Sagar Steel Corporation is a trusted Hastelloy Flanges Manufacturer that deals with high-grade flanges made of corrosion-resistant material such as Hastelloy stainless steel, galvanized alloys, and other high-performance materials. They have carefully designed flanges to achieve high industrial standards. With different shapes such as blind, slip-on, weld neck, and socket weld, they are leak-free and have very good stress distribution. Hastelloy Flanges are the most suitable applications in extreme chemical environments, high-temperature operations, and corrosive fluid systems. Hastelloy Flanges are typically used in construction, oil and gas, marine engineering, chemical processing, power generation, and agriculture piping systems. We also supply Inconel Flanges to meet additional industrial requirements.

Hastelloy Blind Flanges Hastelloy Blind Flanges
Blind flanges are solid discs without a bore, used to seal off the end of piping systems or pressure vessels. Commonly made from Hastelloy, they are ideal for maintenance access or system pressure testing in chemical and marine environments.

Hastelloy Weld Neck Flange Hastelloy Weld Neck Flange
This flange features a long tapered neck that provides excellent stress distribution, making it ideal for high pressure and high temperature environments. Manufactured using Hastelloy C22 or C276, it ensures resistance to pitting, crevice corrosion, and oxidizing agents. Commonly used in chemical processing, pollution control, and marine applications.
Frequently Asked Questions
What applications are best suited for Hastelloy flanges?
Hastelloy flanges are best suited for environments with extreme chemical exposure, high pressure, and elevated temperatures. Typical applications include reactors, heat exchangers, desalination units, petrochemical plants, marine systems, and flue gas scrubbers in power plants.
How durable are Hastelloy flanges under corrosive conditions?
Hastelloy flanges are highly durable and retain their mechanical integrity under aggressive chemical environments. Their resistance to pitting, crevice corrosion, and stress corrosion cracking ensures reliable performance in long-term industrial operations, even in extreme pH and temperature ranges.
Can Hastelloy flanges be customized for specific projects or large orders?
Yes, Hastelloy flanges can be customized based on size, pressure rating, face type (RF, RTJ), and alloy grade to match exact project requirements. They are ideal for large-scale orders through B2B channels, with bulk availability, fast lead times, and reliable global shipping.
