CPVC blind flanges provide a solid, bolted closure available across the full family of thermoplastic piping materials, including UPVC, CPVC, FRPP, PPH, and PVDF, giving plants a single sourcing point for chemical-resistant flanged closures.
Key specifications:
• Manufactured to DIN and GB standards, with round structure and flat face (FF) sealing surface matching standard flanged connection practice.
• Material options span UPVC, CPVC, FRPP, PPH, and PVDF, allowing the blind flange to be matched to the chemical compatibility and temperature requirements of the specific piping system it closes.
• 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 flanged fitting range.
• Available across DN15 to DN300.
• Injection-molded manufacturing produces consistent flange geometry and bolt-hole spacing for a reliable seal.
Sourcing blind flanges from a single multi-material product line simplifies inventory and specification for maintenance and engineering teams managing plants with several different thermoplastic piping materials in service.
Typical applications include sealing unused flanged branches on CPVC hot water and process lines, closing off spare equipment nozzles, and any flanged system requiring a removable, bolted closure.
