ANSI DIN Forged RF Rtj FF Class 1500 Carbon Stainless Steel Wn Weld Neck Flange

　　Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. When ordering a weld neck flange, it is important to specify the schedule pipe is being used for. This is because the inside diameter of the weld neck flange will match the inside diameter of your pipe. The buttweld joint weld neck flange has with the pipe along with the tapered hub, makes weld neck flange very resistant to dishing and a very sturdy connection. These weld neck flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.
