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 for reliable sealing.
- Corrosion resistant: all-UPVC construction, maintenance-free.
Manufacturing Process
One-piece injection molded solid UPVC flange. 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
