Fire protection installation - pipes and valves

Added: Friday, 7/21/2023


Safety is undoubtedly the most important thing. There is a high risk of fire in many places. For this reason, it is necessary to ensure proper fire protection installation. Not only its type is important, but also its components. Today we will tell you which pipes and valves to choose.

Types of fire protection installations

Automatic shut-off valve for Danfoss EV220B DN65 fire protection system 2 The fire protection installation is intended to prevent the spread of fire. At the same time, it is also intended to minimize potential losses and enable efficient evacuation. There are several types of fire protection installations. The most standard one is the one that uses water as an extinguishing agent. The system consists of a fire water tank, a pump and a network of pipelines with sprinklers. Of course, you must ensure that constant water pressure is maintained in the installation. The operation is very simple - the sprinklers contain ampoules filled with water that burst under the influence of high temperature. This solution is certainly effective because sprinklers operate on the principle of selective extinguishing, which means that they extinguish only the place where the threat occurs.

An alternative is a fire-fighting installation using water mist as an extinguishing agent. In this case, the water takes the form of mist, which cuts off the flow of oxygen to the air source. Importantly, the medium is dispersed in droplet form, which allows for extinguishing an even larger area. There is also a fire-fighting system using foam. This is a good solution in places where there is a risk of fire of solid, liquid or gaseous substances. Foam extinguishes even fuel well. You can also opt for a gas fire protection system. This solution is used in places where flammable liquids are stored, but also in electrical switchboards, server rooms and libraries. One of the most frequently used gases is carbon dioxide or argon.

Which pipes are suitable for fire protection installations?

Fire protection installations should have cables in the form of double-layer galvanized steel pipes. They should comply with the PN-74/H74200 or PN-81/B10700.02 standard. You cannot forget about using threaded connections. Galvanized fittings and connectors are best for this purpose. Medium galvanized pipes can also be used. However, one important thing should be remembered, namely that the slope cannot be omitted when laying, because only then is it possible to effectively vent or drain the main pipes.

Valves in the fire protection system

Valves in the fire protection system must ensure the proper pressure of the extinguishing agent. Therefore, valve operation can be controlled in various ways. The Fire Protection Act should be followed. It clearly reads that there is an obligation to use valves that cut off the utility water supply, because only then can the optimal water pressure in the fire protection system be achieved. Traditional valves can be used to maintain the proper parameters of the extinguishing agent.

In such a case, it is best to install them on the riser of the internal fire protection system. This type of valves do not require electricity to operate. An alternative to this type of valves are normally open valves. They are used in places where there is access to emergency power. Normally closed valves are used in so-called dry risers. When choosing this type of models, pay attention to the installation - the coil should be directed upwards. The material from which the valve is made should meet the most stringent quality standards.

For the fire protection system to function efficiently. Appropriate watering valves for fire risers should be selected.

Such elements of the fire protection system are available at the Onninen wholesaler. A good choice may be the automatic shut-off valve for the Danfoss EV220B DN65 2 1/2" fire protection system . It is worth knowing that it will work in the case of a medium temperature ranging from minus 25 degrees to 90 degrees Celsius. It is a voltage-free closed type. The maximum working pressure is 10 bar.

The Grundfos RST50 IC safety valve is also worth mentioning. It is a priority valve, so it is a combination of a regulator and a pressure limiter. You should also know that in this model there is an automatic possibility of cutting off the domestic and utility installations.

You can also choose an automatic shut-off valve for the Danfoss EV220B DN100 4" fire protection system , with a working pressure of 15 bar. You should also know that it is made of cast iron. There is one connection via a flange.
