Blind flange, also known as blind flange, is actually just a blind plate. It is a type of flange connection that lacks a hole in the center.

One of its functions is to seal the end of the pipeline, and the other is to facilitate the removal of debris from the pipeline during maintenance. As for the sealing function, it serves the same purpose as a pipe cap and a flange cap. However, pipe caps cannot be disassembled, while flanged blind plates are bolted on and can be easily removed. The materials for flanged blind plates include carbon steel, alloy steel, stainless steel, plastic, and more.
