Inspection And Maintenance - TLV SS3 Série Manuel D'utilisation

5. Piping Arrangement
Requirement
Install a catchpot with the
proper diameter.
Make sure the flow of
condensate is not
obstructed.
To prevent rust and scale
from flowing into the trap,
connect the inlet pipe
25 - 50 mm (1 - 2 in) above
the base of the T - pipe.
When installing on the
blind end, make sure
nothing obstructs the flow
of condensate.
Check to make sure that the pipes connected to the trap have been installed properly.
1. Has the piping work been done with the proper methods, as shown in the table below?
2. Is the pipe diameter suitable?
3. Has the trap been installed within the allowable inclination, with name plate or UP seal facing
up and with the arrow on the nameplate pointing in the direction of flow?
4. Has sufficient space been secured for maintenance?
5. Have maintenance valves been installed at the inlet and outlet? If the outlet is subject to
back pressure, has a check valve been installed?
6. Is the inlet pipe as short as possible, with as few bends as possible, and installed so that the
condensate will flow naturally down into the trap?

6. Inspection and Maintenance

Periodic operational inspections should be performed, at least twice per year or at intervals
according to use. Steam trap failure may result in temperature drop in the equipment, poor
product quality or increased losses due to steam leakage.
CAUTION
While the trap itself is maintenance-free, there may be other causes of malfunction, as
described in chapter 5 "Piping Arrangement" and chapter 7 "Troubleshooting". If the
corrective measures described therein do not solve the problem, the trap has possibly reached
the end of its service life and must be replaced.
Correct
Installation, inspection, maintenance, repairs, disassembly, adjustment
●
and valve opening/closing should be carried out only by trained
maintenance personnel.
Before attempting removal of the trap, close the inlet and outlet isolating
●
valves and wait until the trap has cooled completely. Failure to do so may
result in burns.
̶ 8 ̶
Incorrect
Diameter is too
small.
Diameter is too
small and inlet
protrudes into pipe.
Rust and scale
flow into the trap
with the
condensate.
Condensate
collects in the
pipe.
