Pickling Line

If a fire starts in pickling line, it spreads very quickly because the pickling process generates hydrogen. Also there is a risk of explosion from chemical processes. The plastic of reservoirs (pickling tanks), supply lines and exhaust air system are flammable.

The fire protection system is a combination of water mist extinguishing system and CO2 local application system to protect the oiler units on the pickling lines. A Co2 gas based extinguishing system components can reduce the fire risk in exhaust system and building up of combustible hydrogen by reducing the concentration of oxygen to less than 6 per cent. The materials of all the components of fire extinguishing system are designed for pickling line environmental conditions.
