The Duplex Steel Threaded Elbow 45° / 90° is a type of forged pipe fitting used to change the direction of flow in threaded piping systems. Available in both 45-degree and 90-degree configurations, these elbows are designed for use in small-diameter pipes where welding is not feasible. Manufactured using duplex stainless steel grades such as UNS S31803, S32205, S32750, and S32760, these fittings offer outstanding resistance to corrosion, pitting, and stress cracking — ideal for high-pressure and corrosive environments..
Duplex stainless steel, used in Riddhi Siddhi Impex’s threaded elbows, combines the properties of both austenitic and ferritic stainless steels. This unique composition ensures high tensile strength, excellent toughness, and superior resistance to chloride-induced corrosion. The 45° elbow provides a smoother redirection of flow, while the 90° elbow allows for compact layout adjustments. The threaded connection design ensures easy assembly and disassembly, making it highly suitable for maintenance-intensive or temporary piping systems..
Riddhi Siddhi Impex manufactures Duplex Steel Threaded Elbows in compliance with ASME B16.11, ASTM A182, and ASTM A815 standards. Each fitting undergoes rigorous quality checks, including dimensional accuracy, pressure testing, and non-destructive testing (NDT). The company’s production process utilizes advanced forging and machining techniques to ensure precision, reliability, and long service life. Their commitment to consistent quality and timely delivery has made them one of the most preferred domestic suppliers of threaded elbows in India...
