How Do You Select The Y Strainer?

What are some factors to consider when selecting the Y strainer? There are several things to keep in mind when purchasing this specialized piece of equipment. Having the proper mesh size is important as it can prevent excess pressure drop and premature failure of mechanical components. A good strainer should have multiple sizes of mesh holes. The mesh size will determine how the product functions. Microns are a measurement of one-thousandth of a millimeter.

When selecting a Y strainer, make sure to consider the pressure. It is better to use a y strainer in pressures up to psi. Y strainers are also more versatile since they are able to attach to pipeline flanges in various ways. Depending on the material used, y strainers can be either threaded or welded. The material can be iron, bronze, carbon, or stainless steel.

How Do You Select the Y Strainer?

The Y strainer is a simple filtration device that is made up of two metal plates held together by bolts or gaskets. The plates squeeze against each other to form a tight seal. Fluid passes through the Y strainer and is discharged through the discharge port. This device prevents contaminants larger than the mesh from entering the machinery. It is a popular choice among industrial businesses that use water and other fluids.

  • Consider Pipe size

There are several factors to consider when selecting a Y Strainer. It is important to choose the right one for the system in question since a faulty one can cause considerable damage to the equipment and the environment. Consider the pipe size of the system and the pressure and temperature that you are working in when selecting a Y Strainer. Depending on the size and type of the system, you may need one that has a higher or lower pressure rating.

  • Consider Flow rate

There are a few important things to consider when selecting a Y strainer. Flow rate is one of the most important factors, as it will determine how much pressure you can safely reduce. The thicker the material, the slower the flow rate and the higher the chance of pressure reduction. Remember that the size of the pipes has no bearing on the acceptable pressure loss, so it is important to choose a strainer based on the flow rate and the size of the fluid. You can also consult a pressure drop chart online to help you choose the appropriate strainer.

  • Consider Material requirements

Another thing to consider is the size of the Y strainer. A smaller one will fit on a smaller pipe and will be less expensive, but it may be undersized or oversized and, therefore, not be suitable for your application. Carbon steel Y strainers are the most preferred option for the oil and petrochemical industries because they are better able to resist thermal and mechanical shock. Furthermore, they are used in higher pressure applications where iron piping is not acceptable.

  • Consider Temperature and pressure range

The temperature and pressure range of a Y strainer should be considered when selecting one. Whether the strainer is installed on a metal pipe or a polyethylene piping system, you must be sure to choose the right materials. The plastics in a Y strainer may break or be distorted by shock pressure. When choosing a Y strainer, make sure to choose the right materials to prevent the strainer from rusting or developing other issues.

  • Consider Maintenance

Y strainers are important components of industrial equipment that has fluid piping systems. The &#;Y&#; shape of these pipe fittings allows them to separate solids from fluids without disrupting downstream components. Y strainers are generally smaller than basket-type strainers and require more frequent cleaning. While this isn&#;t a huge issue on steam systems, they can introduce large debris during commissioning. If you&#;re considering a Y strainer for your fluid piping system, consider the following tips to choose the right one for your needs.

Types of Y Strainer Body Materials

Y Strainer Material Types / Materials of Construction

It&#;s important to choose the right type of Y strainer for specific piping systems. Y strainers are made of various materials, including metals and plastics. They are an essential part of pipelines in helping prevent solids and debris from mixing into the liquid in a flowline. They also help protect the longevity of other equipment in piping systems and prevent downtime from unscheduled maintenance and repairs by eliminating unwanted solids and particles before they get to crucial pieces like pumps, steam traps, flow meters, and control valves.

Different Body Materials Used

The materials Y strainers are made of determine the types of conditions and applications they are best suited for. They can be used in such applications as steam, liquid, natural gas, and air pipelines. Below are some of the most used Y strainer materials and suggested applications.

Stainless Steel

Stainless steel Y strainers are commonly used for applications in which freedom from contamination and resistance to high corrosion is required. It&#;s the preferred material for food, chemical, and pharmaceutical industries. However, stainless steel may be more expensive than some of the other Y strainer material options. (View products)

Cast Iron

Cast iron Y strainers are typically used in piping systems that do not have high pressure and high temperatures and where the system isn&#;t exposed to high thermal or mechanical shock. Cast iron is the most commonly used strainer body. It&#;s used for bigger-sized potable water lines and various non-potable water systems as well as a variety of other product and process uses.

Carbon Steel

Y strainers that are made with carbon steel are used with high pressure and temperatures and are very resistant to thermal and mechanical stress, because they are strong and durable. They are also used for applications that have a fire risk. Carbon steel bodies are used primarily in the oil and petrochemical industry. (View products)

Bronze

Bronze Y strainers are an effective option for removing dirt, rust, and adhesives from piping systems. Bronze body y strainers are often used in brackish, saline, and seawater applications, as well as for potable water services. However, it is more expensive than some of the other options. (View products)

Brass

Brass Y strainers are an affordable solution for various applications. Brass is often used for upstream installations to protect regulators, pumps, and control valves from unwanted solids like rust and pipe scale. (View products.)

PVC and CPVC

Y strainers made from PVC or CPVC (polyvinyl chloride or chlorinated polyvinyl chloride) are an ideal choice for removing dirt, debris, and other solids from commercial and industrial piping systems. They can withstand high pressures and can be installed vertically or horizontally, making installation convenient. While PVC can only tolerate temperatures up to 140° degrees Fahrenheit, CPVC can withstand temperatures as high as 200° Fahrenheit. They have excellent corrosion and chemical resistance. PVC and CPVC are versatile materials, making these types of Y strainers suitable for a wide range of applications. Additionally, they are inexpensive compared to other options.

Can You Mix Metal & PVC (Plastic) Strainers?

With so many different materials, you may wonder if you can mix metal and plastic components in piping systems. Perhaps you need to replace a Y strainer in a piping system that is metal. Plastic Y strainers are typically less expensive than those made of stainless steel or other metals. But, will it work to use a plastic Y strainer in a metal piping system?

Plastic Y strainers can be used in metal piping systems; however, it&#;s important to be aware of some factors that can affect how successful your application ends up being. When deciding whether to use a plastic Y strainer in a metal pipeline, there are three main considerations:

  1. Temperature and pressure rating. Often times, metal components are used in piping systems because of higher operating temperatures. If you plan to use a plastic Y strainer in a metal system, make sure that the temperature and pressure range of the application is within the plastic Y strainer&#;s acceptable range.
  2. Chemical resistance. It&#;s also important to consider the potential for shock pressure generation (water hammer) in the piping system, which could prove to be too harsh for a plastic Y strainer, causing damage and resulting in downtime and more maintenance. Look for things like a system flow rate that&#;s more than 8&#; per second, positive displacement pumps, fast opening or closing actuated valves, quick starting pumps, and solenoid valves, before you mix materials in a piping system.
  3. Installation and stress. The stress that will be placed on the plastic Y strainer is a critical installation consideration. Stress can cause problems or damage right away, or it can accumulate over time and show up sometime in the future. So, it&#;s important to make sure that the metal and plastic components are properly aligned. If they have to be forced into place, there will be problems at some point. Additionally, be sure to watch out for misalignment of the mating pipe flanges, as well as oversize face-to-face dimensions of the flanges. To avoid thermal expansion, you may want to use expansion joints to compensate, or you can try installing plastic pipe on the outlet and inlet of the Y strainer to keep it from attaching directly to metal pipe.

Choosing the Right Material Type

Not all piping applications are the same. As a result, it&#;s important to choose the right pipeline components, made of the right type of material, for the specific job. Y strainers are available in various materials, including those highlighted above. You can see that each material is ideal for specific uses and types of piping systems. When you use Y strainers made of the right material for your pipeline, it helps ensure efficient operation, reduced downtime, and longer lifespans for crucial equipment.
