Pressure piping in boiler pressure vessel and special equipment inspection, because of the complexity of the test object, thus have a high request for detection tools. Along with the development of the nondestructive tool continuously, nondestructive tool in which play an important role, including industrial endoscope in pressure pipeline and industrial boiler pressure vessel has played an important role.
Industrial endoscope can be used in high temperature, toxic, radiation and the site of the human eye cannot directly observe the inspection and observation, is mainly used in automobile, aviation engine, pipes, machinery parts, etc., can be in do not need to remove or destroy assembly and realize nondestructive testing equipment to stop running circumstances. Industrial endoscope in pipeline detection plays an important role. Through the detection of industrial endoscope, the staff of the pressure vessel and pipe welding seam defect size and defect characteristics of accurate judgment.
