AS F91 threaded flanges and AS F91 spectacle blind flanges are supplied normally in tempered, normalized or tempered & quenched conditions. AS F91 welding neck flanges are giving very good services wherein resistance to general corrosion is quite essential.
The industry standards that our offered ranges of Alloy Steel F91 flanges are confirming are ANSI, ASME, EN, BS, and DIN, etc. It can be collected from us at different classes like 2500#, 1500#, 900#, 600#, 400#, 300# and 150#.
Certain applications where these flanges are used to a greater extent are petrochemicals, pharmaceuticals, oil & gas industry, food processing, seawater equipment, chemical industry, specialty chemicals, pharmaceutical industry, heat exchangers, condensers, power generations, pulp & paper industry.
The testing is done on all our produced ranges of Alloy Steel F91 flanges for checking how good the strength is. The tests are intergranular corrosion tests, hardness tests, PMI testing, pitting resistance tests, etc. The TC provided are EN 10204/3.1b, third party test report, radiography test report, and raw material certificates, etc.
