Manufacturer, Supplier & Exporter of Duplex Steel Threaded Tee

Riddhi Siddhi Impex is a trusted and reputed name in the metal and pipe fittings industry, engaged in manufacturing and supplying high-quality Duplex Steel Threaded Tee products in India. As one of the country’s prominent manufacturers, stockists, and domestic suppliers, the company ensures that every Duplex Steel Threaded Tee conforms to international standards and offers unmatched performance. Designed for use in threaded piping systems, these tees provide easy assembly and disassembly while maintaining robust mechanical integrity...

The Duplex Steel Threaded Tee is a forged pipe fitting used to connect three pipes at 90-degree angles, allowing for smooth fluid or gas distribution in a pipeline. It is available in both equal and unequal (reducing) configurations depending on the application requirement. These fittings are made from high-quality duplex stainless steel grades such as UNS S31803, S32205, S32750, and S32760, which provide superior strength, excellent resistance to corrosion, and outstanding mechanical properties, even in harsh working environments.

Duplex stainless steel is a combination of ferritic and austenitic structures, giving it the best features of both categories. The Duplex Steel Threaded Tee exhibits twice the strength of conventional austenitic stainless steel, superior pitting resistance, and excellent resistance to stress corrosion cracking. Its high chromium, nickel, and molybdenum content ensures that it performs efficiently under high-pressure and corrosive environments such as those found in chemical plants, oil refineries, and marine industries..

Riddhi Siddhi Impex manufactures Duplex Steel Threaded Tees in accordance with ASME B16.11, ASTM A182, and ASTM A815 standards. The company uses modern forging, heat treatment, and machining techniques to produce fittings with high dimensional accuracy and durability. Each tee undergoes rigorous quality inspection, non-destructive testing (NDT), and pressure testing before dispatch. The fittings are supplied with complete material test certificates (MTCs) and can be customized as per client requirements..

As one of India’s leading domestic suppliers, Riddhi Siddhi Impex has built a strong distribution and supply network across major cities. The company supplies Duplex Steel Threaded Tees in Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, and Mysuru (Mysore).
