Wuxi ABK hydraulic welding rotator and welding automation equipment for heavy-duty vessel fabrication, supporting ASME Section VIII Division 3 / U3-stamp high-pressure vessel and hydrogen storage weld workflows.
ASME Section VIII Division 2 is the design-by-analysis alternative to Div 1, using detailed stress/fatigue/fracture analysis and tighter documentation to support ASME U2-stamp pressure vessels with 15–30% wall-thickness reduction for refinery, petrochemical, LNG, aerospace and SMR applications. Wuxi ABK welding automation—HGZ rotators, manipulators, positioners and digital-twin/machine-vision QA with calibrated parameter logging—supports Div 2 welding quality, 100% NDE, PWHT/toughness and U2-stamp documentation chains.
ASME B16.9 is the dimensional and pressure-temperature rating standard for factory-made wrought butt-welding fittings including elbow, tee, reducer, cap, and cross. This guide covers material specifications, welding considerations, and Wuxi ABK equipment (HBJ positioner, HGZ rotator, ZHGK fit-up, TTW orbital) for pressure vessel nozzle, process piping, and pipeline spool fabrication.
