For who doesn't know what are Traps and Heat's
Exchangers let's say that, sometimes, they are similar to see from a certain distance but,
in fact, what they have in common is only the external shape: both are composed with some
tubes circumferentially welded and a reducer near to the middle of the body. Their
purpose, instead, are completely different:
-
Traps are a couple of devices, one named Launcher and the other named Receiver,
made to be placed one at the beginning and the other at the end of a pipeline to be clean.
The Launcher will launch a "pig" by putting pressure behind it and the Receiver
will receive first the dirt collected by the pig and, after, the pig itself.
-
Heat's Exchangers are holders of an inside really complex system of small tubes
that, by using some chemical process, are able to reduce the temperature
of a certain
material (oil, etc.) in order to be better manipulated, stored or transported.
