Brass Compression 15mm 22mm Inline Y Strainer with Stainless Steel Mesh Debris Filter (22mm)

Product Information

The chart below is a handy resource to help convert from mesh to micron (or vice-versa). Mesh Screen There are number of different types of self-cleaning strainer, which enable the build up of debris on the screen to be removed without shutting down the plant. The cleaning process can be initiated either manually or automatically; furthermore, strainers that are automatically cleaned can usually be set to clean either on a periodic basis, or when the pressure drop across the strainer increases. 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 criteria 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 inline strainer unit features two threaded retaining nuts and sealing “O” rings, once unscrewed the base of the unit will be released enabling the baskets to be cleaned.

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.

The Y strainer can be installed vertically or horizontally, but the filter leg must be pointing downwards to ensure that any filtered material does note interfere with the main flow. 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 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 designTo 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 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. 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 When there is direct injection of steam into a process, which may cause contamination of the product. 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?

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.

Even when manufactured from stainless steel, Y-strainers are also a much more cost-effective inline filter strainer option than basket strainers. They also offer a more compact straining solution, which makes them ideal for applications limited by space. Most Y-strainers can also provide higher operating pressure ranges than basket-style strainers, despite their higher flow capacities. It's important to take the time to size the mesh filter correctly. A mesh filter that is too small or too large can negatively affect the system. If the filter is too small, there will be a higher pressure drop from inlet to outlet. Additionally, removing too much debris from the flow can clog the filter and increase the pressure drop. If the filter is too large, the performance and life span of the downstream equipment can be negatively effected. Material options use some form of mechanical scraper or brush, which is raked over the screen surface. It dislodges any debris that is trapped in the screen, causing it to fall down into a collection area at the bottom of the strainer.

The problem with this dimension is that the screens are two-dimensional and the particle must reach the hole in a certain orientation. Therefore, if a long thin particle reached the strainer ‘face on’, it may be allowed to pass through the screen. However, if it hit the hole ‘side on’ it would be stopped. If this is likely to be a problem, a finer mesh should be used. There is no one-size-fits-all Y strainer that meets every need. That's why it's important to understand the application requirements before selecting a strainer. Typical Y strainer applicationsUsed whenever high flow capacities are required, basket strainers are serviced by removing the cover. This will provide access to the basket which can then be removed, cleaned and replaced as required. Why you might consider using a duplex basket strainer 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 In addition, it can be helpful to see examples of the mesh sizes of certain particles, as shown in Table 2. Mesh Size Although there are exceptions, size for size, Y-type strainers have a lower dirt holding capacity than basket strainers, which means that they require more frequent cleaning. On steam systems, this is generally not a problem, except where high levels of rust are present, or immediately after commissioning when large amounts of debris can be introduced. On applications where significant amounts of debris are expected, a blowdown valve can usually be fitted in the strainer cap, which enables the strainer to use the pressure of the steam to be cleaned, and without having to shut down the plant.
