Duplex Flanges Manufacturer in India widely used in oil gas offshore chemical processing and industrial pipeline applications
Sagar Steel Corporation is a trusted Duplex Flanges Supplier in India, which provides high-strength and corrosive resistant flanges to be used in the challenging piping and pressure-system jobs in industries. Duplex flanges are produced out of duplex stainless steel alloys which entail a combination of both austenitic and ferritic microstructures, which gives superior mechanical strength, high resistance to stress corrosion cracking and high reliability in the operation amidst aggressive service environments. They find extensive application in oil and gas, offshore, chemical processing, marine, desalination, power generation, and heavy engineering industry.
Being a reputable supplier in a global B2B portal, we guarantee that all duplex flanges are in accordance with any of the recognized international requirements i.e. ASTM, ASME, ANSI, DIN, and EN. It manufactures our flanges in different sizes, pressure ratings, and types of facing to enable purposes of making a safe and leak-free contact in high-pressure and high-temperature piping systems. High standards of quality control, checking of dimensions, and testing of materials guarantee uniform performance, extended service life, and compliance of the project.
