specified when ordering spare parts. For cross-
sectional drawings and parts lists, see the next

inspection proceDUre
spray nozzle assemblies (1) and (2) and
fastener rings (5) shall be considered wear
parts. The materials selected are such that
they do cope with the conditions as found on
applications in steam/water environments.
Thermal cycling does occur and users should
realize that the temperature differentials at
desuperheaters are usually the highest found
in the plant. It is advised to check the spray
nozzle assembly, with the integrally vacuum
brazed injection nozzles, fastener ring and
tack-welds after the first year of service.
at the inspection, by use of dye check or fluor
penetrant investigation, these parts shall be
checked for cracks. parts with hair crack
indications shall not be re-used. 'defect-free'
heads in such installations shall be inspected
once per 2 year of operation.
It is advised to replace the above mentioned
components at least once per 5 years of
service. Taking these precautions has
historically proven to give reliable service.
note: spray nozzle assemblies may have been
made specifically for the specification. delivery
time of such components will be 8 weeks.
storage proceDUre
upon receipt, check both the Que - Temp
desuperheater and the packing case for any
transit damage. any damage to the Que - Temp
desuperheater should be reported immediately
to yarway or their local agent. any damage to
the packing container should be rectified to
prevent the ingress of dust or water, prior to
placing the equipment into storage.
Check the information contained on
the identification plate - tag plate and
documentation and return the unit to its
packing with protective covers in place.
For short term storage, up to 6 months
duration, no additional preservation
measures are necessary. retain the unit
in its original packing in a clean, dry indoor
location. If outdoor storage is unavoidable,
then the packing case should be enclosed
in a waterproof covering.
For long term storage use only a dry indoor
location. ensure that the Que - Temp
desuperheater is dry and free from moisture.
apply a cosmoline type grease to machined
faces. retain Que - Temp desuperheater in
its original packing and inspect at 3 monthly
intervals to ensure that no deterioration has
occurred.
