Audited Supplier A blind flange is a solid disk used to block off a pipeline or to create a stop. It is manufactured by Qingdao Wenli Shengfu Industry and Trade Co., Ltd.

The key difference between a blind flange and a regular flange is that a blind flange does not have an opening for fluids to pass through. This makes it ideal for applications where complete closure or isolation of a pipeline is required.
With its sturdy construction and reliable sealing capabilities, the blind flange offers several benefits:
