Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub. Welded Pipe
Expander Flange is a Welding Neck pipe flange where the nominal size of the non-flanged end is larger than the nominal size of the flanged end. They can be used to change the size of a pipe run. These are usually used to increase the line size to the first or second larger size. This is an alternative to using a separate reducer and weld neck flange combination. The expander flange can be used to connect pipe to pumps, compressors and Valves. Pipe Flanges And Fittings
The NW Long Weld Neck Flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. Welded Pipes
