In recent years, with the extension of the operation or maintenance cycle of petrochemical equipment, the expansion of production scale and the continuous development of new processes, the complex process environment has increasingly higher requirements for testing products. Endoscope inspection is a kind of inspection technology that has gradually been widely used in recent years with the development of industrial endoscope manufacturing technology. Through industrial endoscope inspection, the staff can check the defect size of pressure vessel and pipeline weld Defect features are accurately judged. Through regular inspection, the staff can find out whether there are new defects in the use process in time, so that the staff can be reminded to repair the equipment in time to achieve the purpose of equipment and personnel safety.

Industrial endoscopes are professionally designed and produced to meet the complex industrial environment. It can be used for inspection and observation of high temperature, toxic, nuclear radiation and places that cannot be directly observed by the human eye. It is mainly used for automobiles, aero engines, pipelines, mechanical parts, etc., and can be used without disassembly or destruction of assembly and equipment shutdown On the other hand, industrial endoscopes can also be connected with cameras, video cameras or electronic computers to form a photographic, video and image processing system to monitor, record, store and analyze visual field targets. Diagnosis and treatment provide a good guarantee.

Industrial videoscope can be used for the detection and inspection of internal defects such as storage tanks, heat exchangers, spherical tank trucks in petroleum refineries, pipeline facilities in the chemical industry, special inspection institutes and pressure vessel production units. At the same time, there is no need to disassemble the inspected equipment during the inspection process, so it is a very cost-effective inspection solution.

Industrial crawler robot  inspection camera technology in the industrial condenser tube, compressor, heat exchanger tube internal inspection, weld inspection, tube wall deposition, pharmaceutical, food stainless steel pipeline corrosion and cracks, overheating inspection and whether there are leaks Inspections, electroplated pipes, and circular weld inspections are widely used. The image processing system and recorder of the video endoscope can effectively record, store and process the inspection defects at any time to ensure the archiving of the image data.

Specific applications are as follows:

Heat exchanger: The heat exchanger is the equipment for heat exchange. It is the necessary equipment to reach the process temperature in the chemical industry, and it is also the most widely used and most important equipment in the chemical industry. The endoscope mainly detects the corrosion of the heat exchange tube of the heat exchanger, and the heat exchange tube with anti-corrosion coating also needs to use the endoscope to check the integrity of the coating during the manufacturing and use process. At present, many domestic chemical companies have many scrapped heat exchangers, some as many as dozens, which are scrapped due to the corrosion of heat exchange tubes. The endoscope can help customers find problems early, thereby helping customers solve unplanned shutdowns.

Heating furnace tube: The pressure reducing device, catalytic reforming device, and hydrocracking device commonly used in the petrochemical industry have heating furnaces. Heating furnaces are widely used in the petrochemical industry and are the top priority of all devices. Coking of the heating furnace tube greatly increases the temperature of the heating furnace tube, thereby increasing the oxidation and corrosion of the furnace tube, which may cause the furnace tube to rupture seriously. Therefore, the endoscope is used to detect the coking condition of the heating furnace tube in the overhaul.

Main pressure pipelines: some pressure main pipelines connected with equipment in the petrochemical industry. This part of the pipeline belongs to the category of high temperature and high pressure. Once corrosion and foreign matter blockage inside, it is easy to cause serious consequences such as pipeline explosion. Therefore, regular video inspection of the main pressure pipeline and treatment of internal problems are vital to the safety of the entire system .

Coking plant heating furnace tube: In the petrochemical industry, there is a coking plant. The medium in the heating furnace tube of this workshop is generally residual oil. The concentration and viscosity of the medium are relatively high, and it is easier to coke in the furnace tube. After mechanical defocusing, an endoscope is needed to detect whether there is coking on the tube wall. The heating furnace tube in the coking plant is more prone to coking than the heating furnace tube in other devices, so more inspection is needed.
