In modern industrial piping, the 2 inch threaded flange stands as one of the most versatile components. Known for its ability to create a secure, high-pressure seal without the need for welding, this threaded pipe flange is a staple in water treatment, oil processing, and chemical plants.
Why 2" is the "Sweet Spot" for Threaded Connections While larger pipes usually require welding, the 2 inch threaded flange offers the perfect balance between mechanical strength and ease of installation.
-
No Hot Work Required: Ideal for hazardous environments where welding sparks are a safety risk.
-
NPT Precision: Most 2 inch threaded flanges utilize NPT (National Pipe Thread) standards, ensuring a tapered fit that becomes tighter as it is torqued.
-
Versatility: Available in carbon steel threaded flange (A105) for durability or stainless steel for corrosion resistance.
Understanding ASME B16.5 Class 150 Standards When procuring a 2 inch threaded flange, it must comply with ASME B16.5. This ensures that the bolt circle, thickness, and thread engagement meet international safety codes. Whether you are ordering for a project in Florida or Sydney, standardizing on ASME B16.5 guarantees compatibility with other flanged pipe fittings.

Typical Applications
-
Water Utilities: Especially in the Northern Rivers region where rapid maintenance is key.
-
Chemical Refineries: In Texas and North Carolina, where 1 1/2 threaded flange and 2" sizes are used for instrumentation lines.
-
Marine Engineering: Utilizing stainless steel flanged pipe fittings to resist salt air in Gold Coast ports.
Installation Tip: Don't Over-Torque A common mistake with a threaded pipe flange is using excessive force. For a 2 inch threaded flange, hand-tighten first, then apply sealant and use a wrench for a final 2-3 turns to achieve a leak-proof seal.
