Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a high-efficiency petrochemical pipeline filter. Background Art

[0002] In the petrochemical industry, the pipeline system is a key component for transporting petroleum and chemical products. Since crude oil and other petrochemical products contain impurities, particulate matter and sediment, these substances may cause corrosion, blockage and wear to the pipeline, affecting production efficiency and product quality. Therefore, it is necessary to set up a pipeline filter in the pipeline system to filter these harmful substances to ensure the continuity and safety of petrochemical production; however, the top of the conventional petrochemical pipeline filter is sealed by a sealing flange, and the sealing flange is usually fixed with bolts. In this way, it takes time to remove the bolts one by one during disassembly. After the cleaning is completed, the bolts need to be tightened one by one, which will greatly increase the time spent on the entire cleaning process, making it inconvenient to clean and replace.
