Types of Inconel Flanges We Manufacture

Our product portfolio covers the full spectrum of Inconel flanges, each designed for specific applications and operating conditions. Weld neck flanges are preferred for high-pressure systems due to their robust design and ability to withstand extreme temperature fluctuations. Slip-on flanges offer ease of installation and are widely used in lower-pressure applications. Blind flanges are essential for sealing off piping systems or pressure vessel openings, while socket weld and threaded flanges provide reliable connections for smaller diameter pipes.

We also manufacture lap joint, orifice, spectacle blind, long weld neck, and reducing flanges, as well as custom flanges based on client drawings and specifications. Our engineering team works closely with clients to ensure that every flange meets the precise requirements of their project, from material selection to dimensional tolerances.

Grades, Materials & International Standards

Material selection is a critical factor in flange performance, especially in corrosive or high-temperature environments. We offer Inconel flanges in a wide range of grades, each compliant with relevant international standards.

Inconel Grade Typical Applications Standards
