INDUSTRIAL PPH BLIND FLANGE

Industrial PPH blind flanges provide a solid, bolted closure engineered for PPH piping systems, extending PPH's high-temperature chemical resistance to closure points in industrial 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 suited to installations that may need to be reopened.
• Standard PN10 pressure rating matches the pressure class of the broader PPH flanged fitting range.
• Available across DN15 to DN300.
• Injection-molded manufacturing produces consistent flange geometry and bolt-hole spacing for a reliable seal against the mating flange gasket.

In elevated-temperature process systems, a removable bolted blind flange offers a practical advantage over a welded cap where the closure point may need periodic access for inspection or future connection, since it can be unbolted without disturbing the pipe.

Typical applications include sealing unused flanged branches on hot process lines, closing off spare nozzles on chemical processing equipment, and industrial PPH systems requiring a removable, bolted closure.
