Product Description

Your Trusted Incoloy 800 Flange Manufacturer & Supplier

TSM Technology Co., Ltd is a leading global supplier of Incoloy 800 Flange, known for its superior quality, reliability, and performance. Our strict quality control system ensures that every flange meets industry standards, offering excellent resistance to high temperatures and corrosion. With over 14 years of expertise, we provide customized solutions to meet your specific industrial needs.

What is the Incoloy 800 Flange?

Incoloy 800 Flange is a high-performance nickel-iron-chromium alloy flange designed to withstand extreme temperatures and corrosive environments. It is widely used in industries such as chemical processing, power generation, and petrochemicals due to its excellent strength, oxidation resistance, and metallurgical stability. This flange is ideal for applications that require heat and corrosion resistance, making it a reliable choice for various engineering and industrial processes.

Incoloy 800 flange supply types and specifications

Supply Type

Incoloy 800 flanges are available in flexible forms, mainly divided into:

Standard flanges:

Comply with international standards (such as ANSI/ASME B16.5, DIN/EN 1092-1), covering slip-on flanges, butt-welded flanges, blind flanges and other types.

Conventional sizes (DN15-DN1200, pressure levels PN6 to PN160) are available from stock, suitable for high temperature and high pressure pipeline systems.

Non-standard custom flanges:

Customize special specifications according to your needs (such as large-diameter flanges, special-shaped sealing surface designs or industrial-grade thick-walled flanges).

Support surface treatment optimization (pickling, sandblasting, electrolytic polishing) and pre-processing (surfacing nickel-based alloy sealing layer, precision drilling of bolt holes).

Materials and processes

Processing technology:

Free forging or die forging technology, combined with solution annealing (1150-1180℃ water quenching), eliminate residual stress and improve creep resistance.

During the finishing stage, the dimensional accuracy is controlled by CNC machine tools (tolerance ±0.1mm), and the sealing surface roughness reaches Ra≤3.2μm.

Quality inspection:

Ultrasonic testing (UT) detects internal defects, and penetrant testing (PT) or radiographic testing (RT) verifies surface and near-surface integrity.

Provide material certificates (EN 10204 3.1/3.2), heat treatment records and third-party inspection reports.
