6. Piping Arrangement
Allowable Inclination
Requirement
Correct
Incorrect
Install a catchpot with the
proper diameter.
Diameter is too
small.
Diameter is too
small and inlet
protrudes into pipe.
Condensate
collects in the
pipe.
Make sure the flow of
condensate is not obstructed.
When installing on the
blind end, make sure
nothing obstructs the flow
of condensate.
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.
Rust and scale
flow into the trap
with the
condensate.
Check to make sure that the pipes connected to the trap have been installed properly.
1. Is the pipe diameter suitable?
2. Has the trap been installed within the allowable inclination and with the arrow on the body
pointing in the direction of flow?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at inlet and outlet? If the outlet is subject to
back pressure, has a check valve been installed?
5. 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. Has the piping work been done with the proper methods as shown in the table above?
