A pipe endoscope is also called a poroscope. The main function of the pipeline endoscope is to explore the position where the deep part of the curved pipeline can be observed, but cannot be seen directly. It can observe its internal structure and condition in the sealed cavity, not only to achieve long-distance observation, but also to achieve close operation. In fact, the insistence of endoscopy is to use endoscopy to inspect the inner surface of container, rolling belt, non detachable equipment and narrow gap. Or water and other liquid level and other special, human vision can not directly observe the area of quality inspection and visual inspection method.

国内管道内窥镜是在上个世纪七八十年代的时候从国外引进的,起初它们主要运用于航空,航天等重要领域对产品内部和一些零件进行质量检验。随着国家的发展,科技的不断进步,国内的内窥镜技术也得到了飞速的发展,如今的内窥镜品品种繁多,并且也进入到了实用阶段。管道内窥镜技术也慢慢发展成为了一种比较常规的检测方法。

Domestic pipe endoscopes were introduced from abroad in the 1970s and 1980s. At first, they were mainly used in aviation, aerospace and other important fields to inspect the quality of products and some parts. With the development of the country, the continuous progress of science and technology, domestic endoscopic technology has also been rapid development, today's endoscope products are various, and also entered the practical stage. Pipeline endoscopy technology has gradually developed into a more conventional detection method.

管道内窥镜是根据石油化工、工业机械、电子电气工业、航空航天等直管道内表面的检测要求而设计、生产的新型高科技产品。它是无损检测工具之一，和破坏性检测相比，它的优越性带给我们不一样的感觉。 在汽车领域中，它主要可用于汽车发动机,油箱,制动系统等肉眼无法直接看到的地方，通过它的检测，它可以发现发动机产品内部是否合格或汽车发动机的内部积碳和损坏等问题。
                              

Pipeline endoscope is a new type of high-tech product designed and produced according to the inspection requirements of the inner surface of straight pipeline in petrochemical industry, industrial machinery, electronic and electrical industry, aerospace and other industries. It is one of the nondestructive testing tools. Compared with destructive testing, its advantages bring us a different feeling. In the automotive field, it can be mainly used in the automotive engine, fuel tank, brake system and other places that can not be directly seen by the naked eye. Through its detection, it can find out whether the engine product is qualified or whether the internal carbon deposition and damage of the automotive engine and other problems.

在航空领域中，它主要作用于检查飞机发动机的工作内腔、焊缝表面、导管表面、飞机叶片、涡轮、燃烧室等部件，以及发动机的汽缸、燃料管、油压部件、喷嘴部件等方面;在地下管道领域中，工业内窥镜改变了以往采用的传统人工作业方式，通过它有效的检测，不仅能有效防止工人下井作业遭遇沼气造成安全事故，同时避免了人工目视观察的误差;在铁路行业中，涉及到铁路工程车辆和运输车辆的开发制造，维护检验等不同的领域，甚至在铁路的基建过程，如桥梁和地道的建造，都需要工业内窥镜的检测。

In the aviation field, it is mainly used to inspect the working cavity, weld surface, pipe surface, blade, turbine, combustion chamber and other parts of the aircraft engine, as well as the cylinder, fuel pipe, oil pressure parts, nozzle parts of the engine; In the field of underground pipeline, industrial endoscope has changed the traditional manual operation mode. Through its effective detection, it can not only effectively prevent the workers from encountering the safety accident caused by biogas, but also avoid the error of manual visual observation; In the railway industry, it involves the development, manufacture, maintenance and inspection of railway engineering vehicles and transport vehicles. Even in the process of railway infrastructure construction, such as the construction of bridges and tunnels, industrial endoscope detection is needed.
