Steel Pipe X Ray Inspection Equipment

Steel pipe X ray inspection equipment is mainly used to detect whether there are defects (cracks, blisters, pores, white spots, inclusions, etc.) inside the steel pipe, whether the welds are qualified, and whether there are any dark injuries, so as to judge whether the steel pipes are qualified or not.

Description

Steel pipe X ray inspection equipment

Steel pipe X ray inspection equipment is mainly used to detect whether there are defects (cracks, blisters, pores, white spots, inclusions, etc.) inside the steel pipe, whether the welds are qualified, and whether there are any dark injuries, so as to judge whether the steel pipes are qualified or not. X-rays can penetrate metal materials, and because the materials absorb and scatter differently, so that the film is not sensitive to light, so images with different blackness are formed on the film, and the internal defects of the materials are judged accordingly.
