Customized design bursting disk/ rupture discs used for oil/ gas well separators
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.
Advavtage
1.Simple structure, high sensitmty, accuracy, zero leak, strong discharging capability, and strong capability of recycling under pressure
2.It maintains high operation precision even in sticky, high-temperature,low-temperature, and corrosive environments in combination with a safety valve.
3.It is an ideal safety device for ultra-high pressure vessels, widely used in the omchemical, pharmaceutical, new energy, and low-temperature equipment industries.
4.It can be classified into three catagories: domed bursting discs, reverse domed bursting discs and flat bursting discs.
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.
