摘要： FLANGE FASTENING MANAGING METHOD, FASTENING MANAGING SYSTEM, FASTENING MANAGING PROGRAM, AND FASTENING MANAGING DEVICE The present invention consistently manages gaskets and 5 fastening conditions from selection to execution by associating them to flanges, to thereby achieve high reliable flange fastening management and reducing the worker's burden. According to the present invention, in a flange fastening managing method, a computer (controller 6) as well as a fastening tool (4) are used. The 10 fastening tool fastens flanges with a gasket (14) by a plurality of bolts and nuts. The gasket is sandwiched between the flanges. The method comprises the steps of acquiring fastening condition information associated with the flanges (12); acquiring gasket information conforming to the flanges; collating the gasket 15 information with gasket information acquired from the gasket, to determine whether the gasket fits the flanges; and applying a fastening torque from the fastening tool to the bolts or the nuts under a fastening condition acquired from the fastening condition information when the gasket selected fits the flanges. 20 Fig. 1
