[0002] Pipeline filters in the petrochemical industry are used to remove impurities and particles from fluids to ensure smooth process flow. Pipeline filters are small devices that remove solids from liquids. They are mainly used in the transportation of weak acid media such as chemical petroleum. Their working principle is that when the fluid enters the filter cartridge through the main pipe, the solid impurity particles are blocked in the filter cartridge, and the clean fluid is discharged through the filter cartridge and the filter outlet.
