Wye ('Y') strainers and Pot (aka. Tee or 'T') strainers have many similarities, so how does one decide which style is the best fit for an application?

You can find more information on our web, so please take a look.

Similarities

Y and T strainers are both simplex style pipeline strainers designed for batch applications with a light particle load; to clean the internal screen requires interrupting the process flow.

Y Strainers

Although commonly used for liquid applications, the use of Y type strainers were initially for steam, air and other inert gases to protect downstream equipment from a "particulate upset condition" such as protecting steam condensers from rogue pipe scale.  Y strainers have a blow-down port for steam applications and this flushing capability is a characteristic that T strainers do not have. While blow-down may work for aqueous applications, the efficiency of flushing depends upon the particles retained not becoming embedded within the element.

Although it is possible to fabricate Y strainers to satisfy specific applications, the majority of Y strainers are cast items, thus non-customizable. It is common for Y strainers to be available in 1/4" through 10" sizes and because they are a cast item manufactured in foundry-pour based quantities, shipment is often made within just a day or two after receipt of an order. The available pressure class ranges and breadth of materials of construction (iron, steel, bronze, and 316SS) are also advantages of Y strainers.

The open area ratio (OAR) for Y strainers is typically a little better than T strainers; most of our Y strainers have a 3:1 OAR wheras the larger size T strainers have an OAR of <= 2.

Y strainers have a screwed or bolted chamber cover for screen access and are installed such that when opened the process fluid will fall/drain out.

T strainers are mostly a custom fabricated product, often manufactured from pipe. The advantage of a fabricated product is the ability to provide customized features, such as a quick-opening style cover, addition of a vent port or adding differential pressure taps. It is also possible to off-set the inlet and outlet by 90 degrees, forming an "elbow" shaped strainer which might be desirable when the installation area is constrained.

T strainers usually begin at larger sizes (2") and can be fabricated for 24" or larger pipelines. As a fabricated product, the lead times range from 8-12+ weeks (inclusive of generating approval drawings and manufacturing).

While the OAR for a T strainer is typically less than a comparable size Y strainer, its' flow capacity is higher. This is attributable to the flow path within a T strainer having a "straight-through" design as well as the convoluted element shape.

When installed horizontally, the chamber cover of a T strainer can be opened without the process fluid draining from the chamber; this might be a desirable feature with valuable or hazardous process fluids.

Summary

Y strainers typically offer the best value in terms of initial cost, lead time and overall flexibility which include materials of construction, pressure class, and inherent built-in blow-down port/drain.

T strainers are used when transferring fluids at higher velocities (equates to higher flow rates), for larger pipelines, applications that require special features and for quicker access to the straining element.

T-Strainer vs. Y-Strainer: A Comparative Guide

Although Y-type and T-type strainers perform similar functions in pipeline applications, they each have distinctive qualities that make them uniquely different. While both are effective industrial strainers for removing dirt from fluid systems and protecting valuable downstream equipment, it&#;s useful to know the differences between Y-type strainers vs. T-type strainers when selecting your strainer filter.

In this article, BM Engineering Supplies discusses the differences between T-strainers vs. Y-strainers. We will also offer our guidance on which strainer type you should choose for your pipeline application. 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.

  solid supply professional and honest service.

• 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

  t

  ransferring 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.
