SS 316 Blind Flanges

The SS 316 Blind Flange is a solid forging used to seal or terminate the end of a piping system, valve opening, or pressure vessel opening. Unlike other flanges, it has no bore, allowing it to act as a blank cover to block flow and facilitate future expansion or access. Due to its thick, solid nature, it is often utilized under high pressure and temperature conditions. Manufactured from Grade 316 stainless steel, these flanges incorporate molybdenum, giving them exceptional resistance to corrosion, particularly against chloride-induced pitting. Zeron Fasteners manufactures and supplies heavy-duty SS 316 Blind Flanges that comply with international standards like ASME B16.5, providing a dependable solution for complete pipeline isolation and termination.
