With the rapid development of industrial automation, robotics and other industries, the development of turbine and plug engine is also accelerating. Cylinder block is one of the most commonly used and important parts. Correct inspection and maintenance before leaving the factory can reduce the failure rate of cylinder block and improve its service life. It is very important for the normal operation of the whole equipment.

With the development trend of rail transit manufacturing industry, the maintenance quality and efficiency of rail transit vehicles and other mechanical equipment are required to be higher and higher. Due to the characteristics of industrial endoscope nondestructive testing technology, it has become an important testing tool in the industrial field.

With the increasing capacity of single unit of thermal power plant and the increasing pressure of boiler, in order to avoid the safety problems and economic losses caused by foreign matter plugging and explosion, the pipeline inspection in installation and operation of thermal power plant has higher requirements.

Clean pipeline is an important part of medical equipment and technology, and it is an important carrier for the transmission of various media in the process of pharmaceutical production. During the construction of pharmaceutical engineering, the slight carelessness of pipeline welding may cause serious consequences.

Industrial endoscope is a new nondestructive testing instrument which integrates optics, precision machinery, electronic machinery, electronic technology and micro camera technology. Traditional non-destructive testing methods can not detect non-point surface defects. Optical fiber is used to transmit illumination light, micro camera and video signal. After processing and amplification, the video signal is sent to the display for imaging.

In the process of factory production, pipeline transmission is essential, so the daily maintenance is also a work that cannot be careless. But most of the pipes are slender, so it is impossible for human eyes to observe it. At this time, the pipe endoscope is needed to enter the pipeline to help the maintenance personnel work.

The pipeline endoscope is a kind of industrial endoscope which can be more inclined to the pipeline of the detection system. Its pipeline length is more suitable for the detection environment of the pipeline.
