Applied Study on Filtering for Lanzhou-Chengdu-Chongqing Products Oil Pipeline

The study background, study content and application achievement of new filtering technique for Lanzhou-Chengdu-Chongqing Products Oil Pipeline are described in this paper. The old vertical filter for products oil filtering is difficult to collect impurities and be cleaned. Therefore, a special filter with quick-opening blind plate of pig trap is developed. This new filter can be operated without any craning equipment.
