Super Duplex Flanges manufactured in India for offshore oil gas chemical processing and high pressure pipeline systems
Sagar Steel Corporation is a trusted Super Duplex Flanges Manufacturer that provides high-strength and corrosion-resistant flanges made from premium super duplex stainless steel. These flanges exhibit excellent mechanical properties, superior pitting and stress corrosion cracking resistance, and are roughly twice as strong as standard austenitic stainless steels. Designed for demanding applications, they are widely used in offshore, marine, oil & gas, and chemical processing industries. With a balanced ferritic-austenitic structure, these flanges perform exceptionally well in high-pressure, high-corrosion environments. We also supply Alloy Steel Flanges to meet additional industrial requirements.
The modern industrial market has simplified sourcing super duplex flanges using interfaces in the B2B marketplace and ensured it is more reliable and efficient. These flanges can be completely customized to suit face type, pressure rating, and dimensional requirements for demanding applications. Their scalability to large orders makes them suitable for large-scale infrastructure projects, undersea works, desalination, and chemical processing plants. These flanges have strong logistics and global distribution and provide reliable operation, long service life, and quality stability in challenging industrial processes
