UPVC/CPVC Blind Flange

UPVC/CPVC blind flanges are high-performance pipe fittings widely used in industries such as chemicals, construction, and water treatment. They offer corrosion and high-temperature resistance, ensuring reliability in harsh environments.

Blind flanges are used to seal the ends of pipelines, preventing liquid or gas leakage and facilitating system maintenance and repair. Their lightweight design simplifies installation and handling, while their strong compatibility with other standard pipe fittings meets diverse project requirements.

The smooth surface of UPVC/CPVC blind flanges reduces fluid resistance, contributing to overall system efficiency.
