Performing radiographic examination using crawlers could speed up the inspection work up to four folds. OAG crawlers can be used to carry X-Ray tubes, Se-75 or Ir-192 sources for pipelines with sizes from 6 inches to 72 inches diameter.

OAG has been at the forefront of the development of the crawler technology with major projects in the past eight years under our belt. Our crawlers have been seen in action at extreme conditions from the winter of Eastern Europe to the deserts of the Middle East.

Using the crawler-carried source, only one shot is required for each weld, regardless of the pipe size. A major plus point is that the technicians do not have to physically carry the sources anymore, which reduces fatigue on the operators. Each radiography team has at least one experienced crawler technician.
