Alloy 20 Flanges

Manufacturer of ASTM SB462 Alloy 20 Blind Flange in India, at Factory Price


Alloy 20 Flanges


Alloy 20 Flanges Manufacturer in India, used in pipelines to close one pipeline. The connection can be permanent with welding or temporary with bolts and nuts. The 20 Alloy Plate Flanges, raised face flanges, ring type joint and flat face flanges are used differently in different application types. The material composition provides the flanges with high mechanical values. The Alloy 20 Slip On Flange has 551MPa minimum tensile strength, 241MPa minimum yield strength and 1443 degrees Celsius melting point. These values allow the flanges to be used in very high temperature services.

There are different types such as the welded neck raised face Alloy UNS N08020 WNRF Flanges. The raised face allows for maximum connection surface for bolts and nuts or welding. The flanges can sometimes have additional functions than just connecting two pipes. The Alloy 20 EN 1092-1 Reducing Flanges join the pipes together, as do all other flanges, but also, they decrease the diameter of the pipeline. The flanges can measured between ½ inches and 48 inches.

There are different pressure classes to the Werkstoff No 2.4660 Alloy Lap Joint Flanges ranging from 150 through 2500. The different pressure classes are based on the wall thickness and diameter of the flanges and are used in different pressure conditions. Various types of flanges that businesses involve in industrial applications like the Alloy 20 Lap Joint Flanges in the alloy 20 material are manufactured and supplied by Regal Sales Corporation.Alloy 20 Flanges Manufacturer in India, You can also get the details about different types of flanges such as the ASTM SB 462 Alloy 20 Slip On Flanges and others including price information.

What do you mean by Alloy 20 Flanges ?


Alloy 20 flanges are special industrial flanges manufactured from Alloy 20, a Ni–Cr–Mo steel. These flanges are famous for their excellent resistance on sulfuric acid and other corrosive chemicals and are quite used in the chemical processing, pharmaceutical and the food industries. It provides good strength, weldability and resistance to stress corrosion cracking thus makes it suitable on the above applications.

We are a reliable Alloy 20 Flanges Supplier in India, providing exceptional service to Oman, with delivered areas including UAE, Qatar, and United States.
