Threaded Flanges

A.B. Stainless Steel is one of the largest exporter, manufacturer and supplier of Screwed / Threaded Flanges in India. Screwed flanges are not suitable for circumstances including temperature or under cyclic conditions or bending stresses where leakage in the course of the threads may perhaps happen. Threaded Flanges are used for superior applications. They can be accumulated devoid of welding and can be used in very high pressure services, at or adjacent atmospheric pressure, where alloy steel is needed for power.

Available with us in various sizes and shapes, the offered flanges are used for scaffolding and fastener applications. Our Screwed Flanges / Threaded Flanges can further be customized in terms of thicknesses, sizes and specifications as per the specific requirements of our clients. We offer these flanges at market leading prices.
