Incoloy 825 Pipe Fittings

Fittings such as elbows, bends, caps, tees, Incoloy 825 Reducer, lap-joint, and stub end made from austenitic nickel based Alloy 825 or alloy UNS N08825 is covered by the specification ASTM B366. Apart from substantial contents of iron & chromium, the alloy contains additions of molybdenum, copper and titanium.  Alloy 825 was developed to provide exceptional resistance to corrosion in both oxidizing as well as reducing environments. Incoloy 825 Pipe Fittings have a reputation for being resistant to chloride stress related corrosion cracking and pitting. We are leading Manufacturer and Supplier of ASTM B366 Alloy 825 Elbow. The addition of titanium in the alloy is what stabilizes Alloy 825 Tee against sensitization in the as-welded condition. Thus, making these fittings resistant to intergranular attack even after being exposed to temperatures in a range that would typically sensitize un-stabilized conventionally used stainless steel grades.

ASTM B366 UNS N08825 Fitting Reducer

The ASTM B366 UNS N08825 fitting reducer is a type of pipe fitting that is used to connect two pipes of different diameters, allowing for a reduction in pipe size. It is designed to ensure a smooth flow of the fluid or gas through the piping system while accommodating the change in pipe diameter.

These fitting reducers are manufactured in accordance with the ASTM B366 UNS N08825 standard specification, which ensures that they are made from high-quality nickel-molybdenum-chromium alloy material. This material provides excellent corrosion resistance and high-temperature strength, making it suitable for use in demanding industrial environments.

The dimensions of the ASTM B366 UNS N08825 fitting reducer will vary based on the specific size and type of reducer. They are available in a range of sizes to accommodate different pipe diameters and flow requirements. The specifications for these reducers will include details such as pressure ratings, temperature ratings, and material composition, ensuring that they meet the required industry standards.

ASTM B366 UNS N08825 fitting reducers are commonly used in industries such as chemical processing, oil and gas, petrochemical, and marine engineering. They play a crucial role in piping systems where the reduction of pipe size is necessary to maintain proper flow and pressure conditions.
