UPVC Blank Flange with Thread Hole for Water

Key Features

• Threaded hole design: central threaded hole allows installation of instruments or valve accessories.
• Sealing function: serves as a blank flange to close flanged interfaces.
• One-piece molding: blind flange and thread integrally molded for high strength.
• Corrosion resistant: all-UPVC construction, maintenance-free.

Manufacturing Process

One-piece injection molded from UPVC. Flange face is flat; central threaded hole formed during molding or machined afterwards. Bolt holes per standards.

Critical Process Parameters

• Flange face flatness.
• Central thread dimensional accuracy and form.
• Bolt circle and hole diameter conform to standards.

Raw Material Characteristics

• Material Composition: UPVC. Central thread may have brass insert for enhanced strength.
• Material Properties: Consistent with series.

Typical Applications

• Sealing of flanged pipe ends.
