These are relatively coarse screens and hole sizes typically range from 0.8 mm to 3.2 mm. Consequently, perforated screens are only suitable for removing general pipe debris. For steam, a Y-type strainer is the usual standard and is almost universally used. Its body has a compact cylindrical shape that is very strong and can handle high pressures. It is literally a pressure vessel, and it is not uncommon for Y-type strainers to be able to handle pressures of up to 400 bar g. The use of strainers at these pressures is however complicated by the high temperatures associated with steam at this pressure; and subsequently exotic materials such as chrome molybdenum steel have to be used. Y strainers have an arrow from inlet to outlet. It is important to install them in this orientation for proper filtration. What kind of end connections are available? A micron (micrometer) is a unit of length that's used to measure tiny particles. For scale, a micrometer is one thousandth of a millimeter or about one 25-thousandths of an inch. What is mesh size?

When there is direct injection of steam into a process, which may cause contamination of the product. There are different kinds of Y strainers on the market designed to meet various industry needs. Keep the following criteria in mind: The necessary frequency for cleaning the Y strainer depends on the process, mesh size, and materials being filtered. Close off any valve connections to both sides of the strainer, loosen the plug at the end of the filter leg, and empty the collected material from the filter. Y strainer selection criteriaArguably the most popular simplex strainer types on the market, basket and Y-strainers have their distinct advantages and disadvantages. Both have the edge over other inline filter strainers for various application types. However, each has certain qualities to bear in mind when choosing between these pipeline ancillaries. Basket strainers are used in a vast range of applications where flow can be interrupted to allow the removal of the basket for periodic cleaning. They are usually mounted horizontally into the pipeline, however on fabricated units, line connections can be orientated to suit customer requirements. Minor modifications can also be made to enable the installation into downward flow vertical pipelines. Select the housing material based on the application's environment. To do this, it's necessary to understand the chemical resistances of the materials. Are Y strainers affordable?

A Y strainer is a one-way strainer, so ensure the arrow that indicates flow direction will be pointing in the right direction. Where dirty steam may cause rejection of a product or process batch due to staining or visible particle retention. A simple Y strainer can keep these components, which are some of the most valuable and expensive parts of the pipeline, protected from the presence of pipe scale, rust, sediment or any other kind of debris. Y strainers, also referred to as wye strainers, are available in various designs and connection types. Y strainer design All of the simplex and duplex basket strainers available from BM Engineering Supplies are expertly crafted from cast iron by respected manufacturers, Leengate Valves . Benefits of using a cast iron basket strainer The outlet and inlet of the unit is 60.3mm/(2″ pressure) ID, with the addition of hostails or reducers this unit can be used in conjunction with any system

To conclude, the higher open ratio areas and improved holding capacities of basket strainers make them the go-to choice for most liquid filtration applications with batch processes or those that require occasional interruptions to the flow. . Y-strainers, on the other hand, are better equipped for inert gases or liquid applications requiring very low particle loading. Buy inline filter strainers EPDM: EPDM is similar to fluoro rubber but has different chemical resistances and working temperatures ranges. Learn more in our chemical resistance of materials guide.

It is advised that two gate valves are fitted to either side of this unit, ensuring all water is shut off when the baskets are being emptyed (1.5″ Valterra gate valves fit directly into the inlet and outlets) The basket type or pot type strainer is characterised by a vertically orientated chamber, typically larger than that of a Y-type strainer. 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 steam pipelines. Basket strainers are synonymous with the term “simplex strainer”, despite other strainer types belonging to this family. Much like Y-strainers, their name derives from their shape. Because of how the basket element seals within the chamber, as well as the location of the drain port itself, these inline filter strainers favour a horizontal installation.

In addition, it can be helpful to see examples of the mesh sizes of certain particles, as shown in Table 2. Mesh Size

The central part of the unit is the strainer basket which removes and retains the harmful contamination. The basket is secured via a spring loaded handle which is compressed by the strainer cover. Baskets are manufactured from perforated plate and, for finer degrees of filtration, baskets are lined with mesh linings which can be either permanent fixtures or removable. BM Engineering Supplies can provide your business with stainless steel Y-strainers from hygienic specialist manufacturers, INOXPA . Benefits of using a stainless steel Y-strainer A Y strainer is most valuable in an environment that requires constant protection from debris and contamination. Some of the most common applications are the following. Steam applications Example: In the food industry, and for the sterilisation of process equipment in the pharmaceutical industry.Basket strainers are also available in duplex styles as well as the standard singlex variants. Duplex basket strainers do not require shut-off when they become clogged or need to be cleaned. This means that they can be serviced without interrupting the flow of process fluids. As such, a duplex basket strainer would be prefered for continuous flow applications wherever businesses require systems to run without any downtime. Natural gas and air applications tend to have a low operating pressure, so proper sizing to reduce a pressure drop from inlet to outlet is important. FAQs How should I install my strainer? There are various material options for the strainer's housing and seal. The variety of housing materials fit well with certain environments and media. The seal helps to extend the life of the strainer. Housing materials These are formed by punching a large number of holes in a flat sheet of the required material using a multiple punch. The perforated sheet is then rolled into a tube and spot welded together. Liquid applications tend to become infiltrated by sand and gravel, and Y strainers can help keep those particles out to ensure the liquid stays clean. Especially when they work in tandem with other water-handling applications, these strainers can protect important (and expensive) equipment from damage, corrosion, or clogs that could result from such contamination.
