Flanges
Pavandeep Steel Center offers top-quality Duplex and Super Duplex stainless steel flanges designed for demanding industrial and offshore applications. These flanges provide exceptional mechanical strength, durability, and resistance to corrosion in harsh environments. Duplex flanges, such as grade 2205, feature a balanced austenitic-ferritic microstructure. This gives them higher tensile strength and superior resistance to stress corrosion cracking compared to conventional stainless steels.
Super Duplex flanges, including grade 2507, deliver even greater corrosion resistance and strength. They are ideal for highly aggressive conditions in chemical, oil, gas, and marine industries. Our flanges are available in various types, including weld neck, slip-on, socket weld, blind, lap joint, and threaded flanges. This ensures compatibility with different piping systems and applications. Duplex and Super Duplex flanges comply with international standards such as ASTM, ASME, and EN. Rigorous quality checks guarantee dimensional accuracy, surface finish, and mechanical properties. These flanges perform reliably under high pressure and extreme temperature conditions, making them suitable for pipelines, pressure vessels, and critical industrial processes.
