Введение

Измерение зонда сопротивления - это технология обнаружения, основанная на измерении потерь металла. Этот метод определяет скорость коррозии, отслеживая непрерывное изменение значения сопротивления зонда. Это может применяться практически к любой среде и не ограничивается характером процесса. Чувствительный элемент коррозионного зонда ER доступен в различных формах, включая кольцо, трубку, кольцо, плоскую головку и полоску. Датчик изготовлен в основном из 316 нержавеющей стали, а материал может быть настроен на различные среды мониторинга.

История развития

The development of foreign resistance probe corrosion monitoring technology commenced in the 1950s, with the probe acting as a sensitive element exposed to the environment under study. Refinements to the probe structure enhanced the resolution and sensitivity of the probe. Notably, researchers in Europe and the US made significant advancements. By the 1960s, a wealth of patented technologies related to resistance probe corrosion monitoring had emerged in the US, and the technology was clearly defined and ready for industrial application. The 1970s saw the technology mature, with improved sensitivity and accuracy, making it suitable for monitoring environments with low corrosion rates, like atmospheric corrosion. However, due to technological limitations and other factors, measurement accuracy plateaued at the micron level in the 1980s and 1990s.

Принцип мониторинга

The Electric Resistance (ER) Probe technology is a corrosion monitoring technique that measures the resistance change in a metal test piece during corrosion. As corrosion progresses, the thickness of the conductive metal sheet decreases, increasing its resistance. This is because the corrosion products, such as metal oxides, are mostly non-conductive. The initial resistance of the metal test piece is calculated by the formula R=ρl/A, where ρ is the electrical conductivity, R is the resistance, A is the cross-sectional area, and l is the length of the metal test piece. ER Probe technology can be applied in various media, like liquid phase (electrolyte or non-electrolyte), gas, etc. It is simple to operate, easy to maintain, and provides easy data analysis. It also offers real-time corrosion data acquisition and transmission. Due to its high reliability and good economy, it is widely used in industries like oil and gas production, pipelines, the chemical industry, cultural relic preservation, and power generation.

Разработка и применение технологии мониторинга коррозии с помощью электрорезистивных зондов

Corrosion is a costly worldwide problem. The annual economic loss due to corrosion is staggering. In the United States, for example, corrosion costs the economy $276 billion a year, equivalent to 3.1% of GDP. In China, the total annual loss due to corrosion is equivalent to 5% of GDP. In addition, safety accidents caused by the degradation of material properties often have disastrous consequences.

Such accidents often occur when natural gas leaks due to corrosion in a pipeline. The gas then seeps into the main sewer nearby. Serious safety accidents caused by corrosion often occur in our country. For example, in 2013, Sinopec Qingdao Donghuang oil pipeline leak and explosion, mainly due to pipeline corrosion failure.

Metals are the most widely used base materials in industries such as production and construction. In its operating environment, corrosion is inevitable. Therefore, in order to avoid major economic losses and major safety accidents, it is very necessary to monitor the corrosion process of materials under working conditions. Corrosion monitoring is a method to obtain the information of corrosion change, and it is an important part of corrosion technology and corrosion protection.

Технология мониторинга коррозии с помощью зонда сопротивления — это метод обнаружения коррозии, позволяющий измерить изменение сопротивления металла во время коррозии.

ER probe technology is a real-time monitoring tool that provides continuous corrosion data. It has simple principle, convenient operation and wide applicability, and plays a vital role in material corrosion monitoring.

Заключение

Since its introduction in 1970, resistance probe technology has played a crucial role in corrosion monitoring of refining systems in China. Despite great progress and application in various fields such as oil and gas production, transportation, aerospace, environmental protection, cultural relics protection, etc., the domestic development of this technology is still lagging behind. At present, most Chinese companies agent foreign products because of their superior performance, although they cost a lot and sometimes are not well adapted to local conditions. Considering the huge demand in the oil, petrochemical and gas industries, there is an urgent need for China to develop its own efficient and stable resistance probe corrosion monitoring system. This not only has broad market prospects, but also helps to create products with independent intellectual property rights.

Our independently developed resistance probe corrosion monitoring system is a response to this challenge. Our products take into account the domestic industrial and natural environmental conditions and are designed to provide efficient and stable corrosion monitoring solutions, tailored to the characteristics of China. Our probes are known for their high accuracy, long life and affordable price, and have won the favor of many large oil, petrochemical and natural gas companies. More importantly, our products have independent intellectual property rights and are the best choice for domestic substitutes. We sincerely look forward to working with more partners to create a better future and share success.
