This weld neck flange is designed for high-pressure, high-temperature applications requiring a robust and reliable connection. Manufactured to meet stringent ASME B16.5 standards and constructed from ASTM A182 Grade F53 duplex stainless steel, this flange offers exceptional strength, corrosion resistance, and longevity.

The raised face (RF) design provides a superior seal compared to flat face flanges. Weld neck flanges are designed to be butt-welded to a pipe system. The weld neck design helps to reduce stress concentrations at the base of the flange.
