Product Description

Stainless Steel Blind Flange



►Product Description

Stainless Steel Blind Flange is a high-performance sealing component specifically designed for industrial piping termination and closure. Crafted from premium 304/316L stainless steel, this blind flange boasts a robust solid structure, delivering exceptional leak-proof sealing, strong corrosion resistance and long-term durability across various industrial applications.

Designed as a specialized end cap, the stainless steel blind flange caters to both permanent and temporary piping sealing needs—perfect for closing pipeline openings during maintenance, pressure testing, or system shutdowns. Its solid flat design creates a tight seal with gaskets, preventing media leakage and protecting piping systems from external contaminants.

Our stainless steel blind flanges meet strict international standards, including ANSI/ASME B16.5, DIN 2642 and EN 1092-1, with a comprehensive range of sizes, 150–2500 pressure classes and surface finishes (pickled, passivated, polished) to fulfill diverse industrial piping sealing demands.

The 304 stainless steel blind flange is ideal for general industrial scenarios (water treatment, HVAC, light manufacturing), while the 316L stainless steel blind flange offers enhanced corrosion resistance, suitable for harsh environments like chemical processing, marine engineering and oil & gas auxiliary pipelines.

Each stainless steel blind flange goes through rigorous quality control inspections, including material composition testing, dimensional accuracy verification and surface defect screening, ensuring seamless integration with piping systems and reliable long-term sealing performance.

Widely applied in chemical, oil & gas, water treatment and manufacturing industries, the stainless steel blind flange is valued for its leak-proof reliability, easy installation and versatility, becoming a must-have component for piping termination and maintenance work.

We provide both standard and custom stainless steel blind flanges, supported by professional technical advice and competitive pricing, making us your trusted partner for all industrial piping sealing solutions.
