ASTM B151 C70600 Copper Nickel Welding Neck Flange

Product Introduction

Forged Copper Nickel Welding Neck Flanges for Marine and Industrial Piping

C70600 Copper Nickel Welding Neck Flanges are manufactured from 90/10 copper-nickel alloy and designed for welded piping systems requiring reliable corrosion resistance and mechanical strength. The long tapered hub helps reduce stress concentration at the weld, making WN flanges suitable for pressure piping, seawater service and offshore installations.

Available in ASME, DIN and EN flange dimensions, these flanges can be supplied with Raised Face (RF), Flat Face (FF) or Ring Type Joint (RTJ) sealing surfaces according to project specifications.
