Fire fighting pipe is a kind of normal carbon steel pipe for conveying water, gas and other fire suppression agents. It's usually in red. But the exterior of the light-wall pipes is galvanized silvery. The installation of a red steel pipe is only to be used as a wet sprinkler system. Dry and wet pipe sprinkler systems (including pre-action pipe sprinkler systems) are allowed to install galvanized pipes.
Since the installation of the first fire protection system, black steel has been the traditional leader of the fire sprinkler pipe market because of its strength, durability, and extreme resistance to heat exhibited. With a melting point between a whopping 2,600°F and 2,800°F (1,427°C and 1,538°C), steel pipe can withstand the heat of burning buildings, it even can keep water flowing over a fire.
Fire suppression pipes are easy to form, bend, and fabricate, which can be manufactured in various sizes, shapes and configurations. Steel pipe has been the main material of sprinkler piping systems for a long time. Steel is considered strong, durable and resistant to fire. With a melting point of about 2,700°F, the fire service pipe can withstand the heat of a burning building.
Steel fire sprinkler pipes can be connected by screw thread, welded connection, rolling connection and groove cutting connection. Threading is only allowed for Schedule 40 or heavier pipe. However, if a lighter wall pipe is listed by a specialized thread testing laboratory, NFPA 13 (National Fire Protection Association) will allow the lighter wall pipe threads.
