Some common materials used for fire protection systems fittings include:
Cast Iron
Durable, heavyweight iron commonly used for fittings like elbows, tees, crosses, reducers. Provides reliability in high pressure fire systems.
Ductile Iron
Stronger and less brittle than cast iron. Used for a wide variety of fire protection system fittings.
Steel
Used for fittings, pipes, and valves. Galvanized or black steel options. Provides high strength capabilities.
Copper
Corrosion resistant copper is used especially for sprinkler system fittings. Allows brazed connections.
Brass
Brass fittings used extensively in fire sprinkler systems. More expensive but very durable.
Bronze
Similar applications as brass for fire protection fittings but with greater strength.
Stainless Steel
Most resistant to corrosion. Often used for fittings in harsh environment fire systems.
Grooved Fittings
Fittings with grooved ends allow quick connection via coupling. Common in some fire systems.
Plastic
Durable engineered plastics used for non-metallic sprinkler system fittings. Lightweight.
The material is chosen based on factors like strength needs, corrosion resistance, pressure ratings, cost, and compatibility with the overall fire protection system.
