HOSE ROUTING
1. Use elbows and adapters in the installation to relieve
strain on the assembly, and to provide easier and
neater installations that are accessible for inspection
and maintenance. Remember that metal end fittings
cannot be considered as part of the flexible portion
of the assembly.
2. Install hose runs to avoid rubbing or abrasion.
Clamps are often needed to support long runs of
hose or to keep hose away from moving parts. It is
important that the clamps be of the correct size. A
clamp that is too large will allow the hose to move
in the clamp causing abrasion at this point.
3. In straight hose installations allow enough slack in
the hose line to provide for changes in length that
will occur when pressure is applied. This change in
length can be from +2% to -4%.
4. Do not twist hose during installation. This can be
determined by the printed layline on the hose.
Pressure applied to a twisted hose can cause hose
failure or loosening of the connections.
5. Keep hose away from hot parts. High ambient
temperature will shorten hose life. If you cannot
route it away from the heat source, insulate it.
6. Keep the bend radii of the hose as large as possible
to avoid hose collapsing and restriction of flow.
Follow catalog specs on minimum bend radii.
