Proper Installation - TLV L Serie Einbau- Und Betriebsanleitung

5. Proper Installation

CAUTION
NOTE: For socket weld connections, use electric arc welding with a single pass. As internal parts
are not damaged by one-pass welding there is no need to remove them before welding.
1. Horizontal installation (nameplate showing up) is recommended, vertical installation is possible.
The arrow on the trap must point in the direction of flow. DO NOT install trap on its side or
upside down.
2. Before installing the steam trap, blow out the inlet piping to remove all dirt and oil.
3. Install a bypass valve, and inlet and outlet valves for maintenance or trap failure situations.
4. Install the trap in the lowest part of the pipeline or equipment so the condensate flows into the
trap by gravity. The inlet pipe should be as short and have as few bends as possible.
5. Install a check valve at the trap outlet of L21S, L32S whenever the condensate discharge pipe
leads to a tank or recovery line; or whenever the condensate collection pipeline is connected to
more than one trap.
6. Support the pipes within 0.8 meters (2.5 ft) on either side of the trap.
7. In order to avoid excessive back pressure (the outlet back pressure should be no more than
90% of the inlet steam pressure), make sure the discharge pipes are large enough;
8. The use of unions is recommended to facilitate connection of the screwed version.
6. Piping Arrangement
Requirement
Install a catchpot of 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.
• Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.
• Take measures to prevent people from coming into direct contact with
product outlets.
• Do not use excessive force when connecting threaded pipes.
• Install for use under conditions in which no freeze-up will occur.
• Install for use under conditions in which no water hammer will occur.
Correct
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.
