24/7 SCAR Radiography Inspections
Increase Turnaround and Outage Productivity
Maximize SCAR Radiography Performance With Se-75
Minimize Exclusion Zones
With the SENTINEL 1075 SCARPro, you can obtain up to 98% reduction in exclusion zones compared to conventional radiography techniques.
Utilizing FlexShield radiation blankets, guide tube shields, and scatter shields with proper technique, you can achieve exclusion zones as small as 3 to 6 feet (1 to 2 meters) for demanding applications or 10 to 15 feet (3 to 5 meters) for typical applications required by clients to realize the SCAR value.
QSA Global, Inc.’s sales team and local distributors provide custom-tailored solutions to help your clients maximize turnaround efficiency, eliminate interference from radiographic testing on nucleonic process control gauges, and meet exclusion zone requirements.
SCAR Production: Turnarounds & Outages
During turnarounds and outages, traditional gamma radiography is either performed in shooting windows totaling only 1-2 hours in a 12-hour shift or other trades such as welders and electricians must be cleared from the exclusion zone while radiography is performed.
The SCAR Radiography technique utilizing the SENTINEL 1075 SCARPro eliminates the need for shooting windows or impacting other trades. The SENTINEL 1075 SCARPro enables continuous 24/7 gamma radiography inspections maximizing inspection productivity and accelerating your turnaround.
Nucleonic Gauges & Safety Systems
These systems often cannot differentiate the radiation they are designed to detect from radiation resulting from radiographic testing. As a result, critical processes may need to be manually monitored, operated without real-time process information, or shut down entirely while traditional radiographic testing (RT) is being performed.
The SCAR radiography technique allows you to perform RT in close proximity to these sensor systems without risking interfering with process measurements or generating false alarms in critical safety systems.
Switch Configurations Effortlessly
The SENTINEL 1075 SCARPro allows you to realize the value of SCAR radiography for virtually any type of shot. The system comes standard with a contact fixture kit to perform contact SCAR. An optional offset kit is available for superimposed or elliptical shots on small diameter pipes or profile radiography.
Contact Fixture Configuration
The SENTINEL 1075 SCARPro comes standard with a contact fixture kit to perform category I close-contact SCAR radiography. The contact fixture kit allows you to securely mount the exposure device to any diameter pipe. Contact shots are typically preferred on piping 3″ OD and above.
Contact Fixture Configuration
An optional offset fixture kit is available when you require an increased source to film distance (SFD) for small piping, typically 2″ and below. The offset fixture kit allows you to achieve the necessary SFD to perform superimposed and elliptical shots. The offset fixture kit securely mounts the source projector in any orientation. If the pipe itself is not suitable for mounting due to insulation, thin wall, access, or other issues, the offset fixture kit can easily be attached to other nearby piping or even structural material and the components can be configured to aim the SENTINEL 1075 SCARPro’s collimated beam at the sample.
