ASME B16.47 A182 F91 Lap Joint Flange Class 2500 - Large Diameter Alloy Flange

Produced by Dingxiang Jinyu Forging, this flange strictly complies with ASME B16.47 standard, crafted from premium A182 F91 alloy steel. Boasting exceptional high-temperature resistance, anti-creep and oxidation performance, it excels in harsh working conditions like thermal power, nuclear power and petrochemical high-pressure pipeline systems. With Class 2500 ultra-high pressure rating and large-diameter design, it meets the demand for large-flow, high-pressure medium transmission. The lap joint structure enables flexible rotation and easy alignment, reducing installation difficulty and improving construction efficiency. Precision forging enhances structural density and load-bearing capacity, while 100% non-destructive testing ensures zero defects. It’s a reliable choice for global high-end industrial projects requiring durable, high-performance large-diameter flange solutions.
