A Stainless Steel Forged Boss is a small but essential pipe fitting used for branch connections. Typically welded to the outside of a run pipe, it allows the attachment of instruments, sensors, or additional piping components. Manufactured through forging, these bosses provide high mechanical strength and excellent corrosion resistance, making them ideal for use in high-pressure and corrosive environments..

Riddhi Siddhi Impex offers Forged Bosses in a variety of stainless steel grades, including SS304, SS304L, SS316, SS316L, SS310, SS321, and duplex grades. These are manufactured according to ASTM A182 / ASME SA182 standards, with pressure classes of 3000#, 6000#, and 9000#. The forging process improves grain structure and tensile strength, while ensuring tight dimensional tolerances and excellent surface finish..

Stainless Steel Forged Bosses are widely used in industries that demand robust and leak-proof branch connections, such as oil refineries, chemical processing plants, water treatment facilities, power generation units, and offshore platforms. They are also used in high-temperature or corrosive piping systems, where reliability and longevity are critical. The high pressure ratings and forged integrity make them a reliable component in process piping systems..

Riddhi Siddhi Impex offers customized solutions including socket weld, threaded boss types, and size ranges starting from 1/8” to 4” or more on request. Finishing options include black, electro-galvanized, hot-dip galvanized, and pickled & passivated stainless surfaces.
