Steelage Alloys is a trusted name among the top Slip On Stainless Steel Flange suppliers and manufacturers in India, delivering high-quality flanges to domestic and global industries. Our Slip On SS flanges are fabricated using premium-grade stainless steel such as SS 304, 304L, 316, 316L, 321, and Duplex Steel, offering excellent corrosion resistance, durability, and dimensional accuracy. These flanges are widely used in pipeline systems for oil & gas, chemical, petrochemical, water treatment, power generation, and marine applications.
A Slip On flange (SO flange) is a ring-type flange that is slipped over the pipe and then welded from both inside and outside to provide strength and prevent leakage. It is ideal for low-pressure and low-temperature applications where quick installation and alignment are required.
