As Scotland’s premier distributor of pipeline strainers and ancillary equipment, we can share our years of industry expertise to help you understand everything you need to know about Y-type strainers vs. T-type strainers.

What is a Y-type strainer?

Y-type strainers are used predominantly in liquid applications for protecting downstream equipment from particles, such as dirt, which might otherwise affect performance if left untreated. Most Y-type industrial strainers can also work effectively in steam applications, as well as those that deal with inert gases or air.

While Y-type strainers can be fabricated to accommodate specific application requirements, the vast majority of Y-strainers are non-customisable as standard. Y-type strainers are available in sizes from 1/4" to 10" and can be manufactured from a variety of materials, including cast iron and steel, bronze and AISI 316L stainless steel. They also feature either a screwed or bolted cover for screen access and to ensure that, when opened, process fluid is drained effectively.

Y-type strainer benefits

• Superior flushing capabilities thanks to inherent built-in blow-down ports.
• Better value for initial costs.
• Faster shipment times due to their status as set items.
• Offers more overall flexibility.
• Wider selection of materials for construction.
• Broader range of pressure classes.
• Larger open ratio areas than T-type strainers.

What is a T-type strainer?

T-type strainers are mostly custom-fabricated industrial strainers that are usually manufactured from pipe materials. This allows them to offer unique features, such as quick-opening style covers or the addition of a ventilation port and differential pressure taps.

T-type strainers can also offset the inlet and outlet by 90 degrees, which forms an elbow-shaped strainer. This can benefit applications with space constraints. Typically, they are supplied in larger sizes, beginning at 2”. However, because they are fabricated industrial strainers, this generally results in extended lead times when ordering directly from manufacturers, as opposed to regional distributors such as BM Engineering Supplies.

T-type strainer benefits

• Quick opening style covers.
• Additional vent ports and differential pressure taps.
• Higher flow capacity despite smaller open ratio areas, thanks to a straighter flow path.
• Chamber covers can be opened without process fluid draining out whilst installed horizontally– which is beneficial in more hazardous processes.
• Better suited to transferring fluids at higher velocities.
• Ideal for larger pipeline applications which need quick access to the strain.

Y-type strainers vs. T-type -strainers: Which is better?

To answer the question of which is better – T-strainers vs. Y-strainers depends entirely on the needs of your business.

For example, if you are looking for a cost-effective straining solution from an industrial strainer that can offer more flexibility, then purchasing a Y-type strainer might be the way to go.

Alternatively, T-type strainers would be the preference if your pipeline application deals with more viscous fluids that need transferring at higher velocities or a strainer that has a higher flow capacity.

T type strainers have a rich history that dates back to their invention in the early 20th century. These ingenious devices have played a crucial role in various industries, from oil and gas to chemical processing, ensuring the smooth operation of machinery and equipment. In this comprehensive article, we delve into the origin, evolution, and significance of T type strainers, shedding light on their essential role in today's industrial landscape.

The Birth of T Type Strainers

The concept of T type strainers was first conceived by engineers seeking an effective solution to prevent the ingress of solid particles and debris into sensitive equipment. This need was particularly pressing in industries where precision and reliability were paramount, such as the rapidly growing oil and gas sector.

In the early 20th century, as oil exploration and drilling activities expanded, so did the demand for robust filtration systems. Traditional filters were often inadequate in handling the harsh conditions of these industries. Engineers recognized the need for a more efficient and versatile solution, and thus, the T type strainer was born.

Evolution and Design

Over the years, T type strainers underwent significant evolution and refinement. The original design consisted of a simple T-shaped body with a mesh or perforated screen to capture solid particles. However, as technology advanced and industries became more specialized, so did the design of these strainers.

Today, T type strainers come in various configurations, materials, and sizes to cater to the diverse needs of different industries. The core principle remains the same: they remove unwanted debris from flowing fluids, ensuring the integrity of pipelines and the longevity of equipment.

Significance in Modern Industry

T type strainers have cemented their importance in modern industry, serving as the first line of defense against contaminants that can compromise the efficiency and safety of operations. Here are some key reasons why these strainers are indispensable:

1. Protecting Equipment

In industries like petrochemicals and refining, machinery is exposed to harsh conditions and corrosive substances. T type strainers act as guardians, preventing abrasive particles from damaging pumps, valves, and other critical components. This protection not only extends the lifespan of equipment but also reduces maintenance costs.

2. Maintaining Product Quality

In the food and beverage industry, maintaining product quality is paramount. T type strainers play a crucial role in ensuring that the final product is free from impurities and contaminants. This not only meets regulatory standards but also upholds the reputation of the brand.

3. Enhancing Safety

Industries dealing with hazardous materials, such as chemicals and gases, rely on T type strainers to enhance safety. By removing potentially dangerous particles, these strainers mitigate the risk of explosions or leaks, protecting both personnel and the environment.

4. Improving Efficiency

In fluid-handling systems, any disruption can lead to decreased efficiency. T type strainers help maintain a consistent flow by preventing blockages and reducing the frequency of unscheduled shutdowns. This results in improved productivity and cost savings.

Disadvantages of T (TEE) Type Strainers

In the Petrochemical Industry, there has been a significant push to reduce costs over the past decade. Consequently, many contractors have opted for T-Type strainers in permanent applications due to their cost-effectiveness. They are often chosen because they represent the most economical strainer option with their integrated housing.

However, when considering T-Type strainers for permanent applications, it's essential to acknowledge potential issues, especially in cases of substantial dirt loading. This is primarily due to the design of the strainer's basket. The filter area of a T-Type strainer basket is approximately 250% of the inlet area. Therefore, when using a perforated plate, for instance, one with 3mm holes and 40% open area, the resulting open area ratio of the T-Type strainer basket is merely 40% of 250%, which equals the pipe bore area. Consequently, as the strainer begins to accumulate blockages, the open area decreases below the inlet area, leading to a rapid increase in pressure loss.

The situation becomes even more complex if the basket is lined with a mesh, as the mesh further reduces the basket's open area. For instance, combining a 10mm Square Hole Perforated Plate with 70% open area to support an 80 mesh wirecloth with 34% open area results in an open area percentage of the basket at only 23.8%. This leaves a reduced open area ratio of the basket compared to the pipe bore, and there's a significant pressure loss even before the basket becomes significantly blocked. Consequently, there is limited open filter area available to retain solid particles.

For permanent applications that require fine filtration, such as 80 mesh, it is advisable to consider the use of vertical basket filters. These filters typically provide the necessary filter area, with a standard open area of 200%, and they offer a substantial dirt holding capacity that ensures satisfactory performance in service.

In all cases involving T-Type strainers, it is crucial to monitor the pressure loss, ensuring it does not exceed 1.0 Bar in a dirty state. Excessive pressure can place undue stress on the basket, potentially leading to failure. Additionally, it's recommended to replace the baskets annually to prevent fatigue-related damage and subsequent basket failure. If a basket shows no signs of fatigue damage after a thorough inspection at the one-year mark, it may be operated for up to two years. However, it must be replaced after every two years of continuous operation without exception.

For permanent applications, our strong recommendation is to opt for vertical basket filters. These filters not only provide a filter open area of at least 200% as standard but also reduce the forces applied to the baskets during operation, minimizing the risk of failure.

Customization and Applications

One of the remarkable aspects of T type strainers is their versatility. They can be customized to suit specific applications, making them suitable for a wide range of industries, including:

• Oil and Gas: T type strainers are crucial in preventing clogs and damage in pipelines that transport crude oil and natural gas over long distances.
• Chemical Processing: The chemical industry relies on T type strainers to filter out impurities that can alter the composition of chemical compounds.
• Water Treatment: Municipal water treatment plants use these strainers to remove debris and sediments from water sources, ensuring clean and safe drinking water.
• Power Generation: T type strainers play a vital role in power plants, where they protect turbines and boilers from contaminants that can hinder energy production.

Conclusion

In conclusion, the origin of T type strainers dates back to a pressing need for effective filtration solutions in rapidly growing industries. Over time, their design has evolved to cater to a wide range of applications, making them indispensable in modern industrial processes.

Today, T type strainers continue to play a pivotal role in safeguarding equipment, maintaining product quality, enhancing safety, and improving efficiency across various sectors. Their adaptability and reliability make them a cornerstone of industrial operations.
