Blind Flanges

Product Description

Blind Flanges are widely used in petrochemical, pipe engineering, public services and water works for attaching one pipe to another pipe safely. This flange is light weight with high tensile strength. Enormous resistivity towards moisture and adverse factors are the key attributes of our offered Blind Flange. These flanges are manufactured under the observation of our dedicated professionals with the help of progressive techniques. Our offered Blind Flanges are known for their unique features like corrosion resistance, robust construction and fine finish.
