What Is Stainless Steel 304 Flanges?

Stainless steel 304 flanges are piping equipment that provide support to different piping items they connect as there is movement of media. SS 304 flanges are devices that are utilized in joining piping grades of different specifications. These flanges are designed with an outstanding 18/8 chromium and nickel content embedded in them. The 304 stainless steel flanges are available in different specifications allowing them to weld these components easily to respective modules. These flanges have enhanced strength and outstanding mechanical properties. ASTM A182 F304 grade covers standard forged specifications of fittings. These grades are designed to work in elevated temperatures and extreme pressures. The flanges can be availed across our outlets at the most reasonable prices.

Rishabh Steel Industries is a stainless steel 304 flange manufacturer in india, Established in 1997 and based in Mumbai. We Get ISO : 2009 quality management certificate in year 2014.

Stainless Steel 304 flanges

Top 4 Most Selling Types Of SS 304 Flanges

1.) The SS 304 slip on flange is one of the popular flange types in the industry. These flanges are slid on the piping equipment and welded using one or more fillet welds. They are preferred in low-pressure and temperature applications.

2.) A ASTM A182 F304 weld neck flange, on the contrary, is used in high pressure and temperature systems. This is as the long protruding hub present on the flange provides stability to the piping grade.

3.) The SS 304 blind flange doesn’t possess any hub or a lip. These flanges are versatile and are utilized to terminate the flow in the industry. They are generally bolted in place, allowing room for cleaning and maintenance.

4.) A Stainless Steel 304 socket weld flange is seen in small piping grades that have a socket opening allowing it to be easily attached to the items. These flanges are welded in place using a single fillet weld. They can be customized in different components as per project requirements.
