Sealing construction management method, seal construction management apparatus, seal construction management program, and sealing construction management system

摘要

A flange sandwiched between gaskets 12A plurality of fastening points are set inA sealing construction management method for fastening and fastening bolts (6) and nuts (8) at each clamping site;Fastening the bolt and nut with the fastening tool (14) with the first clamping torque value (T1) setDetecting the axial force of the bolt andA process for calculating or selecting the torque coefficient (K2) of the bolt using the detected axial force andFor each fastening point of the boltThe torque coefficient is calculated.Or, by selecting the selected second clamping torque value (T2) to the clamping toolFlange connection with high tightening accuracy can be realized.
