Acceptance test and acceptance test report
▪
After completion of the installation work (before installation of the thermal insulation) each heating circuit must be accepted, if possible in the
presence of the client.
▪
All further tests must also be documented in an acceptance test report (refer to section
Acceptance report / Record of inspection
on page 40
).
NOTICE
Claims under warranty will not be considered if the acceptance report is not filled in completely.
▪
After completion of work on the thermal insulation final inspection and acceptance of the individual heating circuits is recommended. Usually,
this is the task of the client or the final customer (= final inspection).
Commissioning
Each heat tracing system can only be put into operation if the following conditions are fulfilled:
▪
The acceptance test reports for each heating circuit are complete and the trace heating system has been accepted.
▪
All components of the heating circuit are completely installed and are in working order.
▪
It has been ensured that the heating circuit is operated in conformance with the technical data specified by BARTEC.
NOTICE
Upon a cold start, additional heating power is required for heating up tanks and pipes. When starting the system you should allow sufficient time
for heat up. For further information on heat up calculations contact your local BARTEC representative.
Operation
During operation of the electric trace heating system you must ensure that all components of the system are operated within the operating data
specified by BARTEC.
This applies particularly to observation of the maximum temperature. Operation within these operating data is a precondition for possible later
warranty claims.
System documentation
Complete documentation must be carried out for each system, from the project planning stage, through installation and commissioning up to
periodic maintenance of the trace heating system.
This documentation should include the following:
▪
Project planning documents
▪
Manuals of all of the components of the heating system
▪
Heat loss calculation
▪
Selection of the trace heater
▪
Layout plans with division of heating circuits
▪
Circuit graphs
▪
Acceptance reports
▪
Reports on repairwork and any operations carried out on the tank/pipe system, trace heating system and thermal insulation
▪
Inspection reports
Maintenance
Visual and functional inspection
▪
Regularly check the thermal insulation for possible damage, missing seals, cracks, damage to the outer jacket, missing thermal insulation bushings
for trace heaters and cables, penetrated water or chemicals. If the thermal insulation is damaged the trace heater should be checked for possible
damage.
▪
Damaged trace heaters must be replaced.
▪
Parts subject to wear must be replaced (e.g. seals, locking plates etc).
▪
Check junction boxes, splices, end terminations etc. for corrosion and possible mechanical damage. Make sure that all enclosure covers are
properly in place.
▪
If present, check the temperature controller connecting cables and sensors for damage and that their installation is protected against mechani-
cal damage.
Electrical inspection
▪
Measurement of the insulation resistance should be seen as a permanent part of regular maintenance. For instructions on how to perform the
test refer to section
Measurement of the insulation resistance
on page 36.
