Stainless Steel Blind Flange is an essential sealing component engineered to terminate and seal industrial piping systems. Manufactured from high-grade 304/316L stainless steel, this blind flange features a solid flat structure, delivering superior leak-proof performance, strong corrosion resistance and lasting durability for diverse industrial scenarios.
As a specialized end cap flange, the stainless steel blind flange serves both permanent and temporary sealing needs—ideal for closing pipeline openings during maintenance, pressure testing, or system shutdowns. Its solid design forms a tight seal with gaskets, preventing media leakage and safeguarding piping systems from external impurities.
Our stainless steel blind flanges adhere to strict international standards (ANSI/ASME B16.5, DIN 2642, EN 1092-1), available in various sizes, pressure classes (150–2500) and surface finishes (pickled, passivated, polished) to meet diverse industrial piping sealing requirements.
The 304 stainless steel blind flange suits general industrial applications (water treatment, HVAC, light manufacturing), while the 316L blind flange provides enhanced corrosion resistance for harsh environments like chemical processing, marine engineering and oil & gas auxiliary pipelines.
Every stainless steel blind flange undergoes rigorous quality inspections, including material composition testing, dimensional accuracy verification and surface defect screening, ensuring seamless integration with piping systems and long-term reliable sealing performance.
Widely used in chemical, oil & gas, water treatment and manufacturing industries, the stainless steel blind flange is favored for its leak-proof reliability, easy installation and versatility, becoming an indispensable component for pipeline termination and maintenance.
We offer standard and custom stainless steel blind flanges, supported by professional technical guidance and competitive pricing, serving as your reliable partner for all industrial piping sealing needs.
