ASME SB366 Incoloy 925 Buttweld Pipe Bend Fittings Specifications

Renowned Manufacturer of Incoloy 925 Elbow (1D, 1.5D, 3D, 5D, 10D), U Bend, Piggable Bend, Hot Induction Bend, UNS N09925 Long & Short Stub End, Lap Joint Stub End.

Incoloy 925 is a nickel-iron-chromium alloy with significant additions of molybdenum, copper, titanium, and aluminum. This composition enhances its mechanical strength and corrosion resistance properties. It is specifically engineered to withstand aggressive environments, including those containing sulfuric and phosphoric acids. Incoloy 925 is known for its resistance to stress corrosion cracking and oxidation at elevated temperatures, making it a suitable material for applications in industries such as oil and gas, marine, and chemical processing where durability and reliability are paramount.

The manufacturing of Incoloy 925 buttweld equal and unequal tees begins with the selection of high-quality raw materials based on specific alloy composition requirements. These materials are heated and shaped into tee forms using hydraulic presses or hammers. Welding processes such as TIG (Tungsten Inert Gas) or submerged arc welding securely join the components. Depending on application needs, heat treatment processes may be employed to enhance mechanical properties. Finally, tees undergo rigorous inspection for dimensional accuracy and surface finish, including treatments like pickling or passivation for improved corrosion resistance.

Incoloy 925 buttweld fittings undergo rigorous inspection processes post-manufacturing to ensure adherence to strict quality standards. This includes comprehensive checks for dimensional accuracy, surface finish, and mechanical properties, ensuring they meet exact specifications for reliable performance in demanding environments. Following inspection, the fittings are meticulously packaged using materials that safeguard against corrosion and physical damage, such as plastic wrapping, foam inserts, and robust boxes. Clear labeling with essential details like part numbers and sizes facilitates easy identification and handling, ensuring the fittings arrive in optimal condition for installation in critical applications across industries requiring high corrosion resistance and durability.
