Description

Carbon Steel Weld Neck Flanges – ANSI B16.5, RF, Class 150/300

Description:

These Carbon Steel Weld Neck Flanges (WNRF) are manufactured according to ANSI/ASME B16.5 standards and are designed for high-integrity connections in pressure piping systems. The weld neck design features a tapered hub that provides excellent stress distribution through the weld joint, making them ideal for high-pressure, high-temperature, or cyclic loading environments. The flanges come with a raised face (RF) for gasket compatibility and are finished with a black anti-corrosion coating to ensure extended service life in demanding applications. Available in estimated sizes from 6" to 10", and likely pressure rated for Class 150 or 300, these flanges are widely used in oil & gas, petrochemical, power, and industrial piping systems.
