What are Inconel Flanges?

Inconel flanges are a special category of pipe fitting that forms a secure non-leak connection in all sorts of piping and equipment systems. These flanges are made of Inconel, a group of high performance, nickel chromium alloy that has a high strength with high resistance to corrosion. This is what makes them a perfect fit when it comes to applications of high temperatures, extreme pressures and harsh and corrosive environments. Our flanges are made with the rigorous ASTM B564 specification which ensures that it meets the best standards of forged and plate flanges in the industry.

The primary advantages of using Inconel flanges are their ability to resist oxidation, scaling, and cracking, even at elevated temperatures. Their excellent weldability also makes them easy to fabricate for specific requirements. As a leading inconel flanges manufacturer, we ensure our products have excellent weldability and can be easily fabricated to meet specific requirements. Due to these properties, Inconel flanges are essential in a wide range of high-temperature and high-pressure applications across key industries, including aerospace, chemical processing, power generation, oil and gas, and marine.

Frequently Asked Questions About Inconel Flanges

Inconel flanges outperform stainless steel in high-temperature and highly corrosive environments. While stainless steel is cost-effective for standard applications, Inconel offers superior strength retention at elevated temperatures, better oxidation resistance, and longer service life in harsh conditions. Industries such as aerospace, oil & gas, and chemical processing prefer Inconel flanges where stainless steel would degrade rapidly.

The correct grade depends on your application's specific demands — operating temperature, chemical environment, pressure rating, and industry standards. Each grade is optimised for different conditions. We recommend visiting our dedicated grade pages for a full technical comparison:
Inconel 600 Flanges — Best for resistance to chloride-induced stress corrosion cracking
Inconel 601 Flanges — Ideal for high-temperature oxidation resistance in furnace environments
Inconel 625 Flanges — Superior strength for marine, aerospace, and subsea applications
Inconel 718 Flanges — Designed for gas turbines, jet engines, and extreme temperature performance
Inconel 825 Flanges — Optimal for acidic, oxidizing, and sulfuric acid environments

All our Inconel flanges are manufactured as per ASTM B564 / ASME SB564 for the material standard, and dimensioned to ANSI/ASME B16.5, B16.47, B16.48, DIN, and BS specifications depending on the requirement.

Yes. We provide EN 10204 3.1 or 3.2 Material Test Certificates with every order. Optional third-party inspection reports from TUV, DNV, or Lloyd's Register are available on request for full traceability and quality assurance.

Inconel is a nickel-chromium superalloy primarily used for high-temperature and oxidation-resistant applications. Monel is a nickel-copper alloy best suited for corrosion resistance in seawater and reducing acid environments. For marine applications with saltwater exposure, Monel may be preferred; for high-temperature or heat-intensive industries, Inconel is the superior choice.

Yes. We fabricate custom Inconel flanges to customer-supplied drawings and specifications, including non-standard sizes, special face configurations, and custom pressure classes. Contact our technical team with your requirements for a detailed quotation.
