Quickly open the blind flange
Thread Content
Have you used quick-opening blind plates? I’d like to know what types of such products are available. Which type is best for use? Thanks!

Lock-ring type quick-opening blind flanges, GD blind flanges, etc.: There are vertical and horizontal types, I guess
Our medium is refined oil, and the blind flanges we use are from GD in the UK; they perform well. It’s just that the price of sealant ring spare parts is relatively high.
