asket Strainers are generally used where high flow capacity is required. Basket Strainers are also available in a duplex style which consists of two parallel basket Strainers and diverting valves, which permit diversion of the flow through one of the Strainer elements while the other element is being serviced-an essential feature where the flow cannot be interrupted. Strainers do not necessarily remove only dirt. They take out material that is not wanted in the fluid and this can sometimes be a valuable product that may be saved. Basket strainers are designed for installation in horizontal lines. They are commonly used for liquid service applications.
"A closed vessel with cleanable screen element designed to remove and retain foreign particles down to 0.001 inch diameter from various flowing fluids."
When the filter is operating, the water to be filtered enters the strainer basket thru the inlet, flows through the filter panel, and enters the desired pipe through the process flow outlet. Particle/solid impurities present in the water are stuck inside the basket filter screen. With this continuous flow, more and more particles are caught, and the speed of filtering gets slower over time and the filter hole would get narrower and smaller, this results in a pressure differential between the inlet and the outlet. A pressure gauge installed before and after a strainer will indicate a pressure loss due to clogging. This can help in establishing a maintenance schedule for cleaning the strainer screen. Extra screens can useful in keeping the system operating during the cleaning process. As the gap between inlet and outlet pressure exceeds the fixed value, the differential pressure sensor transmits the electrical signal to the controller, and the control mechanism begins the drive motor to rotate the shaft via the transmitting element. At the same time, the blowing port is opened and discharge of debris takes place from the blowing port.
Titanium strainers are made from Titanium, Tantalum, Nickel, Zirconium, Hastelloy are our main focus. Recently we have supplied Titanium strainers to one of our valuable customer and the product photo is attached below.
Warning: Before the removal or loosening of any bushing, cap, plug, or cover on a strainer, extreme caution should be exercised to ensure there is zero pounds pressure in the system.
Only after the system has been depressurized, should the strainer be drained for service. Service on a pressurized Strainer can cause serious injury and/or property damage.
Basket strainers with a closed bottom basket can be cleaned by removing the cap or cover and pulling out the basket screen for service. If the strainer screen is bottomless the blow-off plug can be removed allowing it to be drained and cleaned like a Y-strainer.
Care should be taken in cleaning screens. After removing a screen, it should be soaked in a cleaning solution or cleaned by using a brush. Do not allow trapped material in the screen to harden, as it will be difficult to remove. A regular cleaning schedule is recommended to avoid screens from becoming clogged.
