WebRecommended bolt torque sequence is shown in the following table. General Procedure Outline Once a flange is attached to the pipe or valve, the method of joining two flanges is as follows: Step 1: Piping runs joined to the flanges must be installed in a straight line position to the flange to avoid stress at the flange due to misalignment. WebThe correct method is to hand tighten the two-piece flange nuts, then tighten to the recommended torque with a (calibrated torque wrench). The lug nut MUST move 1/4 turn before arriving at final torque. Using 1” guns risk over-torquing. Over-torquing is just as damaging as under-torquing. Test drive.
