When an outlet needs to be closed a blind flange is usually the part that’s needed to make sure everything is sealed off properly.

Blind Flange Construction

Blind flanges are usually made from AISI 4130, but they can be made from different types of material upon request. Heshka Oil offers blind flange sizes ranging from 1-13/16” to 7-1/16”. The pressure ratings for each blind flange are from 2,000 PSI to 15,000 PSI.

Another component that Heshka Oil offers is the conversion of blind flanges into test flanges. This is done by drilling and tapping either a ½” NPT port or 9/16” autoclave port into the top or side of the flange. The port depends on the pressure rating required.
