Fire Sprinkler Steel Pipe General Product Information

Fire sprinkler steel pipe is a type of pipe specifically designed for use in fire protection systems. These steel pipes are typically made of carbon steel and are used to distribute water or other fire suppressant agents throughout a building in the event of a fire. Fire sprinkler pipes are often installed in a network of pipes that are connected to a building’s fire sprinkler system. The steel pipes are manufactured to meet specific standards and regulations, such as ASTM A795 and ASTM A53, to ensure steel pipes reliability and effectiveness in fire protection applications.
