TCR Arabia in Saudi Arabia undertakes thermographic survey of installed thermal insulation on pipework and equipment when in service. The purpose of the inspection/survey is to verify by the measurement of surface temperature that the insulation materials have been applied in a thermally efficient manner, and that the insulation materials are conforming within the ambient conditions, operating conditions and the insulation specifications.
Work is undertaken in adherance to the codes specified in BS 5422, the use of thermal insulating materials and in BS 5970, thermal insulation of pipe work and equipment (in the temperature range minus 100°C to plus 870°C).
The survey is be carried out using fully portable infrared thermal imaging equipment with both “live” and “freeze-frame” recording facilities. All thermography equipment used is from Flir instruments utilizing thier latest FUSION functionality which allows for easier identification and interpretation of infrared images. This advanced technology enhances the value of an infrared image by allowing the technician to overlay it directly over the corresponding visible image. The functionality combines the benefits of both the infrared image ad visual picture at the push of a button. The thermography camera of TCR Arabia does this in real-time and the overlay function can be easily adjusted to suit any application such as electrical surveys, building diagnostics, and mechanical inspections.
The technician from TCR Aarabia that will be designated to conduct the survey will be fully trained in the operation of the thermal imaging equipment/recording equipment and shall be fully conversant with insulation systems and basic heat transfer physics. Technician will be trained in the analysis of results, identification of anomalies and shall prepare factual report of findings together with recommendations. The level of survey conducted and extent of reporting shall be dependent on the clients requirements, objectives etc., which can be determined prior to the survey commencing.
Prior to the site survey the client shall supply details of areas to be surveyed. Information wherever possible, shall include as a minimum:-
a) Line numbers/schedule.
b) Equipment numbers/schedule.
c) Operating temperatures.
d) Applied insulation specifications.
Where the survey requirement is only for the location of insulation faults or insulation breakdowns (hot or cold spots as applicable) information required need only be area involved and general indication of operating temperatures. During survey preparations TCR Arabia will liaison with the Client site engineer and suitable arrangements and dates for the site survey shall be made.
Documentation And Reporting Of Test Results
TCR Arabia's expert inspectors and technicans will on completion of the site survey document document all findings and recordings into the final report. Where applicable floppy disk images recorded during the survey will be enhanced and printed in the report. The video recording made during the survey shall form part of the report. All findings shall be summarized and the report shall recommend actions that need to be taken.
