China Incoloy 800 Forging Fittings Specifications

Incoloy 800, a nickel-iron-chromium alloy renowned for its exceptional high-temperature strength and resistance to oxidation, carburization, and corrosion, is particularly well-suited for forged fittings in industries like petrochemical, power generation, and aerospace.

The ASME B16.11 standard provides the benchmark for socket-welding and threaded forged fittings, outlining pressure-temperature ratings, tolerances, markings, and material requirements. This standard ensures reliability and compatibility in piping systems, with pressure classes typically including 2000, 3000, and 6000 for threaded fittings and 3000, 6000, and 9000 for socket-welding fittings.

In this blog post, I'll detail the China Incoloy 800 forgings under this standard, starting with a concise introduction to each type, followed by its dimension specifications in inches.

China Incoloy 800 Forging Types and Specifications

China Incoloy 800 Forging SW Fittings

The SW 90° elbow is a fundamental fitting designed to redirect fluid flow by 90 degrees in piping systems, minimizing pressure drops while maintaining structural integrity.

For Incoloy 800 forged 90° elbows conforming to ASME B16.11, they excel in high-temperature environments up to 1100°F, offering superior creep and rupture strength. These fittings are available in both socket-welding and threaded configurations, with dimensions tailored to nominal pipe sizes (NPS) and pressure classes to ensure precise fit and performance.

The Incoloy 800 45° elbow is to alter the flow direction by 45 degrees and is often used in applications requiring gradual turns to reduce turbulence and erosion. Incoloy 800 45° elbows under ASME B16.11 provide robust performance in sulfidizing atmospheres and are fabricated to tight tolerances for seamless integration in high-pressure systems.

Incoloy 800 SW Tees are branching fittings that allow for the division or combination of flow in three directions, essential for complex piping layouts. China Incoloy 800 tees per ASME B16.11 are engineered for durability in corrosive environments, ensuring leak-proof connections under varying pressures.

Incoloy 800 SW crosses provide four-way branching, facilitating multiple flow paths in tight spaces. Incoloy 800 crosses under ASME B16.11 offer high mechanical strength and are ideal for applications requiring uniform stress distribution.

NOTE:

1) The average of the socket wall thickness around the periphery shall be no less than listed above. The minimum values are permitted in the localized area.

2) In view of the tolerance of the outside diameter of the pipes, there is a possibility that the socket bore diameter is a little greater than what is specified in ASME B16.11.

3) In case the sizes of the connecting pipes differ from the corresponding ones listed, the actual sizes of the matching pipes shall be specified in the purchasing documents.

China Incoloy 800 Forging Cap and Coupling

Incoloy 800 caps seal the end of a pipe, protecting against leaks and contamination. Incoloy 800 caps in ASME B16.11 are forged for enhanced density and strength in end-closure applications.

Incoloy 800 Half couplings extend from one pipe end, often used for branching or instrumentation connections. Incoloy 800 half couplings per ASME B16.11 ensure compatibility with welding processes and maintain alloy properties.

China Incoloy 800 Forging Plug, Bushing

Incoloy 800 Plugs are used to close off openings in fittings or pipes, providing a temporary or permanent seal. Incoloy 800 plugs under ASME B16.11 are threaded for easy insertion and removal, with high resistance to pressure.

Incoloy 800 Bushings reduce the size of a threaded opening, allowing connection of different pipe diameters. Incoloy 800 bushings per ASME B16.11 are precision-machined for tight fits and long-term reliability in reducing applications.

Material Specifications and Selection

When specifying Incoloy 800 fittings, it is critical to adhere to the correct material standard:

Material Standard: ASTM B564 / ASME SB564.

Common Grades: UNS N08800 (Incoloy 800), N08810 (800H), N08811 (800HT). The "H" and "HT" grades have controlled carbon and aluminum/titanium content for enhanced high-temperature strength.

Key Properties: Typical tensile strength is 520 MPa, with a melting point of approximately 1385°C.

For your next project requiring reliable performance in demanding environments, specifying ASME B16.11 forged fittings in Incoloy 800 provides assurance of quality, durability, and safety.

Always ensure your supplier can provide proper mill test certificates to validate the material's chemical and mechanical properties.
