Stainless Steel 316 Flanges

Stainless Steel 316 Flanges

Arrow Piping Solutions is a leading manufacturer, supplier, and exporter of ASTM A182 Stainless Steel 316 Flanges in India. We offer a broad range of SS 316 Flanges Flanges including SORF Flanges, Socket Weld Flanges, Plate Flanges, Lap Joint Flanges, Threaded Flanges, and Spectacle Blind Flanges. These flanges are designed as per ASTM A182 / ASME SA182 specifications and other global standards such as ANSI, ASME, BS, EN, DIN, and JIS.

Stainless Steel 316 are austenitic alloys known for excellent corrosion resistance. SS 316 has higher carbon content, which makes it strong and ideal for acidic environments. SS 316 has low carbon, offering superior resistance to intergranular corrosion, making it perfect for high-temperature and highly corrosive conditions.

Arrow Piping Solutions manufactures SS 316 Flanges in various pressure classes, thicknesses, and dimensions to meet the demands of different industries. Our flanges are widely used in chemical, petrochemical, food processing, marine, pharmaceutical, power generation, and many other sectors.
