I. Overview

Electromagnetic ultrasonic corrosion thickness gauge is an advanced non-destructive testing equipment that combines electromagnetic induction principle with ultrasonic technology. Its working principle is based on the electromagnetic ultrasonic effect, which sends ultrasonic signals to the measured object through electromagnetic sensors, and determines the wall thickness and corrosion condition of the equipment through the reflected signals. Compared with traditional corrosion detection methods, electromagnetic ultrasonic thickness gauges have advantages such as non-contact measurement, no need for physical contact surfaces, and strong adaptability.

2、 Core advantages

1. Non contact detection

One of its advantages is its non-contact nature. In many special industrial environments, equipment surfaces may be covered with anti-corrosion coatings, dirt, grease, etc., which often affect traditional measurement methods. It can directly penetrate these material layers through the combination of electromagnetic induction and ultrasonic waves, accurately measuring the true wall thickness of the equipment.

2. High precision measurement

Capable of providing highly accurate corrosion detection results, with errors typically in the micrometer range. Even under complex working conditions, the reliability of the detection results can be ensured. This is particularly important for industrial equipment that requires long-term operation and significant changes in pressure and temperature.

3. Real time and convenience

It has the function of real-time data collection and display, allowing operators to obtain real-time feedback on the degree of corrosion and equipment status, and take corresponding maintenance or anti-corrosion measures in a timely manner. In addition, the device is small in size and easy to operate, allowing for rapid on-site testing, saving a lot of time and cost.

4. Strong adaptability

Not only suitable for measuring corrosion on metal surfaces, but also capable of stable operation in harsh environments such as high temperature, high pressure, humidity, etc. This makes it widely used in various industries such as petroleum, chemical, power, shipbuilding, aviation, etc.

3、 Application of Electromagnetic Ultrasonic Corrosion Thickness Gauge in Industrial Corrosion Prevention

1. Oil and gas industry

Oil and gas pipelines often face corrosion threats from the external environment during transportation. Especially after prolonged use, the wall thickness of the pipeline may gradually become thinner, posing a risk of leakage. By using instruments, it is possible to conduct regular inspections of pipelines without disassembling the equipment, detect potential corrosion hazards in advance, and avoid accidents caused by corrosion.

2. Chemical industry

In chemical plants, equipment is exposed to highly corrosive chemical media all year round, resulting in severe corrosion. It can help enterprises detect corrosion risks in a timely manner, prevent accidents, and ensure production continuity by accurately measuring the wall thickness of equipment such as reaction towers, heat exchangers, and pipelines.

3. Power industry

Heat exchange equipment, boilers, and pressure vessels in the power industry typically require prolonged exposure to high temperature and pressure environments, making corrosion particularly complex. It can effectively monitor the corrosion status of equipment, ensure that the equipment operates under safe working conditions, and reduce sudden failures.

4. Shipbuilding industry

Ships sailing in the ocean face harsh environments such as saltwater and wind waves, and their hulls often suffer from seawater corrosion. It can regularly check the thickness of the hull, detect potential corrosion problems early, extend the service life of the ship, and ensure navigation safety.
