Incoloy 825 Flanges are manufactured using NiCr alloy which constituent 38Ni,19Cr, having carbon,manganese, silicon, sulfur, copper, iron,aluminium and titanium as stabilizing elements. In this case, the Incoloy UNS N08825 Pipe Flanges are available in various sizes proportional to their size and standard. In this case, flanges vary with type as slip on flanges, weld neck flanges, socket weld flanges, and blind flanges. The material has tensile strength of 550 MPa, minimum yield strengths of 220 MPa and elongation rate of 30 % at the temps varying from 20°C to 350°C.
The Incoloy 825 Slip On Flanges are used in precision applications along with seamless pipes. The material of the flanges has high density and 1400 degrees Celsius melting point. Incoloy 825 Flanges Manufacturer in India, The specification for the flanges of this grade of material is the ASTM B564 and the standards vary as ASME B16.5, ASME B16.47 series A and B, and other international standards as well. The Inconel 825 Long weld neck is a weld neck flange with a long neck. This type of design helps to hold larger pipe sizes in place during welding.
The flanges range from ½ inches to 60 inches with various wall thicknesses. Depending on the flange dimensions the pressure classes of the DIN 2.4858 Socket Weld Flanges and others vary from class 150 to class2500. There are PN16 through PN64 pressure numbers associated with the pressure classes as well. The Incoloy UNS N08825 Threaded Flanges, screwed flanges, plate flanges and forged flanges are produced through different manufacturing techniques.
