The oil industry plays a significant role in our everyday lives, powering our vehicles and providing asphalt for the roads we drive on as well as the raw material for almost all types of plastics. Currently, the global current demand for oil averages 98.51 million barrels per day (mbd), which represents approximately $6.8 billion (in US dollars) in daily economic activity worldwide.

Considering that a large petroleum refinery can process as much as 800,000 to 900,000 barrels per day, the cost of a single refinery fire can be devastating, potentially reaching more than $60 million in economic losses for every day production is interrupted.

In high-hazard settings such as oil extraction facilities, refineries, and buildings in industrial parks where chemicals and other flammable liquids are stored, deluge systems are the preferred type of fire sprinkler system. Often referred to as open sprinklers, deluge systems are designed with open nozzles and empty, non-pressurized lines and are designed to discharge through all the sprinkler heads in the system. Because they deliver a large quantity of water all at once, they offer the best protection in the event of a fire in these types of facilities. 

Most industrial fire protection valves are highly robust by design. However, they can still crack under the pressure of water freezing inside them, making their winterization critical to protecting the ability of the system to function properly in the event of a fire.

Water surge or water hammer is a pressure wave in a piping system caused when a fluid in motion is forced to stop or change velocity or direction suddenly. Pressure surges in fire water systems can be caused by a number of different factors, such as a valve closing or opening too quickly or a pump starting or shutting down suddenly. This momentum change can create a significant and potentially damaging pressure rise.

Most fire protection systems are designed to operate at a maximum working pressure of 12 barg (175 psi).  Pressure waves from water hammer or pressure surge can easily exceed 50 barg (740 psi), thus creating a very real threat of damage to piping and instrumentation.

The pictures below show two examples of catastrophic damage to piping and accessories caused by water surge/water hammer in fire protection systems.

When firefighters get called in, the last thing they want to deal with is a clogged nozzle. The consequences may be tragic if a fire does occur and the fire sprinklers don’t turn on. These malfunctions are key indicators of a vulnerable fire protection system. And unfortunately, you may not become aware of the problem until it’s too late.

In municipal fire pump applications, a water booster pump is often used to take water from a public service main or private use water system. The booster pump serves the purpose of increasing the existing water pressure to one suitable for the fire protection system. When designing or installing such a water booster pump, it is important to consider certain critical issues specific to water booster pumps.

From an engineering point of view, almost all valves leak by some measure. Valves may be said to be "bubble tight" or "zero leakage,” but in actuality most standards will let small amounts of water through. Every fire protection valve is subject to regulation by government, corporate, and/or other agencies. Valves must comply with safety standards as defined by established safety organizations such as the National Fire Protection Association (NFPA) or UL (Underwriters Laboratories).

Fire presents a significant and ever-present danger in power plants of all types. Regardless of whether you are dealing with a fossil fuel, nuclear, or hydro plant, it is essential to have the right kind of fire protection in place. Depending on the area of the plant in question, fire protection systems for power plants may incorporate a number of tactics, including both passive (building features such as firewalls) and active (suppression) fire protection measures.

Industrial fire protection valves are designed to be robust, but even the toughest valve body can crack or break when subjected to the pressure exerted upon it from inside by the expansion of water as it freezes. In environments where freezing temperatures are likely or even possible, it is important to protect your deluge valves from this possibility. A number of solutions exist to protect deluge valves from freezing. Let’s explore the pros and cons of each.

A fire event can cause untold damage to property. But sometimes the extinguishing water can do as much damage to protected items as the fire itself. This includes such places as computer rooms, film archives, museums and other moisture-sensitive areas. In such areas where a false alarm can be catastrophic and the deployment of water should be restricted to the fire area alone, rather than the whole building or room, it can make sense to use a preaction fire protection system.

There are many ways to put out a fire. Depending on the situation, a fire protection system can be designed to work with various fire suppression agents. Plain water is commonly used because it is easily available and effective in many cases. However, water is not always the best choice. Other options include inert gases, dry or wet chemical agents, and different types of fire suppressing foam. In this post, we will discuss foam applications.

One of the many choices to be made in designing an industrial fire protection system is to determine the deluge valves operation philosophy in the event of a fire - manually or automatically. The next designing step for an automatic operation is how the pilot sprinklers with fusible plugs will be activated, pneumatically or hydraulically. The advantage of an automatic operation is that it takes place immediately in response to triggering conditions such as heat or flame, without need for human interference or decision making. This enables fast system response even in remote or unmanned locations.

When selecting a deluge valve for your fire protection system, one of the most important things to consider is flow capacity with low head loss. In a fire protection situation, every second is critical. It is essential for water/foam to reach the fire as soon as possible after the detection system is activated . Even a short delay can be catastrophic, especially where flammable materials are present. A valve’s specific design will affect both the volume and speed with which fluid can pass through the unit. These in turn have a significant effect on system performance, and on the eventual outcome should a fire event occur.

They say knowledge is power. And that is certainly true in fire protection. Knowing exactly what is going on in your fire protection system at any given time gives you vastly greater control. Reliable indication of the state of a valve can help diagnose problems, reduce system maintenance time, and improve performance and response time during a fire event.

Thankfully, tunnel fires don’t happen very often. But when they do, they can be catastrophic.

Fires can occur inside a tunnel, or be brought into the tunnel by a vehicle (for instance, due to friction, faulty electrical connections, or spontaneous combustion of cargo.) Tunnels are also sensitive to terrorist sabotage. Both roadway tunnels and train tunnels present the ideal conditions for a fire to get dangerously out of hand:
