Blank Flanges Blind Flanges

Blank flange or blind flange is connected to the flange at the end of the pipeline, and is a round plate with bolt holes that closes the pipeline. In order to prevent the rust and cracks on the surface of the stainless steel flange, the surface of the carbon steel flange is usually coated with an electroplating layer (yellow zinc, white zinc, etc.), or painted with anti-rust oil and sprayed with anti-rust paint.
