Forged Flanges

Class 600 Forged Flanges Exporter, Alloy Steel Forged Flange, Duplex Steel Forged Flange, Class 300 Forged Flanges, Class 150 Forged Flanges, Stainless Steel Forged Flanges, Nickel Alloy Forged Flange, Carbon Steel Forged Flange, Forged Flanges Supplier In India.

These Flanges are made by using alloys like carbon steel, alloy steel, stainless steel, etc. The properties of the forged flanges is dependent on the type of material used in its construction. It has enhanced mechanical as well as physical properties. Because of the duality in their microstructure these flanges made from duplex variety of stainless steel. Also, it shows properties like excellent resistance to corrosion resistance, excellent tensile strength, good hardness and toughness properties. Besides these properties, the flanges have good weldable and machining properties.These shows features like corrosion resistance, durability and high tensile strength.
On this flanges the main anti-corrosion or anti-rust oil treatment is applied. These Forged Flange can also be galvanized. The Galvanization with zinc element is increases the corrosion resistance of the Forged Flange. The Flanges manufactured in a high pressure and high temperature working environment as the performance of a Forged flange is good in an elevated pressure and temperature environment. These flanges are used in pipe and tubing systems. Its used in metalworking and enginerring for joining pipes, valves, pumps, and the other equipment so that they can work smoothly as one unit. They offer advantages being able to connect different types of materials together. Also, it allow flexibility for removed or rplaced needed components. A flange can have female ends where it would receive bolts from another component and the male end where it could connect to another component.
