What is weld neck flanges?
The Welding Neck Flanges (WNRF) are often used for high-pressure applications. To order a weld neck flange, it is important to specify the pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe or Fitting. The buttweld joint this flange has with the pipe along with the tapered hub makes this flange very resistant to dishing and a sturdy connection. 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.
