RECOMMENDED ASSEMBLY AID
It is typically necessary to raise the flow line piping in order to
insert Ribs between union connections and the ground. Never
attempt to lift piping manually. The suggested method is to use
a “pipe jack”. A secondary method is to use a lever and fulcrum.
Place lever under flow line as shown and temporarily lift piping to a
minimal height using the following guidelines for reference:
a) Do not lift piping more than 6-8 inches. More than this increases
the potential of loosening the union seal connection.
b) Never extend any part of your body underneath the piping while
it is elevated.
c) Sometimes an opposing force is required from the side opposite
the lever. A second lever may be used.
d) Make sure that piping is still in straight line after lowering back
to ground. If piping or components are askew, there is potential
of leakage through union assemblies.
e) Do not lift piping while flow line is under pressure.
