For industrial fire extinguishing, according to the ambient conditions and application conditions, systems; wet pipe, dry pipe dominant type and preaction type can be selected.

When choosing aqueous extinguishing systems, the most suitable fire extinguishing system should be selected for the area where it will be used.

Water fire extinguishing systems must be maintained after their installation.

The purpose of maintenance is to maximize the effectiveness of the systems.

All water fire extinguishing system designs are based on NFPA13 and TS EN 12845 standards, and NFPA25 (NFPA Test And Maintenance, Inspection) standards are observed for the maintenance phase.

In addition, if it is suitable for the design of extinguishing systems, it is sufficient to have TS EN 12845 certificate and TS EN 671 standard certificate for fire cabinets. For this reason, the design, installation, tests, maintenance and repairs of the system should be carried out by a company such as REFORM YANGIN, which has a team of experts and experts in fire.

The sequence of steps to be followed in the design of sprinkler water extinguishing systems is as follows;

• Determination of hazard classes,
• Selecting the system type,
• Determination of water needs,
• Determination of sprinkler extinguishing types,
• Determination of piping principles,
• Hydraulic analysis and determination of pipe axing details are included in the figure.

The most common type of water extinguishing systems today are the systems called sprinkler systems. NFPA13 and EN12845 are the standards used in water extinguishing systems.

Sprinkler system mainly consists of fire pump, pipes, pipe hangers and fittings, system control valves, monitoring switches and sprinkler heads.

Sprinkler systems are used as automatic fire extinguishing systems in residential buildings, business centers, industrial facilities, storage areas, parking lots, etc. Sprinkler systems can be classified in four different ways according to their working principles. Selecting and applying the right system type according to the application area, risk group and environmental factors is of great importance in terms of system operability.

• Wet Pipe Sprinkler System
• Dry Pipe Sprinkler System
• Deluge Sprinkler System
• Preaction Sprinkler System
• Preaction Sprinkler System without Interlocking
• Single Locking Preaction Sprinkler System
• Double Locking Preaction Sprinkler System

In a wet pipe sprinkler system, there is continuous water in the pipe. It can be applied if the ambient temperature does not exceed 95°C. In places with low temperatures where there is a risk of freezing of the water in the pipe, measures should be taken to prevent freezing of the water.

With the fire pump capacity determined as a result of calculations, water is kept pressurized in the pipes. In case of fire, the sprinkler head is automatically activated by the high heat generated and the water in the pipe is discharged into the environment with the effect of pressure. In this way, the fire is taken under control and extinguished.

The sprinkler head differs according to the activation temperature and can be distinguished by the different color inside. Thanks to the wet alarm and/or flow switch used in this system, information is transmitted to building management systems and fire detection systems.

In dry pipe systems, instead of water, the pipe network is filled with compressed air or nitrogen gas at a level that keeps the valve between the water source and the pipe network closed. The air pressure is automatically controlled by a device placed at the network inlet.

When the heat released from the fire activates any sprinkler, the pressure in the pipe network will drop rapidly. This pressure drop will cause the valve at the inlet of the dry pipe network to open, thus filling the pipes with water and discharging water from the open sprinklers to the fire scene.

Dry pipe sprinkler systems can be used in low temperature areas where wet pipe systems cannot be used. However, the valve section at the inlet of the dry pipe system should be placed in heated spaces.

Preaction sprinkler systems are similar to dry pipe sprinkler systems. However, it is preferred in places such as archives, museums, libraries, historical buildings where the damage caused by water discharge is high. The discharge of water into the environment occurs only when the sprinkler head is activated and/or a signal is received from the automatic fire detection system.

Information is transmitted to building management systems and fire detection systems through the pre-action alarm valve and/or flow switch in the system.

Water passage from the pre-action alarm valve to the pipe system starts with the activation of the sprinkler heads or the activation of the automatic fire detection system.

The activation of the detectors in the detection system or the pressure drop in the pipe causes the pre-action alarm valve to open.

Foam extinguishing systems are preferred for extinguishing intense flammable flammable chemicals or fuel fires that cannot be extinguished with water. The fire extinguishing foam used as extinguishing agent covers the burning surface and cuts air contact with the fire.

The three main components used in foam extinguishing systems are foam solution, water and air. Foam solution expands under pressure with the help of water and air and is discharged into the environment through nozzles. The foam used in foam extinguishing systems also creates a cooling effect.

Gas extinguishing systems are the most accurate fire extinguishing systems that should be preferred for places where water, foam and powder extinguishing systems are not effective and are also called clean extinguishing systems. Gas extinguishing systems provide maximum protection without causing any damage to the materials in the environment where they are used.

Compared to other fire extinguishing systems, it does not leave behind a large debris after the fire extinguishing process.

In-Panel Gas Extinguishing Systems are applied with 2 different methods, Direct and Indirect, using FM200™, NOVEC™1230 with a working pressure of 16 bar and CO2 gas with a working pressure of 50 bar.

This system consists of a cylinder in which the extinguishing gas (FM200™, NOVEC™1230 or CO2 gas) is stored, a gas discharge valve and a plastic-based pipe with special orifices on it. When the temperature inside the panel reaches 120 °C, the fire is detected and the gas is discharged by rupturing the orifices on the pipe.

FM200™ (HFC-227ea), NOVEC™1230 (Fk-5-1-12) or CO2 gas are commonly used as extinguishers in these systems.

When these systems are to be supplied with approval, they can be supplied with LPCB approval up to 2 m³ volume.

This system consists of a cylinder where the extinguishing gas is stored, a gas discharge valve, a plastic-based pipe with special orifices on it and a seamless stainless steel pipeline that allows the gas to discharge. When the temperature inside the panel reaches 120 °C, the orifices on the pipe rupture, the fire is detected and the valve on the cylinder is triggered by the pressure drop in the hose and the gas is discharged from the special orifice nozzle at the outlet of the fixed stainless steel piping.

FM200™ (HFC-227ea), NOVEC™1230 (Fk-5-1-12) or CO2 gas are commonly used as extinguishers in these systems.

These systems are available from foreign manufacturers as single cylinder up to 10 m³ volume.

Fire pumps are of great importance against fires that may occur at any time. Fire pumps, which work more efficiently than normal pumps, quickly meet the water supply. It is used in buildings, industrial areas, wherever there are people and fire can occur.

Fire pumps are indispensable equipment for extinguishing fires today. Fire pumps that work and should work instantly in emergencies must be checked and maintained according to the annual control process.

Periodic inspections of fire pumps, which play an active role in fire fighting, are subject to the “Regulation on Health and Safety Conditions in the Use of Work Equipment” and “Regulation on the Protection of Buildings from Fire”.

Unless otherwise specified in the relevant standards specified in this regulation, periodic checks of the installations are carried out once a year. Fire Installation periodic controls are carried out in accordance with the criteria specified in TS 9811, TS EN 671-3, TS EN 12416-1 + A2, TS EN 12416-2 + A1, TS EN 12845 and NFPA standards.

REFORM Fire helps you to prevent a possible dangerous event and to meet your legal requirements by presenting the deficiencies, non-conformities or dangerous situations detected as a result of the fire installation controls carried out with its expert team and equipment.

Sealing test, FM 200 (HFC 227 ea), Novec 1230 (FK-5-1-12), Inert gas (IG 01, IG 55, IG 100, IG 541) gas extinguishing systems with total volume protection. 

Room Tightness Test measures the amount of oxygen in the air that causes fire and measures are taken according to the measurements. By mixing homogeneously into the air, it extinguishes the fire by reducing the oxygen rate in the environment below combustion.

The environment must be fully sealed. Otherwise, the gas transmitted to the environment will escape with the air. In this case, the oxygen level of the air in the environment rises again and situations such as re-ignition and non-extinguishing of the fire may be encountered. The volumes where the gas extinguishing system will be applied are tested for tightness according to NFPA 2001 Annex C. It is only necessary to test with door fan test application. With this test, the maximum and minimum possible openings in the volume are determined.
