Endoscopy is one of the major industrial piping attachment means in the pipeline in petroleum, chemical, pharmaceutical, food and other industrial production device, the endoscope can be observed at any pipeline liquid, gas, steam and other media flow and reactions, play monitor production, the role of the production process to avoid the accident.
Also known as the mirror glass 'as Zhong', its greatest feature is to have the viewing surface 360 ℃ can be seen from all directions to the situation within the pipeline medium; low pressure, generally applicable to the low pressure line

Installation and Maintenance
1, the endoscope is used to observe the liquid flow reaction apparatus, gas, steam and other media, the window glass should be kept clean and free of dust.
2, window glass damaged pieces should belong, to be handled with care when installing the sight glass.
3, glass temperature and pressure have certain limitations, see the instructions on the strict implementation of the provisions.
4, to allow urgent transition temperature (60 ℃, glass breakage due to temperature over the General Assembly.
