Basket Strainer Vs Y Strainer: All You Need to Know

A strainer is a tool that is used to remove debris from liquids and gases in a piping system. The strainer works to protect equipment such as valves, pipes and pumps from getting damaged by solid particles. It is a very crucial part of a production system and should not be ignored. There are different types of industrial strainers available in the market today. The most common strainers include basket strainers, y strainers, and t strainers, among other types.

Depending on your system configuration and the amount of filtration work you have, you will be able to choose an industrial strainer that works for you. In this blog, we are going to compare the basket strainer vs y strainer and help you choose between the two. We will also look at how the two types of strainers are applied in different industries.

 

The Basket Strainer

A basket strainer is an equipment that uses a mesh screen to trap solid particles from liquids and gases in a horizontal piping system. They are used to protect other critical parts of the system from damage by solid debris. Basket strainers are used in pipelines with high-velocity flows. They can be installed as one basket, also known as a simplex strainer, or two baskets, known as a duplex strainer. 

The duplex basket strainer has the upper hand to the simplex type due to the fact that you can actually clean one side of the strainer as the other basket continues with the filtration process. With the simplex strainer, the system has to stop during cleaning which results in frequent system downtimes. While buying a basket strainer, you might want to consider investing in the duplex strainer as opposed to the simplex version. Various basket filter manufacturers also provide guidance on the best strainer for your needs.

The mesh screen of the strainer is designed depending on the job purpose. A mesh with extra tiny spaces usually requires more cleaning due to the frequent clogging, while one with large spaces will most likely allow some particles to pass through. Basket filter manufacturers understand this perfectly and will always ensure that the measurement of the mesh openings is in good proportion with the kind of filtration job the strainer will perform.

 

Applications of the Basket Strainer

The basket strainer is used in different industries and is considered the most effective type of strainer for large pipelines with high flow velocities. Some of the most common applications of the basket strainer include;

Strainers are essential components in pipe systems because they remove debris from the system to keep downstrain components safe and functioning. Y strainers are easier to install and maintain. T strainers, on the other hand, have lower pressure drop and are better suited for heavy-duty applications. This article goes further into the differences between these two types of strainers.

Correctly incorporating strainers into a pipe system protects equipment and processes. They are critical for applications that require clean fluids. The strainers filter out dirt, debris, rust, jointing compound, weld metal, and scale. By filtering out debris, downstrain components will be protected which reduces maintenance costs and downtime, allowing optimal productivity.

Y type vs T type strainers

Y and T type strainers are commonly used to protect equipment in a piping system. The key differences between t strainer and y strainer are their design, installation orientation, and cost.

Design

A T strainer (Figure 1 left) has a T-shaped body, a removable strainer basket that sits inside the body, and a top access port that opens to provide access to the basket when it needs to be cleaned or replaced. T strainers can collect more particles without getting clogged than Y strainers can, therefore T strainers have lower pressure drop across the strainer.

A Y strainer (Figure 1 right) has a compact, y-shaped design. The mesh strainer branches off from the main flow path, so captured particles do not sit in the way of the flow. However, Y strainers are not designed to hold a lot of debris and can quickly clog. Therefore, Y strainers are better suited to cleaner media and low-pressure applications.

Installation orientation

Due to its design, a T-shaped strainer can only be installed to horizontal piping and must be facing upwards. This limits the design possibilities of the system. A Y-shaped strainer, however, can be installed on horizontal or vertical piping. The only important aspect is that its filter leg must be facing downwards. The Y-shaped strainer has more versatility when fitting into a pipe system.

Cost

When the best strainer is the least expensive strainer, Y strainers are the better choice. Y strainers have a cast housing and therefore are less expensive than T strainers. Reducing the necessary size of the strainer as much as possible before purchasing can also help reduce costs.

Screen types

Strainers used in pipe systems are also differentiated by the type of screen they have. The two primary types of screens are perforated screens and mesh screens.

  • Perforated screen: A perforated screen strainer is a single sheet of metal with holes drilled into it in a regular pattern. This type of screen is typically used for applications that focus on capturing relatively large particles only.
  • Mesh screen: A mesh screen consists of woven or knitted material, typically metal wires. This creates a grid-like pattern with small openings between wire and fibers. Mesh screen strainers are better suited for filtering relatively small particles.

Materials

The following list consists of the most common materials used for y and T strainers.

  • Carbon steel: Carbon steel is best suited for high-pressure and temperature applications. If there is a fire hazard, choose carbon steel.
  • Bronze: Bronze is chosen in saltwater environments.
  • Cast iron: Cast iron is the most cost-effective choice for moderate applications.

FAQs

What are the differences between T and Y strainers?

The primary difference is their shape. Y strainers have a Y shape and T strainers have a T shape. Y strainers are suitable for clean media whereas T strainers can handle larger particles.

What does a strainer do?

A strainer stops particles, such as rust and scale, from entering and damaging important and costly system components.
