperature and pressure conditions.
· Maximum operating pressure equal to or less than 70% of the minimum burst pressure, and not suitable for pressure pulsating conditions.
· Fragments on burst.
· Short service life and easily cause creep deformation and fatigue damage
· Obvious temperature effect may cause burst pressure fluctuation. The temperature goes up while burst pressure declines.
