Stainless Steel Forging Welding Neck Flange
Welding neck flanges come in various sizes according to different standards such as ANSI (American National Standards Institute), DIN (Deutsches Institut für Normung), and JIS (Japanese Industrial Standards). The dimensions of the flange, including the outer diameter, bolt circle diameter, number of bolt holes, and neck length, are specified in these standards. The size of the flange is usually related to the nominal pipe size (NPS) it is designed to connect. For example, an NPS 2 welding neck flange will have a specific set of dimensions to fit a 2 - inch - diameter pipe.
