Flanges
Blind Flanges
Blind flanges are solid discs used to seal the end of a piping system, valve, or pressure vessel opening. They are subject to the highest bending stresses of any flange type due to the lack of a supporting pipe hub. Blind flanges are also used for future connections and inspection access points. Shree Raj Steels supplies blind flanges from 1/2" to 60" in Class 150 through 2500.
