In electrical facilities, Steel Conduit Fittings play an important role in improving fire resistance.
Steel conduit fittings themselves have good fire resistance. Steel is a non-combustible material. Compared with some other plastic or metal conduit fittings, steel conduits will not burn or melt as quickly as plastics when a fire occurs, thus providing a reliable fire barrier for electrical lines and preventing flames and high temperatures from spreading to electrical equipment.
Its sturdy structure also helps fire prevention. Steel conduit fittings have high strength and hardness, can maintain their shape and integrity in a fire, and are not easily damaged by flames and high temperatures. This allows electrical lines to be continuously protected in a fire, reducing the risk of electrical short circuits and fire spread caused by conduit rupture or deformation.
The connection method of steel conduit fittings also has an important impact on fire prevention. Using reliable connection methods, such as welding, threaded connection, etc., can ensure that the connection between conduits is tight, prevent flames and smoke from entering the conduit through the connection, thereby improving the fire resistance of the entire electrical system.
Applying fire-retardant coating on the surface of steel conduits can further improve their fire resistance. The fire-retardant coating will expand when exposed to high temperatures, forming a thick insulation layer, which slows down the temperature rise of the steel and extends the effective protection time of the steel conduit in a fire.
