Mstar Enterprises no need an introduction in the field of Flanges Manufacturing and supplying. We manufacture these flanges in various types, shapes, sizes, dimensions, forms, and material grades. With the use of high-quality raw materials and advanced manufacturing practices, we manufacture these flanges as per client requirements.

A Flange is one of the best piping equipment that used for connecting pipes, valves, pumps, and other equipment to make the piping system. Using flanges help to get easy access for cleaning, modification, and inspection. There are different methods that used to join two flanges with pipes like bolting and welding, etc.

Based on the joining methods, they into different types including Slip On Flange, Orifice Flanges, Spectacle Flanges, Lap Joint Flanges, Raised Face Flanges, Ring Joint Flanges, Weld Neck Flanges and Socket Weld Flanges, etc. All these types are manufactured with diverse material grades like Duplex Steel, Super Duplex Steel, Hastelloy, Monel, Inconel, Nickel, Carbon Steel, Alloy Steel, Stainless Steel Flanges, Cupronickel Flanges and more.
