The Y Strainer &#; Purpose and Application

Afbv Valve Product Page

When deciding which type of strainer to use, it is important to understand the specific purposes and differences that make a strainer unique. Wye strainers are no exception. While this strainer option is more flexible when compared with basket strainers, the y strainers have a very limited installation. The y type strainer purpose is a specific one and that is exactly what makes them ideal for the applications where they can be used. This means that understanding the y strainer purpose and the applications that benefit from it are the best ways to get the results that you are looking for out of this strainer!

The Y Strainer Purpose

The y strainer purpose is to remove unwanted particles from steam, gas, or liquid using a straining element typically made of wire mesh. Using this mechanical process in pipelines helps to protect everything from pumps to steam traps. Y strainers are sometimes designed with &#;blow-off valves&#; to make the cleaning process easier.

Perhaps the largest benefit that comes from the y type strainer is its flexibility. It can be installed in a vertical or horizontal position, depending on the users&#; preference. While this strainer type is already a cost-effective option, the size of y strainers can be reduced to save even more money. This also prevents using excess materials. Y strainers can be made of a variety of materials. The type of material you choose depends on the industry and application that is used. Any type of end that you might need is available as well. From socket to flanged, there is a y strainer out there with the end you need!

The ways in which y strainers can be customized are seemingly endless when compared with other types of strainers. However, the design of a y strainer must be appropriate for the application for this system to be successful. In order to get the right results, always be sure to know the application you are working with before buying a y strainer.

Y Strainer Applications

The industries where y strainers are best used are those that need constant protection from debris. The most universally common use for a y strainer is in steam applications. Due to its shape, a y strainer has no trouble handling the high pressure that steam applications endure.  

Y strainers are often used in liquid applications. Sand and gravel are two very common types of debris that pose a big threat to liquid applications. When combined with water handling applications, y strainers aid in the protection of equipment that would be otherwise damaged or clogged by various unwanted particles.

Natural gas and air applications also benefit from being used with y strainers. Much like steam applications, natural gas and air environments have high pressure levels. These applications are also expected to put up with high temperatures, something that y strainers can easily endure.

Because of the variety of industries and applications where a y strainer can be used, the materials and customization of these strainers must be done on a case-by-case basis. For example, carbon steel does not do well in extremely high temperatures or pressures, so it would be best to find a y strainer made of chrome-moly steel for steam or natural gas applications. Keeping in mind specificities when it comes to applications and industries will help ensure that you get the most from a y strainer.

Why Use a Y or Basket Strainer

As we talk about strainers, this might be a good time to review the general purpose of a strainer. A strainer is used to &#;strain&#; or &#;filter&#; contaminates in a piping system that could flow down the pipeline and damage more expensive pieces of equipment, or spoil a manufacturing process. In effect, a strainer could be viewed as a very inexpensive &#;insurance policy&#; to help protect the overall piping systems. Strainers are available in many materials, types, and end connections. These various options are designed to help the end user obtain the best possible straining device for their specific applications.

Strainers can be obtained in threaded ends, socket weld, butt weld and flanged ends. Higher pressures are also available in other special end connections. Body materials can range from iron, carbon steel, stainless steel, bronze and many special alloys. Some manufacturers even offer FRP units (fiberglass reinforced plastic) bodies, for significant corrosion resistance, at a lower cost and with a greatly reduced installed weight.

BS25 Basket Strainer

The selection of the straining element (screen or basket) is typically based on the line media (what&#;s going through the pipeline). The term &#;screen&#; is typically used in wye strainers, while &#;basket&#; is the term that is used in a basket type strainer. The internals of a strainer are really the internal screening, or filtering element. Additional factors include what may be flowing through the line, and the degree of straining that the customer has determined needs to take place. Pressure drops, line pressure, flow rate are just a few of the considerations that may be factored in. For more information regarding the selection of straining elements, see the blog post "Choosing the Right Straining Element".

The straining elements are generally made from a wire mesh type screen material or a perforation in sheet metal. In some cases, depending on size and pressure rating, a mesh unit may additionally include a perforation. Using a perforated material in conjunction with a mesh, may be best in providing greater strength and stability to the straining element.

Perforated Screen

Mesh Lined Screen

The standard basket or screen material in most strainers today is 304 series stainless steel. 316 stainless steel is also common (often used for additional corrosion resistance). Monel is also a material that can easily be provided by most manufacturers. There are many variations of mesh and perforations that are available along with various methods of construction, and support methods, based on specific applications.
