Stainless Steel Blind Flange is a precision-machined sealing component for industrial pipeline closure and isolation. Made from high-purity 304/316L stainless steel, its one-piece solid structure ensures excellent sealing tightness, corrosion resistance and long-term stability in complex industrial environments.
As a versatile end cap, it suits permanent closure and temporary isolation during maintenance, pressure testing or overhauls. Its precision-machined flat surface fits gaskets perfectly, preventing media leakage and external contamination.
Compliant with ANSI/ASME B16.5, DIN 2642 and EN 1092-1, our blind flanges cover various sizes, 150–2500 pressure classes and multiple surface treatments to adapt to different industrial media and conditions.
304 blind flanges are used in municipal water treatment, HVAC and light manufacturing. 316L variants, with molybdenum, resist chloride corrosion, suitable for chemical plants, marine equipment and oil & gas pipelines.
Each blind flange undergoes multi-step quality inspections (material purity, precision calibration, surface detection) to ensure pipeline compatibility and reliable sealing.
A core component in chemical, oil & gas, water treatment and manufacturing, it is trusted for reliability, easy installation and cost-effectiveness.
We offer standard and custom blind flanges, supported by professional technical consultation and competitive pricing, to provide tailored sealing solutions for your projects.
