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 in use must be inspected regularly. X-ray technology has played a significant role in the field of weld inspection.
