Description
This Pipe line crawler is a highly professional X ray detection equipment which has acquired the national innovation patent, it’s mainly used to detect the welds of Long-distance pipeline. Equipped with digital control and magnetic instructions positioning, features easy operation, compact structure, safety using, accurate positioning, good climbing performance. It was extensively used in the China “West-East gas” project as well as many other abroad pipe line projects and always get good feedback thanks to its topnotch performance.
