Alloy Steel Flanges are made up of different alloys that have different material compositions. Their mechanical properties vary with the composition and the dimensions vary with the standards. There are different types of alloys that belong to ASME A182 grades. The grades can range as F5, F9, F11 and so on. The Alloy Steel Blind Flanges are closed ended flanges that end a pipeline. There are different types of blind flanges and shapes for different types of applications. There are also other types such as socket weld flanges, weld neck flanges, SWRF flanges and Alloy Steel Slip On Flange types.

Chrome Moly Flanges
The slip on flanges are one of the most used types for the ease of application and the accuracy in connection point. The flanges range in sizes from ½ inches to 48 inches. The AS Pipe Flange dimensions are specified by the ANSI, ASME, ASTM, DIN and all other international standards. Depending on the need for mechanical properties, the high alloy or low alloy flanges can be used. The Low Alloy Steel Flange has low amounts of alloying elements where the high alloy flanges have higher amounts of alloying elements; sometimes, commercially pure elements as well. The different production types such as the Alloy Steel Threaded Flange, plate flange, screwed flange and the forged flanges are used in different types of applications. The applications include oil and gas, petroleum, water lines, high temperature services, low temperature services, chemical plants, food production plants, acid processing plants and other industrial applications.
