High quality PVDF blind flanges provide a solid, bolted closure engineered for PVDF piping systems, extending PVDF's exceptional chemical resistance and purity to closure points in ultrapure and highly aggressive process installations.
Key specifications:
• Manufactured to DIN and GB standards, with round structure and flat face (FF) sealing surface matching standard flanged connection practice.
• Flanged connection allows the blind flange to be bolted directly onto a mating pipe flange, valve, or equipment nozzle, providing a removable closure.
• Standard PN10 pressure rating matches the pressure class of the broader PVDF flanged fitting range.
• Available across DN15 to DN300.
• Injection-molded manufacturing produces consistent flange geometry and bolt-hole spacing for a reliable seal.
For high-purity PVDF systems, a bolted blind flange allows closure points to be reopened for future connection without cutting into the pipe or introducing potential contamination from a welding operation on an already-installed high-purity line.
Typical applications include sealing unused flanged branches in semiconductor ultrapure water systems, closing off spare nozzles on pharmaceutical process equipment, and PVDF systems requiring a removable, bolted closure.
