Strainers and Filters

Strainers and filters are devices that mechanically remove solids from flowing fluids. Strainers are often employed in pipelines to protect downstream equipment, such as heat exchangers, pumps, compressors, flowmeters, spray nozzles, turbines, and steam traps, from the detrimental effects of sediment, rust, pipe scale, and other extraneous debris. This module will list the functions of strainers and filters and describe Y strainers and duplex, twin, back-flushing, automatic self-cleaning, and scraper basket strainers as well as surface and depth type filters.

•Identify the functions of strainers and filters •Define "strainer" and "filter" •Differentiate between strainers and filters •Describe the design and operation of Y strainers and duplex, twin, back-flushing, automatic self-cleaning, and scraper basket strainers •Describe surface type and depth type of filters •Identify and describe the following types of filters: cartridge, bag, hydraulic, panel, oil and air filters
