Fire Fighting Steel Pipe Guide

Fire-fighting steel pipes are used in automatic sprinkler systems and other fire-fighting water supply systems. These pipes are usually painted red so that firefighters and others can easily identify them. and separate them from other water systems. This article will explain how fire piping works and the types used in fire suppression systems.

What Are the Common Fire Protection Systems?

There are some fire protection systems in common use around the world. Here are some of the systems we often see:

These include:

  1. Dry powder fire extinguishing system
  2. Deluge system
  3. Pre-action system
  4. Wet fire sprinkler system
  5. Gas fire extinguishing system
  6. Special hazard fire protection system
  7. Dry piping system
  8. Foam fire extinguishing system

The above commonly used systems can be divided into three categories: water fire extinguishing systems, gas fire extinguishing systems, and foam fire extinguishing systems.

Wet Fire Sprinkler System

Wet fire protection systems use sprinklers connected to the plumbing system. These sprinklers are automatic, and since they are always connected to the water system, once your water system is working, they are effective at putting out fires.

Whenever there is a fire, the sprinklers are turned on and the water is immediately drained. These systems are usually designed so that only sprinklers activated by the heat from the fire will spray water.

Dry Piping System

Dry plumbing systems also contain sprinklers that automatically activate in the event of a fire. However, these sprinklers are not connected to the plumbing system that is always connected to the water. Instead, piping systems contain nitrogen or air under pressure.

Dry piping systems have advantages in areas where the water in the piping may freeze. Activated sprinklers are activated by heat, so fires can be effectively extinguished without excessive water usage.

Deluge System

Deluge systems are used in areas where rapid fire damage is a concern. On warehouse loading docks, for example, this type of system is often used. Likewise, in tall buildings, the system is triggered by an alarm. The nozzle is always on and the alarm releases the water valve.

Preaction System

Preaction systems combine elements of wet and dry systems. The pipes will not release water until a fire is detected. The response time is fast, so these systems are often used in offices and commercial plazas.

Special Hazard Fire Protection System

Special Hazard Fire Protection Systems are suitable for areas where standard systems are not sufficient. They will detect and extinguish fires in these areas.

How Does a Fire Sprinkler System Work?

Fire sprinkler systems are an essential element of most commercial and residential buildings. In fact, they are a requirement for certain industries where fire risks may be higher than normal. They usually consist of a water supply system, a set of pipes and sprinklers for water distribution.

Fire sprinkler systems automatically discharge water, although they are not triggered by smoke. Once a fire is detected, they release enough water to contain the fire, so they are both a fire detection system and a fire suppression system.

High temperatures can trigger sprinkler systems because when a fire ignites, the air above it heats up rapidly. This rapid rise in temperature is not like the regular heat changes one would experience when cooking in a restaurant.

When hot air from the fire rises, it spreads along the ceiling. Each sprinkler is connected to a reliable water source, so when it is activated, the valve opens and pressurized water flows out.

What Types of Pipes Are Used in Fire Protection Systems?

Fire pipes are usually made of durable carbon steel and painted red for easy identification. However, these are not the only types of fire pipes available. There are also galvanized light walls that may have a silver exterior. Also available in CPVC and copper fire sprinklers.

Most red pipes are used in wet sprinkler systems. The galvanized pipe can be found in both dry and wet sprinkler systems. A preaction system as described above may also contain galvanized pipe.

You will find carbon steel pipes designed with different types of ends to suit your fire suppression system layout. For example, you can choose beveled, threaded, and grooved pipe ends.

Black steel is extremely heat resistant and durable, so once the pipes are installed, you won’t have to go back and replace them as often. You can expect that in the event of a fire they will be able to do what they are supposed to do.

Copper pipes do not corrode as fast as steel pipes, but over time some scale and pitting will appear. Sometimes a water softener may need to be used with copper pipes. Also, it is important to ensure that the pH of the water remains above 7 copper tube will not become brittle at low temperatures. Unlike thermoplastic fire hoses, they are lightweight and flexible.
