SS 316L Slip-On Flanges

The SS 316L Slip-On Flange (SO) is a flat, ring-like forging that is designed to easily slide over the end of a pipe. It is secured by performing two fillet welds: one inside the flange bore and one outside. This double-weld configuration provides sufficient strength and integrity, making SO flanges a popular, cost-effective alternative to Weld Neck flanges in low-pressure, low-hazard services. The 316L designation ensures a low carbon content, which is crucial for preventing intergranular corrosion (sensitization) in the weld zones. The inclusion of Molybdenum provides superior corrosion resistance, specifically against pitting and crevice corrosion in environments containing chlorides, such as cooling water or saltwater applications. Zeron Fasteners manufactures and supplies reliable SS 316L Slip-On Flanges that conform to standards like ASME B16.5 and ASTM A182 F316L, offering ease of installation and long-term durability.
