Flanges are pipe fittings that are used to connect pipes or fittings together to perform different functions. They have a raised part so that they could be attached well to the other component either by welding or by bolting. Mild Steel Flanges are common in usage as they provide a medium range of strength and corrosion resistance in a balance. Dinesh Industries is a Mild Steel Flanges manufacturer in India and the production includes various types of MS pipe flange component. There are different types of materials used for different applications. There are also different methodologies producing the flanges. The Cast iron flanges are used in applications that prioritize strength over corrosion resistance.

There are also different functionalities of the flanges we make. Our MS blind flange is used in applications that require a closure of pipes. In locations where the connection has to be sealed water tight, the MS puddle flange can be used. It seals the ends of both pipes inside the flange part. There are different standards such as the mild steel flange ANSI B16.5 which has flanges of ½ inches to 24 inches with varying pressure capacities. The MS plate flange is used to provide an additional surface of attachment. Our mild steel forged flange parts are used in heavy welding applications. You can also contact us to know more about our products.
