Riddhi Siddhi Impex is a leading manufacturer, stockist, and domestic supplier of Super Duplex Steel Threaded Tee (45° / 90°) in India. These fittings are designed to provide strong and leak-free connections in high-pressure piping systems. Manufactured from high-grade Super Duplex Stainless Steel (UNS S32750 / S32760), these threaded tees are ideal for critical applications in chemical processing, petrochemical, oil & gas, and marine industries. The superior mechanical strength and corrosion resistance of these fittings make them one of the most durable options for industrial systems..

The Super Duplex Steel Threaded Tee is a type of forged fitting used to combine or divide the flow of fluids. It features a “T” shape, allowing connection to three different pipes through threaded joints. These fittings are commonly available as Equal Tee and Reducing Tee, depending on the flow configuration. The use of threading ensures easy installation and maintenance, making it an ideal choice for systems that require frequent dismantling or inspection..

At Riddhi Siddhi Impex, each Super Duplex Steel Threaded Tee is manufactured in compliance with ASTM A182 / ASME SA182 standards, ensuring international quality and consistency. The tees are available in a wide range of sizes and pressure ratings (2000, 3000, 6000, and 9000 LBS). Our strict quality control process ensures dimensional accuracy, high performance, and a smooth internal finish for optimal flow characteristics...

Super Duplex Steel (UNS S32750 / S32760) offers an excellent combination of strength and corrosion resistance, particularly in chloride-containing environments. This dual-phase (austenitic-ferritic) material resists stress corrosion cracking, pitting, and crevice corrosion—making it suitable for use in harsh marine, offshore, and chemical plant environments. Its high yield strength also allows for weight savings and longer service life...
