Weld Neck Flange

Weld Neck Flange (WN Flange) – High Pressure & High Temperature

Our Weld Neck Flanges are precision manufactured for critical piping systems requiring superior strength and reliability. The long tapered hub makes them ideal for high pressure, high temperature, and severe service conditions. The butt weld connection provides a smooth transition and excellent stress distribution.

Key Features:

• Material of Construction: Stainless Steel / Carbon Steel / Alloy Steel / Nickel Alloy
• Size Range: 1/2″ NB to 24″ NB
• End Connection: Butt Weld (BW)
• Pressure Rating: Class 150# to 2500#
• Design: Weld Neck Flange with raised face (standard)
• Benefits: Excellent resistance to high pressure, high temperature, and corrosion. Superior fatigue strength and easy alignment during welding.

Applications: Widely used in Oil & Gas, Petrochemical, Chemical Processing, Power Generation, Refineries, Fertilizer, and other heavy industrial piping systems where safety and leak-proof performance are essential.

These flanges are perfect for connecting pipes to valves, pumps, and other equipment in demanding process environments.
