Discussion on corrosion detection and pipeline protection technology of oil and gas pipelines

For oil and gas pipelines, the corrosion problem is more common. For the corrosion detection and pipeline protection of pipelines, combined with the development status of related technologies at home and abroad, the importance of the quality of oil and gas pipelines is systematically analyzed, and the current common oil and gas pipelines are corroded. The detection technology is discussed and compared,and common pipeline protection technologies are discussed to lay the foundation for the further development of oil and gas pipeline corrosion detection and pipeline protection technology. Research shows that since the quality of pipelines is directly related to the operational safety of pipelines, it is very important to improve the quality of oil and gas pipelines as much as possible. The common corrosion detection techniques are frequency conversion frequency selection method, human body capacitance method and PCM method, among which PCM method more advanced; common pipeline protection technologies include corrosion inhibitor anti-corrosion technology, pipe coating technology, ordinary carbon steel technology, corrosion-resistant alloy tube technology and FRP or plastic pipe technology. In order to ensure pipeline safety,relevant technologies can be selected to reduce pipeline corrosion rate.
