A Duplex Steel Weld Neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.
What is Duplex Steel Weld Neck Flanges ? The Welding Neck Flanges (SUper Duplex WNRF) are often used for high-pressure applications. To order a Duplex Steel 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.
Duplex Steel Weld Neck flanges are used in applications where the conditions are severe and critical. Some of these conditions include high pressure, wide fluctuations in temperature and pressure, high temperature, fluids that are volatile and hazardous, and temperatures in the sub-zero range.
The long neck guides the pipe into the flange itself and provides reinforcement that a standard Duplex Steel Weld Neck flange cannot. Typically, the Duplex Steel long Weld Neck flange are the anchors for water-mains or sources of gas being pumped into a larger network of pipes, such as those in a factory or in an apartment building.
A Duplex Steel Weld Neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.
