What equipment can be used for nondestructive testing（NDT）?
The answer is industrial endoscope/borescope/videoscope/ endoscopio/endoscopia/inspection camara
Endoscope is a general tool for many disciplines. Its function is to explore the depth of curved pipes, observe the parts that cannot be seen directly, observe the internal space structure and state in the sealed cavity, and realize long-distance observation and operation. Endoscopic inspection is a visual inspection method that uses industrial endoscopes to control the quality of containers, pipelines, the interior of non removable equipment, the inner surface of narrow gaps, water, oil and other parts below the liquid level and areas that cannot be directly observed by human vision in special environments.
Principle of nondestructive testing(NDT) of industrial endoscope/videoscope/borescope/inspection camara
Industrial endoscope is a branch of nondestructive testing(NDT), which can also be said to be a special testing technology.
Nondestructive testing requires the use of industrial endoscopes as testing tools, which are professionally designed and produced to meet the complex industrial environment. Endoscope detection is a kind of detection technology that has been widely used in recent years with the development of endoscope manufacturing technology. According to the characteristics of manufacturing process, we generally divide industrial endoscopes into three types: optical rigid tube endoscopes, fiber optic endoscopes, and video endoscopes.
Industrial endoscope can be used for inspection and observation of places that are high temperature, toxic, nuclear radiation and cannot be directly observed by human eyes. It is mainly used for automobiles, aeroengines, pipelines, mechanical parts, etc. it can realize nondestructive testing without disassembling or destroying the assembly and stopping the operation of the equipment. On the other hand, industrial endoscope can also be connected with cameras, cameras or electronic computers to form photography, camera and image processing systems, So as to monitor, record, store and analyze the image of the field of view target It provides a good guarantee for diagnosis and treatment.

Application of industrial endoscope
Electronic endoscope is a new high-tech product designed and produced according to the inspection requirements of the inner surface of straight pipelines such as petrochemical industry, industrial machinery, electronic and electrical industry, aerospace and so on. It integrates optical, mechanical, electrical and image processing software. The industrial endoscope is equipped with a high-resolution color monitor or a pen computer with USB port. The computer is more convenient to carry, and the observation image is clearer, so that the operator can use high-resolution color CCD, With the help of the unique professional software processing system, the observed doubtful points and flaw detection parts can be frozen, amplified, analyzed, measured and printed, which greatly improves the accuracy of judging the flaw detection parts of the inner wall of the pipeline.
It is convenient and reliable to use. For example, the inspection and maintenance of defect detection and condition monitoring of important equipment such as turbines, pipelines, condenser tubes, pumps, boilers, heat exchangers, valves, pressure vessels, etc. are needed, and the equipment detection of nuclear power plants, wind power plants, hydropower plants, thermal power plants and power construction units is even more indispensable.
Turbine cleaning, blade and nozzle / nozzle blockage inspection, recovery of fallen parts, internal and external corrosion of pipelines, main steam pipelines, water supply heaters, condensers, wind turbines, blade operation status, refining / oil transmission lines and sealing systems, valve base inspection, turbine / generator / generator, generator stator inspection, blade inspection.
Public security and customs
Weapon manufacturing is used to check the wear, looseness, oil leakage of mechanical gear parts and the internal condition of gun barrel. Security inspection is used by public security and customs departments to inspect drugs and smuggled goods. Video endoscope technology has also been applied in weapon manufacturing, daily maintenance, security, customs inspection, search and rescue, and life detection. Search and rescue detection is used for earthquake search and rescue, emergency search and explosion-proof inspection.
Mechanical casting industry
It is used in automobile parts casting, hydraulic casting, pump body and valve body casting, mechanical parts casting, pipeline and pipe fittings casting units, and is used to check the quality control of casting sand inclusion, burr and staggered holes.
Routine maintenance and inspection of large diesel engines, various engines and pipelines in railways and ships. It is used for regular inspection of aircraft turbine, blade, engine, weld surface, duct surface, combustion chamber interior or body inspection, as well as research, development and manufacturing of rocket engine.
There is no need to disassemble the tested equipment in the testing process, so it is a very cost-effective testing solution. Especially in 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 stations and pressure vessel production units.
Automobile manufacturing, means of transportation
Endoscope is also an indispensable daily tool in the cleaning and maintenance of automobile engine. At the same time, it is simple, flexible, compact and easy to carry. The soft, small and flexible insertion tube can reach any hidden part that needs to be checked. Automobile endoscope is widely used in automobile production and maintenance industry. It is mainly used to detect and diagnose the wear, carbon deposition and blockage of automobile engine, cylinder, oil pressure parts, fuel pipe, engine, muffler, transmission and air conditioning system, differential, water tank, oil tank, gearbox, etc., which improves work efficiency, reduces repair costs, and avoids the damage caused by repeated disassembly and assembly of parts.
Locomotive, engineering, pharmaceutical, food pipeline
In railway / ship,inspection camara is used to inspect electric locomotive, air conditioning system, turbine, heater, diesel engine, boiler flame and pipeline. Construction engineering is used to check the corrosion and dirt of steel pipes, internal diagnosis of walls, rust of reinforcement, cracks of support shafts and bridge joints, etc. it can also be used to observe the cavities inside the tunnel and building models; Diagnosis of corrosion and blockage of tap water drainage pipe. Research institutions are used for observation, scientific research, laboratories, archaeology, etc. of research institutions.
Development trend of industrial endoscope
Industrial endoscope technology has unique advantages. It can extend people's sight distance, change the direction of sight at will, and accurately observe the real condition of the inner surface of the object, which cannot be replaced by other detection instruments. For example, in the application of aviation, the industrial camera/videoscope can be extended into the interior of the aircraft engine to directly observe the real internal condition or the internal surface condition of equipment parts after operation; Effectively detect the surface condition of concealed or narrow parts without disassembling the equipment or components for destructive inspection. The method is simple, reliable, intuitive and effective. Whether in the field of aviation, aerospace, electronic industry and other manufacturing In the maintenance industry, the use of endoscope for NDT detection has achieved good results, solved many difficult problems, ensured the normal operation of the whole set of equipment, and avoided some accidents.
Now the application of industrial endoscope technology has developed to the use of computer image processing technology, printing technology and network technology to complete the capture, storage, processing and analysis of images under endoscope, the writing of standardized reports, advanced document management, accurate image measurement and analysis, local enlargement, clear graphic and integrated report output, etc.
