Hastelloy Flanges are available in various grades containing nickel, molybdenum, chromium basing on their ratios of proportions. They are among the most flexible alloys that are commonly used for the fabrication of 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.
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% Ni, 14% Cr, 15% Mo with C, Mn, Si, S, Co, Fe and P in the content. It also has minimum tensile strength of 790MPa, minimum yield strength of 355MPa and melting point of 1370 degrees in Celsius.
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.
