Stainless Steel Threaded Couplings, including half couplings and full couplings, are essential pipe fittings used to connect two pipes securely. Manufactured in accordance with ASTM A182 standards, these couplings ensure high strength, durability, and excellent resistance to corrosion. They are widely used in industries like oil & gas, petrochemical, chemical processing, and power generation due to their reliable performance in demanding conditions.
Carbon Steel Threaded Couplings and Alloy Steel Screwed Couplings are ideal for high-pressure applications, while Duplex Steel and High Nickel Alloy Couplings offer superior resistance to harsh and corrosive environments. These fittings are available in various forms, including half coupling, full coupling, and reducing coupling, providing flexible solutions for different pipeline requirements.
Threaded couplings are designed to join two pipes of the same or different sizes, allowing easy installation without welding. They are also used as repair couplings, as they can be fixed anywhere along the pipe length to prevent leaks. Manufactured as per ASME B16.11 and MSS SP-79 standards, they ensure precise threading and leak-proof connections.
Made from premium quality raw materials using advanced forging technology, these threaded couplings undergo strict quality testing for long-lasting performance. They can be customized in terms of material grade, size, and threading type to meet specific project requirements. Materials include stainless steel, duplex, super duplex, Inconel, Hastelloy, and copper nickel for diverse industrial applications.
These forged threaded couplings are exported to multiple countries, including Qatar, Bahrain, Saudi Arabia, Indonesia, United States, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, and Australia. The product range covers MSS SP-79 Threaded Coupling, Inconel Half Coupling, Copper Nickel Full Coupling, and Hastelloy Screwed Coupling, ensuring reliable and efficient pipeline connections across industries.
