Bolt-Tightening Sequence for
Water Piping Connections
This section describes a bolt-tightening sequence for
flanges with flat gaskets or O-rings. Remember that
improperly tightened flanges may leak.
NNoottee:: Before tightening any of the bolts, align the
flanges. Flange bolt torque requirements are
provided in the following table.
