The tube endoscope is also known as Kong Tanyi." style="box-sizing: border-box;background: transparent">Periscope for pipeline inspection The main function is to detect the depth of the bent pipe and so on, but not to look directly at the location. It can observe the internal structure and condition in the sealed cavity, not only to achieve long-distance observation, but also to achieve close range operation. Endoscopy is actually the use of endoscopes for containers, roll belts, inside and outside surfaces of small and narrow gaps. Or water and other liquid level and other special, human vision can not directly observe the area for quality inspection and visual inspection methods.   

Domestic pipe endoscopes were introduced from abroad in the 70s and 80s of last century. At the very beginning, they were mainly used for quality inspection of internal parts and parts in aviation, aerospace and other important fields. With the development of the country and the continuous progress of science and technology, the technology of endoscopy in China has been developing rapidly. Nowadays, there are a wide variety of endoscopes and have entered the practical stage. The technology of pipeline endoscopy has gradually developed into a more conventional detection method.   

Pipe inspection periscope is a new high-tech product designed and manufactured according to the requirements of internal surface inspection of petrochemical, industrial machinery, electronic and electrical industry, aerospace and other straight pipes. It is one of the nondestructive testing tools. Compared with destructive testing, its superiority gives us different feeling. In the field of automobile, it can be used mainly in automobile engine, fuel tank, brake system and other naked eyes which can not be seen directly. Through its detection, it can find out whether the internal product of the engine is qualified or the internal carbon deposition and damage of the automobile engine.   

In the field of aviation, it is mainly used to inspect the internal cavity, weld surface, pipe surface, aircraft blade, turbine, combustor and other components of the aircraft engine, as well as the cylinder, fuel tube, oil pressure parts and nozzle components of the engine. In the field of underground pipelines, the industrial endoscope has changed the traditional manual operation mode adopted in the past, and has been effectively detected through it. Not only can it effectively prevent workers from encountering methane accidents caused by downhole operation, but also avoid the error of manual visual observation. In the railway industry, it involves different fields such as the development, manufacture, maintenance and inspection of railway engineering vehicles and transport vehicles, and even in the process of railway infrastructure construction, such as bridge and tunnel construction, it needs the detection of industrial endoscopy.
