A blind flange is a safety device used to isolate equipment or lines when they need to be inspected or taken out of service. This unique flange is designed to temporarily or permanently shut off a pipeline for maintenance, repair, or modification without interrupting the flow of fluid or gas.

Spectacle shutter thickness is specified based on line pressure and pipe size. Changhao manufactures a wide range of high-quality blind flanges in China. We supply flanges to ASME/ANSI/DIN standards.
