BOLT TIGHTENING
Extreme
care should be taken to see that locking devices are properly installed
and to see that bolts are properly tightened. It is recommended that
all in-tank fastenings be rechecked for tightness after the first 1500
hours of operation and subsequently at each scheduled shutdown. It is
imperative for proper bolt operation that all agitator shaft and impeller
bolts be torqued to values shown in the Torque Value Table, below:
