Digital Intelligent X-ray Pipeline Crawler HR-90

X-ray pipeline crawler 1.First double-drives pipeline crawler in China. 2.Return automatically if failure arose.

 X-ray Pipeline Crawler

X-ray based weld inspection helps to assure quality in pipeline Construction. The inspection of irregularities in welded seams is indispensable for quality assurance in the production of pipelines, whether for steel or other special alloys. Welded connections in pipes for gas or petrol transportation  must be inspected. X-ray technology has played a significant role in the field of weld inspection.
