Expander Flanges

Expander Flanges Manufacturer

A welding neck pipe flange known as an Stainless Steel Expander Flanges is used to increase pipe size at the flange connection. It offers a practical way for machinery, pumps, and valves if you’re short on room or just need to connect to larger pipes. The use of a flange and reducer can be swapped out for the expander flange. The dimensions and pressure ratings adhere to ANSI/ASME B16.5. The face of this flange is elevated.

Our provided Expander Flanges are similar to welding neck pipe flanges in that the non-flanged end’s nominal size is greater than the flanged end’s nominal size. The pipe can be connected to pumps, compressors, and valves via the Expander Flanges. A pipe run’s size can be changed using an Stainless Steel Expander Flanges. Most commonly, these are employed to expand the line size to the first and second larger sizes. This serves as a substitute for both using a separate reducer and weld neck flange.

It is most frequently used with stub end fittings and slips straight over the pipe. The Expander Flanges, to which a pipe is typically welded, allows for free rotation of the stub end. The benefit of using an expander flange is that the alignment of the bolt holes won’t be an issue. The most of applications that require frequent dismantling use Stainless Steel Expander Flanges.

We at JK Engineering Works would like to take the opportunity to introduce as a leading Industrial Carbon Steel Expander Flanges Exporter in India. Stainless Steel Expander Flanges are stocked or available in the following range of materials and sizes for the oil, gas, petrochemical and allied industries. Pipes with Bleed Ring can be assembled and disassembled easily.
