Which type of pipe is primarily used for water distribution in fire protection systems?

Steel pipe is primarily used for water distribution in fire protection systems due to its strength and durability. It is capable of withstanding high pressures, which is essential in fire protection applications where maintaining water supply and pressure is critical to effectively combat fires. Steel pipes also have a higher resistance to impact and structural stresses compared to other materials, making them suitable for the rigors of a fire protection system.

Moreover, steel is often preferred because of its ability to handle large volumes of water, which aligns with the need for rapid and reliable distribution during emergencies. It can also be easily welded or connected to other system components, further enhancing the overall integrity and reliability of the fire protection installation.

While other materials like PVC or CPVC can be used in some fire protection scenarios, they may not provide the same level of performance under extreme conditions as steel does. Galvanized pipe, although coated for corrosion resistance, is often considered less robust than uncoated steel pipe when subjected to high pressures or heat. Thus, steel pipe stands out as the most suitable choice for reliable and effective water distribution in fire protection systems.
