An effective
way to remember this hose selection criterion is to
remember the
word STAMPED.
S = Size
T = Temperature
A = Application
M = Material to be Conveyed
P = Pressure
E = Ends or couplings
D = Delivery (volume)
Temperature (T)
When selecting a replacement assembly, two areas of
temperature must be considered. These are fluid temperature and ambient
temperature. The hose selected must be capable of withstanding the minimum and
maximum temperature of the system. Care must be taken when routing hose near
hot manifolds, and in extreme cases, a heat shield may be advisable.
Actual service life at temperatures approaching the recommended
limit will depend on the particular application and the fluid being
used in the hose. Intermittent (up to 10 percent of operating time) refers to
momentary temperature surges. Detrimental effects increase with increased
exposure to elevated temperatures.
