These fittings, available in sizes from 1/8″ to 4″, are designed for high-pressure applications with socket weld connections. They offer excellent resistance to oxidation and corrosion due to their high chromium and nickel content. Ideal for elevated temperature environments.
Threaded fittings in 321 stainless steel come in sizes ranging from 1/8″ to 6″. They provide superior resistance to intergranular corrosion, making them suitable for high-temperature and pressure applications. The threaded design ensures a secure, leak-proof connection.
This 45-degree elbow, available from 1/2″ to 4″, is used to change the direction of piping. It maintains high corrosion resistance and strength under elevated temperatures, making it suitable for critical, high-stress applications.
The threaded tee, with sizes from 1/8″ to 6″, allows for branch connections at a 90-degree angle. It is designed for high resistance to heat and corrosive environments, ensuring reliability and durability in demanding conditions.
Available in sizes ranging from 1/8″ to 4″, this half coupling provides a secure connection between two pipes. It is crafted to withstand oxidation and corrosion, making it ideal for high-temperature applications.
The socket weld cross, available from 1/2″ to 4″, connects four pipes at right angles. It features high resistance to thermal and chemical stresses, ensuring long-lasting performance in extreme conditions.
Stainless Steel 321/321H Forged Fittings have wide applications where high corrosion resistance and high temperature strength are essential. They find their applications in heat exchangers, chemical processing equipment, and exhaust manifolds where they can remain stable up to 870°C. These forged fittings are applied in the petrochemical, oil and gas, power generation, and aerospace sectors for seamless application in aggressive media. Their improved resistance to creep along with weldability makes them apt for piping systems, boilers, and superheaters. Apart from this, SS 321/321H fittings are also popular in food processing and pharmaceuticals industries due to their resistance against scaling and keeping purity in the hygienic environment.
