Alloy Steel Flanges


ASME SA182 Grade F22 Blind Flange and ASTM A182 F11 Weld Neck Flange Manufacturer in India

Flanges are fixtures that are employed in connecting piping fixtures of different shapes and sizes. Alloy Steel Flanges are alloyed with different elements of alloys that are designed with a chemical content between 1 to 50%. The higher the content of alloys gives them higher strength and corrosion resistance properties. The Chrome Moly Flanges have good resistance to erosion and oxidation in different conditions. These flanges have outstanding toughness and possess good hardenability. They are easy to weld and fabricate to subsequent fixtures. A 4142 Chromoly Alloy Steel Flange has a density of .85 g/cm3 and has an elastic modulus of 190 to 210 GPa. These flanges are designed with a Brinell hardness of 230 max HB. They have a thermal conductivity of 42.6 W/mK. The Alloy Steel F22 Flanges have a low content of alloys that are employed to provide support to different piping fixtures during vigorous movement of fluids and gases. These flanges are quality-assured and produced with the best raw materials and latest technology by our renowned technicians.

The ASTM A182 F11 Slip on Flange is a versatile flange type in the industry. These flanges are manufactured as the flange is slid on the pipe fixture and is welded in place using one or more fillet welds. ASME SA182 Grade F22 Blind Flange is designed to work in elevated pressures and temperatures. These flanges don’t possess a protruding hub allowing them to terminate the flow in the system. They are mostly bolted in place, allowing room for repair and maintenance. The ASTM A182 F91 Socket Weld Flange is a forged flange that is seen in small piping fixtures. The flange is inserted in the socket of the flange and subsequently welded using a single fillet weld.
