iping Example: Flange Type Pressure-balancing Line
A screwed type flange may be installed on all models, as shown below.
The product is designed to continually and automatically discharge inflowing
condensate. However, if condensate completely fills the trap inlet piping,
displacement of steam and condensate becomes impossible. As a result, steam in
the trap body will not be able to escape thus preventing condensate from entering the
trap. This phenomenon is called steam locking. With a large difference between the
steam and the ambient temperatures, the steam flowing into the trap will eventually
condense and the steam locking phenomenon will be eliminated naturally.
When the steam trap inlet pressure is slight or negative, the difference between the
steam temperature and the ambient temperature is small. This increases the time
required to condense steam, making it difficult to resolve the steam locking. To
prevent steam locking, ensure steam escapes upstream so condensate can flow into
the steam trap.
Install the pressure-balancing line in the following manner:
Example: Heat Exchanger
Install the pressure-balancing line to a location where steam is present in both the trap
and the equipment or trap inlet piping.
