ASME BPE requires endoscopic inspection of pipe welds; however, since the inner diameters of 1/4 and 3/8 inch pipes are too small, the instrument cannot reach inside at bends. Are there any alternative inspection methods?
Detection can be carried out using methods such as ultrasonic testing, X-ray testing, and magnetic particle inspection. Ultrasonic testing can inspect the inner and outer surfaces of pipes, and can detect issues such as corrosion and cracks in the pipes ； X-ray inspection can measure the wall thickness of pipes, as well as detect defects and deformations in the pipe walls ； Magnetic particle testing can detect cracks and defects in welds, joints, and other areas within pipes. Different testing methods are suitable for various pipe materials and pipe sizes, and the choice should be made based on specific circumstances. .
