Pressure
Work tubes are not intended to accept high internal pressure. When gas
seals or similar fittings are in use, the gas pressure should be restricted to
a
maximum of 0.05 bar (50mbar)
. A pressure of approximately half of
that should normally be sufficient to achieve the desired flow rate. The
operator must ensure that the exhaust path from the tube is not blocked,
so that excess pressure does not occur.
l
A suitably regulated gas supply should always be used.
l
It is recommended that a pressure relief system should be used to avoid an over
pressurisation of the work tube.
Note:
A product should not be heated up if any valves that have been fitted are
closed to create a sealed volume. A sealed work tube should not be heated from cold
due to the pressure increase caused by the trapped air or gas expanding during the
heating process.
Note:
To minimise the increase of back pressure, always increase the
pipe diameter of any room vent lines when connecting to a product
exhaust outlet. For example, 6mm outlet connections should be
increased to a diameter of 10mm or greater for room lines between 5 -
10 metres in length.
Note:
Always maintain clean gas lines. Regularly inspect vent lines
connected to the exhaust outlet as any build up of debris may increase
the back pressure of the vessel/ work tube.
