Correct clamping (holding/supporting) of the hose
should be exercised to securely route the hose or to
avoid the hose contacting surfaces that will cause
the hose damage. It is however, vital that the hose
be allowed to keep its functionality as a “fexible-
pipe” and not be restricted from changing in length
when under pressure.
It should also be noted that hoses for high- and
low-pressure lines shall not be crossed or clamped
together, as the difference in changes in length
could wear the hose covers.
Hose should not be bent in more than one plane. If
hose follows a compound bend, it shall be coupled
into separate segments or clamped into segments
that each fex in only one plane.
Hoses should be kept away from hot parts as high
ambient temperatures shorten hose life.
Protective insulation may need to be used in
unusually high ambient temperature areas.
While the importance of the functionality is primary,
the aesthetics and practicality of the installation
should also be considered in the design.
Maintenance might be necessary at some point in
the future, so prohibitive design routings should be
avoided.
