1 1/2 Inch Threaded Flange (ASME B16.5)

1 1/2 Inch Threaded Flange - Class 150 ASME B16.5 Forged Steel

 Product Overview The 1 1/2 inch threaded flange (also known as a 1.5" NPT flange) is a versatile piping component designed for systems where welding is not an option. Crafted from high-quality ASTM A105 forged steel, this flange is ideal for high-pressure applications in small-bore piping. As a critical part of our carbon steel threaded flange collection, it ensures a secure, leak-proof connection that complies fully with ASME B16.5 standards.

 Key Specifications

• Nominal Pipe Size (NPS): 1 1/2 Inch (1.5")

• Pressure Rating: Class 150

• Material Grade: ASTM A105 (Forged Carbon Steel) / Optional SS316L

• Thread Standard: NPT (National Pipe Thread) according to ASME B1.20.1

• Flange Face: Raised Face (RF) for enhanced gasket seating

• Manufacturing Standard: ANSI/ASME B16.5

Performance & Reliability Our 1 1/2 threaded flange is preferred for its ease of maintenance. The threaded design allows for quick assembly and disassembly, which is essential for systems requiring frequent inspection. For those operating in the Northern Rivers or Sydney Basin in Australia, or industrial sectors across Texas and North Carolina, these flanges provide a reliable mechanical joint that withstands the rigors of chemical processing, water treatment, and oil & gas utilities.
