Recommended Installation Instructions For All styles

DO'S

•Inspect for damage during shipment, i.e. dents, broken
hardware, water marks on carton, etc...
•Store in clean dry area where it will not be
exposed to heavy traffic or damaging environment.
•Use only designated lifting lugs,
•Make the piping system fit the expansion joint by
stretching, compressing or offsetting the joint to fit
the piping, it may be overstressed when the system
is in service.
•It is good practice to leave one flange loose until the
expansion joint has been fitted into position. Make
necessary adjustments of loose flanges before welding.
•Install joint with arrow pointing in the direction of flow
•Install single Van Stone liners pointing in the direction
of flow. Be sure to install a gasket between the metallic
liner and Van Stone flange as well as between
the mating flange and liner.
•With telescoping Van Stone liners, install the smallest I.D.
liner pointing in the direction of flow.
•Remove all shipping devices after the installation is
complete and before any pressure test of the fully installed system.
•Remove any foreign material that may have become
lodged between the convolution.
•Refer to EJMA standards for proper guides.

DON'TS

•Do not drop or strike carton.
•Do not remove shipping bars until installation.
•Do not use hanger lugs as lifting lugs without approval
of manufacturer.
•Do not use chains or any lifting device directly on the
bellows or bellow cover.
•Protect with wet chloride-free asbestos.
•Do not use cleaning agents that contain chlorides.
•Do not allow weld spatter to hit unprotected bellows.
•Do not use steel wool or wire brushes on bellows
•Do not force-rotate one end of an expansion joint
alignment of bolt holes. Ordinary bellows are
not capable of absorbing torque.
•Do not hydrostatic pressure test or evacuate the system
before proper installation of all guides and anchors.
•Pipe hangers are not adequate guides
•Do not exceed a pressure of 1 1/2 times the rated
working pressure of the expansion joint.
•Do not use shipping bars to retain the pressure thrust
if tested prior to installation.

installation procedures have been used.
