What is Explosion Isolation?

Explosion insolation is the most common form of fire protection used in industrial processes. When an eruption occurs, it can quickly spread to related process parts, for example, through a pipeline. The result is several secondary explosions that occurred in other parts of the plant, posing an immediate threat to the lives of employees and the destruction of assets and property.

However, with eruption isolation, this risk is reduced. There are various forms of explosion insulation. There are passive techniques such as valves or barriers, or there are active systems such as high-speed valves or chemical isolation.

The explosion isolation system acts as a barrier, preventing the eruption from entering adjacent facilities. Ignition protection insulation must be designed by a specialist for the specific application, taking various factors into account. You can also surf the web to learn in detail about an ignition isolation valve.

A valve is installed in the pipe and if ignition occurs, the metal flap inside closes at the initial pressure wave of the explosion and forms a barrier. It blocks the propagation of the explosion source and eliminates the possibility of a secondary eruption.

After an explosion, a quick check of the valve and removal is usually enough to get the system back into operation and protect it again. When using the B-FLAP isolation valve, the user can clearly see the position of the valve on the outside of the flap, as indicated by the small part of the valve body.

However, there is an optional position indicator accessory that can be connected to the control panel to alert the user when the valve is closed.
