Ismail Flanges of Jakarta, Indonesia, is a top producer and supplier of Hastelloy Spectacle Flanges, providing corrosion-resistant, high-performance flow-control solutions for highly aggressive chemical and high-temperature applications. They have a dual-disc construction with one solid disc and one open disc welded together by a bridge, providing easy flow isolation during maintenance or inspection without disassembling the pipeline completely. Made in line with ASTM B564 and ASME B16.48 specifications, Ismail Flanges Hastelloy Spectacle Flanges find extensive application in refineries, petrochemical facilities, and offshore platforms.
Hastelloy Spectacle Flanges are usually constructed using grades such as C22, C276, and B2, which are nickel-based alloys renowned for their outstanding resistance to a broad range of corrosive chemicals. Such flanges have tensile strengths ranging between 690 MPa and 760 MPa and exhibit high resistance to oxidizing as well as reducing agents, including aggressive acids such as hydrochloric acid and sulfuric acid. Their mechanical strength as well as corrosion resistance is still effective even under high-stress, high-temperature operating regimes.
