Outstanding Mechanical Properties

Inconel 718 flanges excel under extreme conditions, offering a yield strength 1035 MPa and tensile strength of 1260 MPa. Their elongation ( 12%) and maximum hardness of Rockwell C35 ensure they accommodate stress and deformation, making them ideal for high-pressure and high-temperature environments.

Flexible Design and Application

These flanges are available in a wide size range (1/2 inch to 48 inches), different shapes, and custom dimensions per client requirements. Their face types (RF, FF, RTJ) allow use in versatile settings, while connections can be welded or threaded, enabling integration in complex systems.

Strict Compliance & Superior Finish

Compliant with global standards (NACE MR0175, ISO, DIN, ASTM B564, ASME SB564), each flange is manufactured using advanced forging techniques and finished with a smooth, nickel-plated surface. Packaging in wooden cases or pallets assures integrity during shipping.

FAQs of Inconel 718 Flanges:

Q: How are Inconel 718 flanges manufactured and finished?

A: Inconel 718 flanges are produced via forginga process that enhances grain structure and mechanical strength. After shaping, they receive a smooth, nickel-plated surface finish to protect against corrosion and wear. Strict quality controls are applied to meet ASTM B564 and ASME SB564 standards.

Q: What applications are best suited for these flanges?

A: These flanges are ideal for aerospace, petrochemical, power generation, and oil & gas industries. Their excellent weldability, high strength, and corrosion resistance make them suitable for both high-pressure and high-temperature environments where reliable performance is critical.

Q: When should I choose a specific face type (RF, FF, RTJ) for my application?

A: Select the face type based on the sealing and pressure needs of your system. Raised Face (RF) is common in most pressure classes, Flat Face (FF) is preferred where the mating flange is also flat, and Ring Type Joint (RTJ) is used for high-pressure, high-temperature applications demanding superior sealing.

Q: Where are these Inconel 718 flanges typically installed?

A: They are commonly installed in pipelines, vessels, valves, and process equipment within power plants, refineries, chemical facilities, and aerospace assemblies. Their corrosion resistance and mechanical properties are crucial in such harsh environments.

Q: What are the advantages of using Inconel 718 material?

A: Inconel 718 offers outstanding corrosion resistance, excellent mechanical strength, and stability at temperatures from -196C to 700C. Its high purity and nickel content (>99%) ensure prolonged service life and reliability in aggressive media and extreme conditions.

Q: How does compliance with standards benefit the user?

A: Compliance with international standards like NACE MR0175, ISO, and DIN ensures the flanges meet global safety, reliability, and performance requirements. This guarantees compatibility, traceability, and assures customers of consistent, high-quality products.

Q: What is the packaging process for these flanges?

A: After production and final inspection, flanges are securely packed in wooden cases or on pallets. This protects them from physical damage and environmental exposure during storage and transportation, preserving their quality and finish.
