The 2" Threaded Pipe Flange (ASME B16.5 Class 150) is often called the "utility size" of the piping industry. Compact yet robust, this specific dimension is the standard for countless modular systems. Because it utilizes A105 Forged Steel, it offers the mechanical strength required for industrial environments while maintaining the convenience of a 2" NPT standard connection.
1. Fire Protection and Sprinkler Systems
In fire protection, speed and reliability are non-negotiable. The 2 inch threaded pipe flange is frequently used in pump room manifolds and standpipe systems.
-
Why Threaded? It allows for rapid on-site assembly without the fire hazards associated with welding in existing buildings.
-
Material Choice: The A105 forged steel construction ensures the flange can withstand the high-pressure surges typical of fire pump activation.
2. HVAC and Chilled Water Loops
Large-scale commercial HVAC systems rely on 2-inch lines for secondary cooling loops.
-
Integration: A 2 inch NPT flange is the perfect interface for connecting chilled water pumps, heat exchangers, and strainers.
-
Maintenance: Since HVAC systems require periodic descaling and component replacement, the threaded connection allows technicians to easily "break" the pipe joint without heavy machinery.
3. Oil & Gas Modular Skids
For chemical injection or fuel gas conditioning skids, space is at a premium. The 2" A105 carbon steel threaded flange is the preferred choice for connecting meters, valves, and regulators to the main header.
-
Safety: Using a Class 150 A105 flange provides a verified pressure rating that meets international safety codes for hydrocarbon service in low-pressure utility lines.
4. Water Treatment and Irrigation
From desalination plants to industrial irrigation, the 2" forged steel flange provides a rugged connection point for PVC-to-Metal or HDPE-to-Metal transitions. The precision-cut NPT threads ensure a leak-proof seal even in outdoor, high-vibration environments.
Conclusion
Whether you are building a fire suppression system or a complex chemical skid, the 2" Threaded Pipe Flange provides a reliable, standard-compliant solution. Choosing ASME B16.5 Class 150 A105 Forged Steel ensures your project is built on a foundation of quality and safety.
