Rajendra Industrial Corporation is a renowned Expander Flange Manufacturer, Supplier, and Stockist. A weld neck tube flange with a stainless steel expander is used to increase the tube size on the flange connection. The stainless steel expansion flange is a practical solution for connecting equipment, pumps, and valves if you have limited space or if you simply connect it to larger pipes. It can be used instead of a flange and a reducer. ANSI/ASME B16.5 pressure ratings and dimensions are followed. Stainless steel and carbon steel expansion flanges have a raised face.

The nominal size of the non-flanged end is bigger than the nominal maximum size of the flanged extremity, similar to the Welding Neck pipe flange. Pumps, compressors, and valves can all be connected to the pipe using the expander flange. A section of pipe can be extended using an expansion flange. These are typically used to increase line size to the first and second larger sizes. This is an approach to using a reducer and a weld neck flange separately.
