説明
Plastic region tightening has been applied to the flange joint assembly. The tightening procedure follows the modified HPIS flange tightening procedure, which employs the angle control method instead of the torque control method. Tightening tests is conducted using JPI 4 inch flanges and spiral wound gaskets. Bolts of M16 with the reduced shank are used to adjust the tightening force. The estimation method is proposed for the yield tightening force of the bolt with reduced shank of hollow cylinder. The scatter of the axial force is 10% or less after the tightening process is completed. The uniformity of the bolt axial forces obtained by plastic region tightening is equivalent or superior to that of elastic region tightening by HPIS procedure. In the tightening process, the increase in axial force is very small in the plastic region of the bolt, so that the influence of the elastic interaction is also small, which is advantageous with respect to the uniformity of the bolt axial force. Application of plastic region tightening to the flange joint may downsize the bolts and the flange due to higher tightening forces and their uniformity.
