摘要
Abstract
In order to improve the performance of the anti-corrosion coatings of long distance pipeline and meet the practical needs of pipeline engineering,the development status of the anti-corrosion technology of China's long distance oil and gas pipeline was analyzed,the advantages and disadvantages of various anti-corrosion coating properties were summarized,and the application of anti-corrosion technology of long distance pipeline was combined.The reasons for the high cost,high requirements of coating technology,difficulty of patching and easy mechanical damage of 3PE anti-corrosion coating and heat-bending pipe anti-corrosion coating,which are widely used at present,are analyzed,and the research direction of external anti-corrosion technology of long-haul pipeline is put forward.关键词
