additional 10% increments until the joint stops leaking, or until the measured torque value
reaches the maximum torque value of the bolts. Practical consideration for the integrity of
the liner often leads the user to distinct torque values to stop leakage due to the unique
combinations of flanges, bolts, gaskets, and sensor liner material.
Check for leaks at the flanges after tightening the bolts. Failure to use the correct tightening
methods can result in severe damage. Sensors require a second tightening 24 hours after
the initial installation. Over time, sensor liner materials may deform under pressure.
