Venkata Ramana . In reply to elevated film based radiography. Yes conventional RT can be carried out at elevated tempratures, but cooled cassettes must be used to avoid film damage. Air cooled cassettes have been used very succesfully. These are made up by sandwiching the film between aluminium sheets, and passing chilled air over the sandwich layers. Film identification and pich marks are positioned on the front face of the aluminium sheets to avoid direct contact with the piece under examination.

Venkata Ramana . Just a suggestion for your elevated temp X-ray. If geometric unsharpness or object to film distance is not a concern a 1.00" layer of Kayo Wool and strips of corrugated cardboard could do the trick. Use a "J" tube if possible. You will also have to work fast.
The Athena Phased Array system, manufactured by WesDyne NDE Products & Technology, consists of a pha
sed array acquisition system and PC running IntraSpect software. A PC is used to perform acquisition, analysis and storage of the data. System hardware is capable of operating up to four data sets with any combination of phased array or conventional UT probes. NOW AVAILABLE IN 64-64 CONFIGURATION.
Representing the seventh generation of the IRIS system, the IRIS 9000 Plus has nearly 200 years of c
ombined field inspection experience incorporated in its design. This experience combined with a strong commitment to quality and a history of innovation has made Iris Inspection Services® the undisputed leader in IRIS technology.
Teledyne ICM’s CPSERIES has been designed with a view to
revolutionizing the handling and perfor
mances of portable X-Ray
sets. Despite having managed to halve the weight of similar
portable X-Ray generators available on the market (while
continuing to provide the same power output), the SITEX CPSERIES
generators feature a shutter, a laser pointer, a beryllium window,
an aluminum filter and two integrated diaphragms (customized sizes
are available upon request). Without compromising the robustness
and reliability for which ICM products are renowned, the small
size and light weight of the SITEX CPSERIES will radically change
the way that you perform your RT inspections. And you will see a
positive impact in terms of both quality and return on investment
