What Are Expander Flanges?
An Stainless Steel Expander Flange, generally referred to as EXPF, is similar to a weld neck flange. The only difference between a weld neck flange and an Industrial Expander flange is that the hub of the expander flange expands to a larger size. In fact, the ss expander flanges produced in our factory can be expanded to even two sizes larger.

Stainless Steel Expander Flange Connection To A Larger Pipe Size?
If you, are ever constricted by a limited space or if you just need a connection to a larger pipe size, using alloy steel expander flanges provides a convenient way to join equipment, pumps as well as valves. Further, using a carbon steel expander flanges can replace the use of both a flange and a reducer. Pressure ratings and dimensions for the API Expander Flange are kept in accordance with ANSI/ASME B16.5. As typical for the Hydraulic Flange Expander, this flange is manufactured with a raised face.

Properties of Stainless Steel Expander Flange include excellent corrosion resistance across a wide range of atmospheric environments, good machining properties, along with good resistance to oxidation corrosion. Expander Weld Neck Flanges can be used in intermittent service at a temperature which ranges to 870°C and if these flanges are used in continuous service, they can be used to an elevated temperature of up to 925°C. Duplex steel expander flanges have higher tensile strength at elevated temperatures, while having good resistance to carbide precipitation as well. As one of the leading expander flange manufacturers in India, we recommend these expander flanges to our clients mainly because duplex grade flanges tend to exhibit excellent weldability properties, both with and without the addition of filler metals to their alloys.
Expander Weld Neck Flanges can be used to change the size of a pipe run. These are mostly used to increase the line size to the first and second larger size. This is an alternative to using a separate reducer and weld neck flange both. A Stainless Steel Expander Flanges slide directly over the pipe and are most commonly used with stub end fittings.
Advantages of ASME B16.5 Stainless Steel Expander Flange are that its compact size saves space when compared to a reducer-welding neck flange. Only one butt-weld is needed in order to install the ANSI B16.5 Carbon Steel Expander Flanges cost effectively and competitively priced. The Exhaust Flanges Expander can be used to connect pipe to compressors, Valves and pumps.
