[0002] The nondestructive testing type of pressure type special equipment is various. Ultrasonic testing can detect internal defects using ultrasonic reflection principle, and is often used to detect internal conditions of boiler, pressure vessel weld and pipeline. Radiographic testing can clearly present volume defects by means of radiographic penetration imaging, and is suitable for detecting key parts such as pressure vessel cylinder weld. Magnetic powder mainly relies on magnetic powder adsorption by magnetic leakage field to find surface and near-surface cracks, and is widely used in steel pressure parts detection. Penetrant testing is used for non-porous material surface opening defect detection, such as searching for small cracks on the surface of stainless steel pressure vessel, which can effectively ensure the safe operation of pressure type special equipment.

[0003] Magnetic powder detection is an important nondestructive testing method for pressure type special equipment. When detecting, a magnetic field is first applied to the detected workpiece. When the workpiece has defects, its magnetic permeability changes, and a magnetic leakage field is formed at the defect. Then magnetic powder is sprayed or brushed on the surface of the workpiece, and the magnetic powder will be attracted and gathered by the magnetic leakage field to form a magnetic mark, thereby directly showing the position, shape and size of the defect. For example, in the detection of boiler steel parts, surface cracks and other defects can be accurately found to help evaluate the safety of the equipment and ensure the reliable operation of the pressure equipment to prevent accidents.
