What Is a Blind Flange?

Blind Flanges Are Used to Close and Open Pipelines. By Connecting the Flanges at the End of the Pipe with Bolts and Gaskets the Pipe Can Be Closed and Opened Quickly, Facilitating the Maintenance of the Piping System.

What Is HS Code For Blind Flange?

7307990000,7307910000,7307930000,7307210000,7307290000…..We Can Choose the Most Suitable HS Code for You Based on Your Usage and Your Suggestion, Which Is Convenient for Your Importation.Contact Us Now to Discuss.

Do Blind Flanges Need Gaskets?

Yes,We Need to Use Blind Flanges in Conjunction with Gaskets, Usually the Following Two Types of Gaskets:

  • Oval Gasket: Suitable for Medium Pressure, Dispersing the Pressure More Evenly.
  • Octagonal Gasket: Suitable for High Pressure System, Better Sealing Effect, Especially Effective in Preventing Leakage.
