Apparatus for Corrosion Studies
Parr Instrument Company has designed a
vessel specifically to be used for long term (up
to 4000 hours) corrosion testing of zirconium
alloy samples in aqueous solutions near the
critical point of water.
The vessel illustrated is a non-stirred, fixed
head design with a volume of 3.7 liters with a
maximum working temperature and pressure
of 450 °C and 275 bar, respectively.
The vessel is heated with three clamp-on style
band heaters. Using an internal multipoint
temperature sensor, the system is capable
of maintaining a uniform temperature of ±
1 °C over a working zone of 30 cm centered
along the vertical axis of the vessel. A unique
control system, developed around the Parr 4871
Controller, is used to separately regulate power
to the three heaters.This ensures compliance
with tight temperature uniformity requirements.
Valves are provided on the head of the vessel
for purging with inert gas prior the start the test
as well as periodic sampling of the contents of
the vessel.The controller is equipped to record
temperature and pressure data for the duration
of the test.
