Figure 9-52.-Hose assembly identification tags.

Obtain metal hose assembly identification
tags (fig. 9-52) from your local SIMA and
secure them onto one of the legs of the hose
configuration. The tag is made of a non-
corroding material. Do not remove or alter
the tag once it is attached.
Leave the configuration in a condition
where one end can hang down unsupported
during installation or dismantling of piping.
Otherwise, you can damage the hose wire
reinforcement.
Periodic Inspection By Ship’s Force
No less than once a quarter, preferably about
once a month, visually inspect all flexible piping
connections to determine whether any signs of
weakness or unusual conditions exist. Inspect the
hose in other systems semiannually. To assist you
when performing this inspection, you should
compile a checkoff list of hose assemblies and
locations for your assigned spaces or equipment.
This list will consist of all flexible devices
installed (and their locations) together with a list
of inspections to be performed on each flexible
device. When you perform the listed inspections,
note the following:

Evidence of leakage at fitting ends.
Discoloration of fittings (possible indica-
tion wire reinforcement is rusting).

(indicates weakening of bond between
outer rubber cover and wire braid or
deterioration of the reinforcing wire).
12.
Slippage of hose out of fitting.
Twisting of hose or other distortion or
unusual appearance.
Cracking of outer rubber cover.
Rubber cover rubbed thin by abrasion or
chafing.
High pulsations, fluid hammer, or whipping
caused by pressure pulsations.
Large vibrations due to improper supports
at the fixed end.
Large area of hose covered with paint.
(The intent of this requirement is to
eliminate having the flexible hose con-
nections deliberately painted. The hose
does not have to be replaced if a few paint
drops inadvertently fall onto it. Do not
attempt to clean off dried paint from the
hose.)
Check hangers to ensure they have not
broken off, become distorted, or been
otherwise damaged.
Soft spots or bulges on hose body
If results of visual inspection indicates
weakening of hose or fittings, or makes
hose configuration suspect, replace the
hose immediately, if at all possible. Keep
under surveillance while under pressure
until it is replaced.
