After recommended torque has been achieved, perform a final tightening in a clockwise bolt-to-bolt

CHECK GAP BETWEEN BASE AND HOLDDOWN AFTER EACH TORQUE STEP. MAINTAIN AN EQUAL DISTANCE
BETWEEN COMPANION FLANGE FACES ON ALL SIDES.
8.
Experience has shown that, in some installation conditions, it may be necessary to re-torque the flange
bolting after the system has operated through normal pressure and temperature cycles. Under normal
operating conditions, the bursting disc is recommended to be replaced yearly. Severe operating conditions
may require that the bursting disc be replaced more often.
SEE APPENDIX A FOR STUD TORQUE VALUES
The holders are provided with strips (See figure 9) that can be folded and connected to ground the holder to the
flanges.
