随着科学技术的不断进步,我国天然气输气工程有了很大发展,但管道在长期的运行工作中,还是会产生一定的水、硫分、粉尘、机械杂质等物质,久而久之,这些杂质粘贴在天然气输送管道内壁上,如果得不到及时有效的清理,就会严重影响天然气运送过程中的质量和效率,不利于天然气输送管道的正常运行。本文将对天然气输气管道的清管工艺作一分析,对常见问题进行探讨,并提出有效改良方案。
With the continuous progress of science and technology, China’s natural gas transmission project has made great progress, but the pipeline in the long-term operation, or will produce some water, sulfur, dust, mechanical impurities and other substances, over time, the paste of these impurities If the inner wall of the natural gas pipeline is not cleaned up in time, it will seriously affect the quality and efficiency of natural gas transportation and will not be conducive to the normal operation of the natural gas pipeline. This article will make an analysis on the pigging technology of natural gas pipeline, discuss the common problems and propose effective improvement schemes.
