X-ray Pipeline Crawler:
It is an automatic specialist equipment of pipeline weld inspection for petroleum and natural gas industries. It is especially fit for inspection of long pipelines with such features as high radiographic quality, great imaging sensitivity, low failure rate and high working efficiency. It has differential driving and vibration absorbers, and its chassis can be moved inside the pipeline without off tracking and overturning. Great efficiency can thus be achieved through the PLC control system in the detector, which would protect it from blocking and under voltage.
