What is Long Weld Neck Flange?

Stainless Steel Long Weld Neck Flange

Stainless Steel Long Weld Neck Flange

ASME B16.5 Long Weld Neck Flange are often used for high-pressure applications. To order a Long Weld Neck Raised Face Flange, it is important to specify the pipe is being used for, 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. Stainless Steel Long Weld Neck Flange are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.
