Weld Neck Flanges are designed to be butt-welded to a pipe, providing superior strength and integrity for high-pressure and high-temperature applications. The long tapered hub distributes stress and reduces stress concentration at the base of the flange.
Key Features:
• Superior strength for high-pressure applications
• Excellent for high-temperature environments
• Smooth bore minimizes turbulence and erosion
• Available in all pressure classes and sizes
Specifications:
• Size Range: DN15 – DN600 (1/2" – 24")
• Pressure Class: 150# / 300# / 600# / 900# / 1500# / 2500#
• Standards: ANSI/ASME B16.5, DIN 2633, JIS B2220, GB/T 9115
• Materials: 304, 304L, 316, 316L, 321, 310S, 904L, F51 Duplex
• Face Types: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ)
Applications:
Oil & gas pipelines, chemical plants, power generation, petrochemical industry, marine and offshore platforms.
