Carbon Steel Flanges Manufacturer In India

Check CS Flanges Price List And Large Diameter Carbon Steel Flanges Dimensions Chart.


Carbon steel flanges are durable, affordable, and can resist wear-and-tear. We are one of the top Carbon Steel Flanges Manufacturer In India, where you will get this pipe fitting in different sizes and dimensions. We produce CS Plate Flange of industry-approved standards like ASTM A694, ASTM A105N (SA105N), MSS SP-44, DIN 2533. Its accompanied pressure ratings lie between class 150 to 2500. The carbon content is vital in making flanges; as the element increases, the ASME B16.5 CS Pipe Flanges become more rigid and durable after heat treatment. In case of no heat treatment, an increased carbon rate would reduce the weldability. We produce the best quality flanges at competitive prices; you can see our costs in the Carbon Steel Flanges Price List.

We are one of the biggest suppliers of High Pressure Carbon Steel Flanges in India. The higher the class of flange, the more pressure it can handle. For example, a class 300 flange can take more pressure compared to a class 150 flange. We also have a good stock of Carbon Steel Lap Joint Stub Flange that consists of two components- a stub end and a loose backing flange. It is widely used in constrained spaces where frequent dismantling is required. We also supply and export Large Diameter Carbon Steel Flanges used to connect valves, pipes, and other equipment to form a pipeline.
