To purify oil from mechanical impurities in the central oil collection points (COCP) as well as in case of oil inter-field and main pipeline transportation, there used filtering equipment, in particular, strainers (S). Washing of a strainer’s filtering element requires its periodic removal from the housing, which entails spilling of oil-containing liquid onto the ground and polluting of the environment. A significant drawback of the basic design of a strainer’s filtering element is the extremely low fineness of filtration, which can lead to failure of the working bodies of oilfield pumps and end seals of main pumps. In addition, high hydraulic resistance when the filter element is clogged often leads to an abrupt increase of pressure in the strainer and crushing of the filtering element. The article proposes a new design of a filtering element based on a wiry-permeable material (WPM), which is lightweight, has low hydraulic resistance, and has high regenerative properties during flushing. WPM manufacturing technology allows adjusting almost any required fineness of oil filtration, ensuring an increase of the overhaul period of oilfield and main oil pumps operation.
