Get a best quote for ANSI B16.11 Alloy 20 Flanges from Leading Manufacturer, Buy Carpenter 20 Flanges Weld Neck Flanges at Best Price in India.


Alloy 20 Weld Neck Flanges are oxidation and corrosion resistant materials, which is well suited for service in extreme environments subjected to high pressure and kinetic energy. When heated, these Alloy 20 Lap Joint Flanges form a thick and stable passivating oxide layer protecting the surface from further attack. Our Alloy 20 Ring Type Joint Flanges retains strength over a wide temperature range, and is attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. We provide these Alloy 20 Orifice Flanges at standard and customized sizes so as to one can choose accordingly.
