Product Details
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 flange will match the inside diameter of your pipe. The butt-weld joint this flange has with the pipe along with the tapered hub, makes this flange very resistant to dishing and a very sturdy connection. These flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges. EO flanges offers these flanges in stainless and alloy material.
