SS 304 Blind Flanges

The SS 304 Blind Flange is a solid, circular plate without a center bore, designed to terminate or close off the end of a piping system, valve, or pressure vessel opening. It is a critical component used for isolating flow, especially during maintenance, inspection, or when a pipeline extension is planned for the future. As a forging product, the blind flange ensures maximum pressure containment and sealing capacity across the entire face. The SS 304 material, with its high chromium-nickel content, provides excellent general corrosion resistance and good performance in non-chloride industrial and utility applications. Zeron Fasteners manufactures and supplies high-quality SS 304 blind flanges to strict dimensional and pressure-rating standards (ASME B16.5), ensuring reliable and leak-proof sealing capability for safe system closure.
