1. (Amended) A pipe inspection system (30) arranged
upstream from a pneumatic equipment (20, 22, 24) in a direction
in which compressed air flows in order to inspect whether there
is a compressed air leakage location at an inspection target
portion (32) of a pipe (16) that supplies the compressed air to
the pneumatic equipment (20, 22, 24), the pipe inspection
system comprising:
a first branch pipe (34) that branches from the pipe at a
location upstream from the inspection target portion and merges
into the pipe;
a fluorescent solvent supply portion (40) that is
provided for the first branch pipe and supplies a fluorescent
solvent (44) to the inspection target portion;
a second branch pipe (46) that branches from the pipe at
a location downstream from the inspection target portion; and
a fluorescent solvent collection portion (52) that is
provided for the second branch pipe and collects the
fluorescent solvent from the inspection target portion,
wherein the second branch pipe and the fluorescent
solvent collection portion are arranged upstream from the
pneumatic equipment.
2. The pipe inspection system according to claim 1,
wherein the fluorescent solvent supply portion includes a mist
generator (42) that turns the fluorescent solvent to mist, and
the mist of the fluorescent solvent is supplied to the
inspection target portion.
3. The pipe inspection system according to claim 1
or 2, wherein the fluorescent solvent is an aqueous solution or
an aqueous emulsion of a fluorescent agent.

WE CLAIM:
4. The pipe inspection system according to claim 1,
further comprising:
a first valve (36) that is provided for the pipe between
a location where the first branch pipe branches and a location
where the first branch pipe merges;
a second valve (38) that is provided upstream of the
fluorescent solvent supply portion in the first branch pipe;
a third valve (48) that is provided in the pipe
downstream of a location where the second branch pipe branches;
and
a fourth valve (50) that is provided upstream of the
fluorescent solvent collection portion in the second branch
pipe.
5. The pipe inspection system according to any one
of claims 1 to 4, further comprising a discharge portion (56)
that is provided downstream of the fluorescent solvent
collection portion in the second branch pipe and is open to the
atmosphere.
6. The pipe inspection system according to claim 1,
further comprising a black light (62) that irradiates the
inspection target portion with ultraviolet light.
