Stainless steel basket filter is a widely used pipeline filtration device, with its core filtering element being a basket shaped filter basket made of stainless steel mesh, installed in pressure vessels made of carbon steel or stainless steel. Mainly used to intercept and remove solid impurities with relatively large particle sizes in pipeline fluids, such as rust, sediment, sealing debris, etc., to protect downstream key equipment such as pumps, valves, instruments, etc. from damage. Its characteristics are high circulation capacity, low pressure drop loss, and the filter basket can be repeatedly cleaned and used. As a fundamental and effective pre-treatment equipment in industrial pipeline systems, it is widely used for fluid purification in petroleum, chemical, water supply, heating and other systems.
