Description

Technical Field

[0002] Non-destructive testing is a technology that uses principles and techniques such as rays, ultrasound, infrared, and electromagnetism and combines instruments to detect defects, chemical, and physical parameters of materials, parts, and equipment without damaging or affecting the service performance of the tested object. After the steel is produced, the inspection of steel structure projects includes all the specified test and inspection contents of raw materials, welding materials, welded parts, fasteners, welds, bolt sphere joints, coatings, etc. of steel structures and special equipment.

Thus, when detecting the steel pipe, there is no need to hold the device manually, and at the same time, it can ensure that the distance between the flaw detector 209 and the inner wall of the steel pipe is the same during detection. Therefore, the detection accuracy of the detection device can be improved.
