oct 22, 2017 size for size, the pressure drop across a basket strainer is less than that across the y-type as it has a greater free straining area, which makes the basket type strainer the preferred type for liquid applications. As the dirt holding capacity is also greater than in y-type strainers, the basket type strainer is also used on larger diameter when comparing simplex basket strainer designs, a higher Cv value indicates it is capable of handling a given flow rate with less restriction the difference in Cv values is a reflection of the internal finish and geometry of the strainer body which happens to dictate the size and design of the strainer basket.
conical strainer pressure drop calculation. any flow rate over 150 gpm will most likely require a basket strainer because of pressure drop considerations strainers are usually sized so that their start up pressure drop is no greater than psi with a line velocity not to exceed fps On a per size basis basket strainers exhibit less pressure loss than y-strainers get pricepressure drops for strainers pressure drop curves for strainers. notes: these charts are based on the flow of clean water at ambient temperature. consult our engineering department for pressure drop information for steam, gases or viscous fluids.
As an example, the downstream pressure should never fall below the npshr of a pump. perforation size or screen size. the strainer should be slightly smaller than the smallest piece of debris that is expected to flow through it. If the perforations are too small, a high pressure drop could develop across the strainer and cause it to fail.application of industrial valves, strainer, filters, sight glass, sight flow indicator in various industries: thermal power plant, captive power plant, hydro power plant, gas based power plant, naphtha based power plant, nuclear power plant, metal industries, rolling mill, steel plant, zinc smelter plant, rubber plant, tyre manufacturing industries, corrosive chemical plant, petrochemical

jun 11, 2013 strainers international site for spirax sarco. this tutorial considers the range of strainer and filter types in use and how to size for size, the pressure drop across a basket strainer is less than that using the empirical formula in equation there are three basic configurations of temporary strainers, namely the conical type, the basket type and the plate typestrainer shall be designed and manufactured to meet asme .1, asme or asme andor asme section viii div. the strainer body shall be fabricated steel or other specified material and inletoutlet connections shall be in line. the strainer shall have a single basket with a slant top. the strainer shall have a bottom blowdown outlet.
any flow rate over 150 gpm will most likely require a basket strainer because of pressure drop considerations. strainers are usually sized so that their start up pressure drop is no greater than psi, with a line velocity not to exceed fps. On a per size basis, basket strainers exhibit less pressure loss than y-strainers.consequent pressure drop losses. In reality, tests have shown a threshold value in relation to strainer OA and pressure drop losses, mack iron r&d has found strainers with approx. 150% OA configurations to be optimum. above 150% oa, operat- ing pressure drop does not improve with increasing oa. for example, theory predicts a 300% OA strainer to
basket strainer bucket strainers. basket strainer or bucket strainers are a closed vessel with a filter screen inside it. they have a high capacity to retain foreign particles and hence widely used. basket strainers are used only in horizontal lines; mostly for liquid services with high flow capacity.fabricated strainers products: standard line of temporary, tee, basket and duplex strainers. custom strainers to meet individual space or performance requirements. automated self-cleaning strainerssystems. screens and baskets. size range: and larger end connections: flat faced raised face rtj flanged butt-weld
through a duplex strainer, pressure drop is higher than through the equivalent size single basket strainer. geometric strainers where cost is of prime importance, a geometric strainer may be installed between flanges in a pipe line. variations of geometric strainers include cone truncatedyou can use the differential pressure charts below to estimate the approximate clean pressure drop across a temporary cone strainer or temporary basket strainer.the chart data is based upon water and perforations ranging from to 116
titan flow control, inc. also offers downloadable pressure drop charts for your convenience. click on the images to the right to download the adobe pdf sheets for titan fcis strainer and check valve models. for additional help determining the pressure drop for a titan In sizes above a single basket strainer will generally create less pressure drop than a strainer. basket strainers are normally installed in a horizontal pipeline with the cover over the basket at the top. cleaning of the strainer is generally simple and no draining is required.

mar 19, 2008 the strainer manufacturers ive talked to dont seem have a decent method of determining pressure drop. things that are known about the filter material are open area and mesh size. also can determine total conical area from dimensions of assembly. what equations can be used to determine pressure drop for a gas?temporary conical strainer pressure drop liquids temporary conical strainer pressure drop liquids note pressure drop curves are based on water flow with standard screens.
well designed basket strainer should have an open ratio of at least to anything less may cause excessive pressure drop. the ratio is calculated with a clean basket and as the basket begins to clog the ratio will drop. unless there is a wide safety margin the area through the basket may quickly become smaller than the pipe area.
