SS 430 Blind Flanges

The SS 430 Blind Flange (BLRF) is a solid, plate-like forging component used to seal the end of a piping system, valve opening, or pressure vessel. Unlike other flanges, it has no central bore, and its primary function is to terminate or isolate a pipe section, allowing for future expansion or maintenance access. Manufactured from Ferritic Grade 430 Stainless Steel (UNS S43000), these flanges are chosen for their good general corrosion resistance and outstanding oxidation resistance at elevated temperatures. Grade 430 is also magnetic. Zeron Fasteners produces these robust components using precise forging techniques, ensuring maximum material density and structural integrity required for high-pressure sealing applications. SS 430 Blind Flanges are critical in pressure testing, isolation points in pipelines, and wherever future pipeline shutdown or extension is anticipated, offering a cost-effective, durable, stainless solution.
