An industrial endoscope is a commonly used non-destructive testing instrument. It uses imaging algorithms to realize imaging, photographing, shooting, and operation functions. It is portable, integrated, simple, and easy to operate, significantly reducing users’ work intensity and improving detection efficiency. With direct visualization and photo and video storage functions, it is widely used in energy and power, petrochemical, particular inspection industry, mechanical casting, aerospace, food and medical machinery, and other industries. It is often used to detect parts the human eye, such as pipes, engines, fuel tanks, castings, etc., cannot directly see. Check its inner surface for cracks, corrosion, rust, and welding defects, and check its interior for blockages and foreign objects.

Industrial endoscopes can be divided into mechanical control and electrical control according to the probe-guided control method. The S40 on the production line is an excellent representative of these two industrial endoscopes.

S40 series high-definition industrial videoscope adopts a self-innovated embedded imaging system and mechanical guidance control. Like the electrical products in the embedded imaging system, the probe control system uses automatic manual operation to directly pull the wire rope inside the pipeline to control the steering of the probe, so it is easier to use than electric operation, and the manual process is also required for reset. This series is lighter because there is no core component of electronic control – the steering gear system, and it is easier to replace the pipelines of various specifications. Therefore, the S40 series products can be selected when different pipe diameters need to be tested, can be used for multiple purposes, and are more economical to achieve maximum cost savings.

The million ultra-high-definition industrial endoscope S40 series adopts the self-innovated embedded imaging system and electrical probe control system and realizes imaging, photographing, video recording, and operation functions through imaging algorithms. As one of the main components of the probe control system, the steering gear that controls the response can pull the steel wire in the pipeline in multiple directions to realize the 360-degree steering control of the probe. The electronic control system can automatically reset, adjust the steering speed of the investigation, and adjust step by step. It can be observed in all directions without a dead angle, making the operation more flexible.

The entire transmission mechanism adopts rack and pinion transmission through the research on the zero-delay, no-idle stroke variable speed transmission mechanism. This design ensures a constant instantaneous transmission ratio, high stability, accurate and reliable transmission movement, broad transmission power and speed range, high transmission ratio and transmission efficiency, compact structure, reliable operation, and long service life. The electric industrial endoscope operating system generally has a high definition, accurate steering, fast operation, simple operation, vital portability, and strong integration, significantly reducing the user’s work intensity and improving detection efficiency.

Application case of the industrial endoscope in the detection of appearance defects on the inner surface of storage tanks

Recently, our product application engineer came to a large water heater manufacturer to inspect the internal surface defects of the water storage tank with an industrial endoscope. Industrial videoscopes can be used to perform the following:

1. Inner cavity coating inspection: Check the surface defects of the inner cavity coating, such as cracks, peeling, pull wires, scratches, pits, bumps, pits, corrosion, etc.

2. Weld surface defect inspection: check the inner surface of the weld for cracks, pores, slag inclusions, arc craters, flash, incomplete penetration, and weld leakage.

3. Inspection of internal excess: After removing spatter, scale, pits, paint, and rust on the surface of the weld, observe whether there are residual internal debris, foreign matter, and other excess in the inner cavity of the storage tank for further cleaning.

Scope of application:

SEESEM industrial endoscope has a more precise image and is lighter. The probe can be turned 360 degrees, with accurate steering, flexible operation, and powerful functions, which significantly improves the scope of application of the internal surface inspection of parts. In addition to effectively observing the internal conditions of water storage tanks, industrial videoscopes can also detect welding scars, welds, weld formation, and cleanliness of other types of water storage tanks, containers, and pipes used in various processes. It plays an important role.

The customer compared the SEESEM industrial videoscope with a particular brand and was satisfied with the observation results of SEESEM’s two high-definition industries.

It fully recognized the electric steering control million high-definition industrial videoscope SM50 series, Because it has superior performance in terms of image clarity, screen fluency, and operability. SEESEM industrial videoscopes provide better application solutions for detecting surface defects in storage tanks and bring better product application examples to related industries.

The development of society affects the development of the city. The city’s civilization is inseparable from pipelines, such as drainage pipelines, gas pipelines, drinking water pipelines, and fire-fighting pipelines; so if such a large pipeline group still uses traditional inspections, first of all, the labor cost is enormous. Insufficient timeliness is not ideal for safety; nowadays, the non-destructive testing technology of pipeline endoscopes is becoming more and more advanced, and the cost is getting lower and lower. With the popularity of industrial endoscopes, people do not need to inspect and repair pipelines destructively. There are various operation and inspection methods, and the industrial endoscope’s visual inspection method is one of them. This pipeline detector can be applied to detect welds, corrosion, and various sundries inside the pipeline and is widely used.

In the particular inspection industry, for the detection and inspection of pressure pipelines, the macroscopic assessment is carried out by visual inspection and prevention in the early stage. Users can use visual inspection tools such as industrial endoscopes to inspect the internal structure, geometric dimensions, and surface conditions (such as cracks, corrosion, leakage, deformation, etc.).

The pipeline structure and geometric dimensions should be inspected during the first periodic inspection. During the second regular inspection, only the pipelines that have suffered from fatigue, the channels that have undergone transformation or significant repairs, and the focus on the review of whether there are new defects in the abnormal parts of the structure and geometric dimensions.

Visual inspection shall generally include the following:

1) Inspect pipeline structure, including pipeline layout, support, hanger, expansion joint, opening reinforcement, discharge device setting, etc.

2) Geometric dimension inspection, including misalignment, undercut, weld reinforcement, etc.

3) Appearance inspection, including corrosion, cracks, leakage, bulging, deformation, mechanical contact damage, overheating, arc burns, deformation and cracking of pipe support parts, pipe support parts deformation, cracking, and discharge (drainage, sewage) devices Blockage, corrosion, deposits, damage, and peeling of the anti-corrosion layer, damage and peeling of the insulation layer, decay and cracks in the supermarket and under the insulation layer, etc.

(The above part is excerpted from the “Periodic Inspection Rules for Pressure Pipelines-Industrial Pipelines” TSG Special Equipment Safety Technical Specifications.)

As a commonly used visual inspection tool, industrial endoscopes can directly observe defects on the surface in inspecting industrial pipelines, boilers, and other special equipment. They can save data by taking pictures and videos, which is more convenient to use, easy to operate, light, and easy to carry, so it has been widely used.

Seesem industrial endoscope has been focusing on the industrial endoscope for five years. It has independently developed and produced various industrial endoscope products. Its original pipeline replaceable system can alone replace various specifications of pipelines with different diameters, lengths, and depths of field. , waterproof, oil-resistant, and anti-corrosion. Millions of high-definition cameras have better image quality with automatic white balance image processing technology. The mechanical/electrical control joystick controls the probe to turn 360° to realize observation without a dead angle. At the same time, the whole machine is more compact and easy to carry, and the operation is more convenient and worry-free.

The endoscopic pipeline inspection is also called QV inspection, a method of detecting the inside of the pipeline using endoscopic technology. Using this detection method can not only solve the problem that the camera distance cannot meet the length of the channel and the upload rate is too slow to be synchronized but also can accurately determine the material defects, corrosion degree, and specific location of the pipeline, and the detection results can be used as the basis for evaluating the health of the channel.

• The principle of pipeline endoscopy detection technology

Use video to monitor and shoot the internal deposition of the pipeline, pipeline damage, foreign matter penetration, leakage, branch pipe concealed connection, etc., and can see and record all the conditions inside the channel from a long distance. Then the video is transmitted to the ground and stored in the host computer. Professionals analyze all the video data one by one, systematically and comprehensively understand the basic situation of the pipeline, understand its drainage quality and operation, as well as the location of the water outlet and the degree of damage to the channel, write a pipeline inspection report, and provide for the track. Maintenance and Restoration offer an economical and efficient detection method.

The QV detection system comprises the central controller, the portable pole with the camera installed, and the cable to connect the central controller and the mobile bar. The main controller can be tied to the operator’s chest with a strap, and the operator can adjust the free rotation of the camera, lens stretching, shooting, and observation by changing the central controller and saving the original video data in the main controller. For further analysis.

• Pipeline endoscopy inspection technology working procedures

The QV technical work program testing work program includes: collecting existing pipeline information, work plan design, on-site exploration, internal industry data analysis, and writing reports. According to the actual situation, adjustments can be made. In some cases, such as when the well is full of water, it is necessary to adjust the valve to lower the water level to less than half of the nozzle to advance the QV.

• Video Analysis Method of Pipeline Endoscope Inspection Technology

The critical work of QV technology is to interpret and analyze the video data to see whether there are defects in the pipeline, the type, level, and several flaws.

The emergence of pipeline endoscopic detection technology provides a simple, intuitive, and effective detection method for the status quo of the urban pipeline network system, ensuring the stable operation and development of the city. Pipeline endoscopic inspection technology plays a huge role in urban pipe network inspection and has apparent application effects in other fields such as electric power, petrochemical, aerospace, and other areas.

• How does an industrial pipeline endoscope solve the problem of pipeline bends?

Pipeline, everyone must be familiar with it. Pipes of different materials and shapes are used in all aspects of industrial production and serve thousands of households. The pipeline may seem ordinary, but it has a vital role! Is there any foreign matter inside the pipe? Are the pipe-to-pipe connections secure? Are the pipes corroded? These problems are widespread. So how can we quickly find the answer and plan for the next step? Let’s talk about it today!

How to survey the situation inside the pipeline has always been a headache. Are there foreign objects inside? Is the internal welding secure? These questions, industrial endoscopes, can quickly give answers! The inner wall of the pipeline is easy to produce scale and other foreign matter. Once the foreign value is generated, it will not only affect the regular use of the channel, but in severe cases, it may cause an explosion.

Let’s examine how the industrial endoscope picks up internal foreign matter. The pipeline’s internal Corrosion and the weld seam also need attention.

Now industrial endoscopes can see not only foreign objects clearly but also measure various values of foreign objects! Sections of pipe elbows have always been difficult to inspect.

Using endoscopy inspection solutions:

1. Quick, easy, and complete coverage

2. Covering an extensive range of pipe diameters

3. Cover the elbow surface

4. Fast, easy, and complete coverage

5. Reduce duplication of labor and inspection time

6. Larger sound beam coverage width can ensure fast detection

Corrosion in pipelines is complex. Not only to find them in time but also to analyze them properly, which caused the decline. Metal corrosion can be quickly investigated on-site through industrial endoscopes, and corrosion composition information can be obtained promptly, which helps to understand Corrosion and find solutions to prevent decay. It has broad application prospects in refineries, petroleum and petrochemical industries, power plants, and shipbuilding industries.

Car owners who like German cars must be car owners with specific cultivation and knowledge and are willing to learn about some car maintenance issues. Some time ago, some drivers exchanged opinions, reflecting that there are many corrosion spots on the cover of the BMW 3 Series engine and generator, and asked whether it would affect safety. My answer is no!

Since the organic matter required for mold growth is absent on the engine and generator surfaces, it can be concluded that these spots are not mold. These parts are made of aluminum alloy die casting. After curing, an oxide film should form on the surface. This aluminum oxide film can prevent further oxidation of the internal aluminum and play a protective role. However, the microstructure of aluminum alloy dies castings is loose, containing various metal or non-metal inclusions, and voids are prone to appear on the surface. Suppose the oxide film is not dense, for example. In that case, there is a gap in the middle of the film, or the compound of other elements causes a crack, or foreign chemical substances damage the film. The corrosive gas or medium can easily invade the gap and cause corrosion. After corrosion, aluminum oxides exist in the form of powder and fibers. In addition, the color of oxides of elements such as copper in the aluminum alloy seems to contrast with the surrounding background color, like mold. It’s not mold; it’s surface oxidation. Therefore, the essence of the spot should be the oxidation corrosion on the surface of the die-casting aluminum alloy. Our naked eyes cannot observe the above situations; we can only rely on the car endoscope to complete them.

How do I check my vehicle engine? This is a problem that many car owners are troubled by. First, we review the entire space in the order of the machine, generator, oil circuit, oil circuit, and control sensing circuit. Periscope and endoscopy can be used if available. These can be found in the Baidu search endoscope factory, and they are not too expensive to buy. Then open the upper cover of the engine and check the connecting parts and metal body. The external corrosion of these aluminum alloy parts has little effect on the vehicle’s performance. This phenomenon can be significantly delayed as long as they are checked and wiped frequently.
Avoid spilling or splashing when adding oil and liquid at ordinary times. Because it prevents fat from dripping on the metal body, if it leaks, wipe it off in time. In rainy, snowy, and freezing weather, the body should be cleaned and wiped, and the engine compartment should be brushed and dried after using the car. At present, the air quality is not good, acid rain and suspended particles are inevitable, and sulfur and dust accelerate the corrosion of aluminum alloy under certain conditions. In freezing weather, snowmelt will be sprinkled on the road. This industrial salt is corrosive. Pay attention to cleaning the body and chassis after driving. After all, washing is healthier.

As well-educated car owners, we must master the endoscope to perform daily inspections of the engine compartment.
