Weld Neck Flange

A weld neck flange is an industrial flange that has a long tapered hub. As an experienced flange maker in China, we at Yanshan are able to provide weld neck flanges that are quality built, durable, deformation free and have good sealing effect. Our weld neck flanges are widely used for pipelines which are subject to high pressure and extreme fluctuations of temperature.
