Low Alloy Steel Flanges range in grades and dimensions. R.C. Metal Corporation produces some of the highest quality Chrome Moly Flanges and other alloy steel flanges. There are different classes and pressure capacities of these flanges. They range from ½ inches to 48 inches in nominal diameter and the specification is often ASTM A182 for pressure piping. The Alloy Steel Flanges Manufacturer in India are also used in piping systems to provide particular mechanical advantages. There are pressure classes ranging from 150 through 2500 and pressure number ranging from PN6 through PN64. The Alloy Steel Pipe Flanges range in type, function, shape and the face.
There are different face such as flat face, raised face and ring type joint flanges. The Alloy steel lap joint flange is a special type that it has a lap on it. The flanges are used in various industrial applications to hold the pipes together. There are different manufacturing types such as the Alloy Steel Forged Flanges, welded flanges, screwed flanges and threaded flanges. The different types are useful under different scenarios. The forged flanges are made from a single piece of raw material.
The Alloy Steel Threaded Flanges have female threads which are used to connect to pipes of male threads. The threaded flanges are good when welding and bolting are not possible or not necessary. The Alloy Steel Plate Flanges are used in oil and gas, offshore oil drilling, petrochemical, petroleum, power generation and many other industrial applications. The Alloy Steel Slip On Flanges are used mostly with seamless pipes for better positioning of the connection. Please feel free to contact us for the Alloy Steel Flange Material types, grades, different flanges and their prices.
