Hastelloy Flanges Manufacturer In India


Hastelloy Flanges are made up of different type of nickel, molybdenum, chromium alloys that have different composition ratios. These are some of the most versatile alloys used to make flanges. The grades of Hastelloy vary as B3, X, C22, C276 and B2. Each of them have different mechanical properties and physical properties. The Hastelloy Blind Flange is used for close a pipe system by ending the line at one edge. These flanges can come under different specifications such as the ASTM SB564, 160 or 472. Each specification has a different use case.

DIN 2576 Hastelloy Alloy Flange

The standards of the flanges vary as ANSI, ASME B16.5, B16.48 and so on. There are flanges ranging from ½ inches to 36 inches in this grade of material. The Ansi B16.5 Class 150 Hastelloy Flanges are some of the low pressure class flanges where the pressure classes can range up to 2500 or from PN6 to PN64 pressure numbers. There are threaded flanges, screwed, forged or plate flange types. The DIN 2576 Hastelloy Alloy Flange has 50% nickel, 14% chromium, 15% molybdenum with carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in the composition. It also has 790MPa minimum tensile strength, 355MPa minimum yield strength and 1370 degrees Celsius melting point. There are different types such as the Hastelloy Socket Weld Flange, slip on flange and lap joint flange. Each of these flanges is used in different applications. The face of the flange can vary from flat face, raised face to ring type joint. The Hastelloy Weld Neck Flange has a welded neck which allows for the gripping of pipe inside the flange during and after the welding. The application of the flanges of this material grade can be seen in most high temperature, high pressure, high corrosive and high stress applications.
