Titanium Weld Neck Flange (WN Flange) is a key connection component used in piping systems under high pressure,
high temperature, or harsh conditions. It features with a long neck transition section and is connected to the pipe
by butt welding, offering excellent strength and sealing performance.
Long neck titanium flange features with neck is relatively long, and is connected to the pipeline using a butt weld
interface, with a fully penetrating weld seam that has high strength. The gradual change in neck thickness effectively
disperses stress and reduces stress concentration at the pipe and flange connection. There are five types of sealing
surface, including RF,MFM,TG,FF,RJ .
Titanium flange with weld neck Flange has excellent anti-sag performance and can successfully cope with pressure
fluctuations, load cycles and impacts, they are versatile and suitable for a wide range of applications involving extreme
temperatures (high and low) as well as high-pressure environments. In terms of durability, the design of Titanium Weld
Neck Flange is flexible and long-lasting, offering a longer expected lifespan than other types of flanges because they
are less likely to deform under high temperatures and pressure.
