PVC-U/C Blind Flange for Industry

Key Features

• Solid construction: no center bore for complete sealing of flanged interfaces.
• One-piece injection: blind flange integrally molded for high strength with no leak paths.
• Flanged connection: bolted to mating flange with gasket seal.
• Chemical resistant: all PVC-U/C construction for corrosive industrial environments.

Manufacturing Process

One-piece injection molded solid flange from PVC-U/C. Flat flange face with bolt holes per standards. No center bore for complete sealing.

Critical Process Parameters

• Flange face flatness.
• Bolt circle and hole diameter conform to standards.
• Blind flange thickness meets pressure rating requirements.

Raw Material Characteristics

• Material: PVC-U or PVC-C
• PVC-U suitable ≤60°C; PVC-C suitable ≤93°C
• High mechanical strength and pressure resistance
• Chemical resistant

Typical Applications

• Permanent sealing of flanged pipe ends in chemical piping.
• Temporary isolation of flanged interfaces.
• Protective sealing of reserved interfaces.
• End capping during pipeline pressure testing.

Application Scenarios

• Sealing and isolation of flanged interfaces in industrial piping.
