The corrosion detection technology and anti-corrosion of oil and gas pipelines

Oil and gas pipelines are subject to various forms of corrosion during use. Such as oxygen corrosion, hydrogen sulfide corrosion and soil corrosion. This will affect the service quality and service life. At the same time, it also brings great security risks. Therefore, the following is mainly based on the corrosion mechanism. We discuss the corresponding corrosion detection technology and reasonable anti-corrosion measures.

An important problem in the use of oil and gas pipelines is the anti-corrosion of pipelines. Many experts at home and abroad are committed to the anti-corrosion research of oil and gas pipelines. The anti-corrosion detection technology and anti-corrosion measures are also gradually developed and improved with the deepening of research.

Firstly, the Type and mechanism of oil and gas pipeline corrosion

Because oil and gas pipeline construction requires high technology. And it takes a long time. So it can be seen from the statistical data after the operation of domestic oil and gas pipelines. Corrosion perforation usually occurs after one year. Which affects oil and gas transportation. And the leakage of oil and gas will bring great safety risks. Oil and gas pipeline corrosion is the reaction of pipeline material after contact with air. From the perspective of corrosion mechanism, it mainly includes oxygen corrosion, hydrogen sulfide corrosion, and soil corrosion.

oil and gas pipeline

The pipe material is usually iron. It will produce rust under the joint action of oil, gas, water molecules and oxygen. The corrosion rate will accelerate with time. Hydrogen sulfide has high flammability and acidity. So it is easily dissolved in water to form an aqueous solution of hydrogen sulfide. The pipeline will be severely corroded in this weak acid environment. Buried oil and gas pipelines will be affected by such factors as soil stray current, water content, pH and humidity. The two lead to pipeline corrosion due to potential difference.

To reduce pipeline corrosion. First of all, in the process of producing pipelines, the basic factor affecting the service life of pipelines is the quality of pipelines. Unqualified products are more prone to cracking and corrosion of internal and external walls during use. Secondly, the material of the pipe. Steel pipes have a high non-metallic content. It is easier to produce chemical reaction with oil and gas and surrounding environment after buried construction. This led to corrosion cracking of the pipeline. The third is the impact of the natural environment. The temperature, moisture and soil of the environment where the pipeline is located will have an impact. This may lead to problems in the use of the pipeline if the impact of environmental factors cannot be properly handled during the construction process.

Secondly, Corrosion detection technology of oil and gas pipelines

The corrosion detection technology of oil and gas pipelines mainly includes CCTV camera technology.And also magnetic flux leakage detection technology, ultrasonic detection technology, and other related technologies.

2.1 CCTV camera technology

The corrosion of oil and gas pipelines will damage their normal performance. This requires the adoption of scientific detection technology. It can dynamically understand the corrosion situation and corrosion location. Therefore, the application of CCTV camera technology can carry out dynamic whole process detection on the inner wall of the pipeline. This technology mainly uses a camera to image the aperture in the pipeline. The imaging data is saved to the computer. Technicians identify defects by quantitatively analyzing these images. In this way, dynamic monitoring can be realized. It also improves the accuracy and speed of corrosion detection. This also provides a basis for automatic detection.

2.2 Magnetic flux leakage detection technology

Because this technology has a long history of application in pipeline inspection. So it is easy to grasp and easy to use. Oil and gas have different corrosion rates to steel pipes and bars. This technology uses this distinction for detection. A magnetic flux leakage detector is composed of a processing instrument, sensor, and battery. Whether there are defects in the steel pipe will have different permeability. The difference between different sections of the pipeline will be reflected the computer through the sensor. Technicians can take this as a basis. After that, the corrosion condition and corrosion position can be judged.

2.3 Ultrasonic testing technology

Because the corrosion degree and position of the inner wall of the pipeline are different. Therefore, there will be a certain acoustic time difference when ultrasonic testing is adopted. At this time, the ultrasonic wave will be collected and received by the probe. So we can judge the corrosion by analyzing and studying these data. Ultrasonic testing technology also has many advantages. Such as simple detection data and high measurement accuracy. And it no longer requires subsequent measurement and inspection. This technology has high requirements for equipment. Under the current development situation. It is usually only used for large-diameter and thick wall pipe inspection. The propagation process needs a certain medium. This limits the reliability and scope of its application and needs to be improved. In addition, the ultrasonic detection technology should be carried out without cracks in the pipeline. Otherwise, the accuracy of the detection data cannot be guaranteed.

In addition to the above three detection techniques. There are eddy current detection technology, human capacitance method, and frequency conversion and frequency selection technology. From the advantages and disadvantages of these technologies, each has its own advantages. But they also have their own adaptive environments. For example, the human body capacitance method has a limited transmission distance. And it also needs higher-quality inspectors to operate. The frequency conversion detection technology cannot be applied to long-distance detection. The advantage of this kind of detection is that it has fast detection speed and convenient operation in the process of field application.

Thirdly, Anti-corrosion measures for oil and gas pipelines

The anti-corrosion measures for oil and gas pipelines can mainly be taken from ensuring the pipeline material and applying anti-corrosion coating technology, and electrochemical anti-corrosion technology.

3.1 Application of anti-corrosion coating technology

Firstly, this is the most widely used anti-corrosion measure, and the types of anti-corrosion coatings are gradually developed with the development of technology. Secondly, inorganic non-metallic corrosion protection shall be adopted. Because this method was first applied abroad. Which improves the organic coating process. It circumvents its disadvantages. Therefore, enamel coating, glass coating, and ceramic coating are applied in pipeline anticorrosion. Its advantages are also good wear resistance, high-temperature resistance, and oxidation resistance. Thirdly, nanomaterials are used. The application of nanomaterials can also greatly improve pipeline toughness. So it improves the anti-corrosion and waterproof ability of the pipeline.

3.2 Application of electrochemical corrosion

In buried pipelines. The current in the soil will lead to pipeline corrosion. So this is an important cause of pipeline corrosion. And then electrochemical corrosion protection is to adjust the corrosion potential of metal through current. This can reduce the corrosion of metal pipes. At last, it mainly protects the damaged parts through the metal layer with negative thermal potential on the surface of the metal pipe.

At last, Concluding remarks

So Anticorrosion of oil and gas pipelines has always been a problem to be faced in pipeline construction. Through the public efforts of relevant researchers and practitioners, anticorrosion detection technology has also made great progress. But there is still serious corrosion in domestic pipeline applications. New materials and technologies shall be also applied in the anti-corrosion of pipelines to improve the service quality and service life of pipelines.
