EATON MODEL 91 T STRAINERS

Custom Fabricated T Strainers

Eaton model 91 T strainertee strainer

 

Tee strainers are a style of compact custom fabricated simplex strainer to satisfy requirements that a cast Y strainer cannot, such as being constructed with a corrosion allowance, having an ASME code stamp or made with an oversized body for a higher open area ratio.  We wrote an article "How to Choose Between a Wye (Y) and T Strainer" if you are not sure which style is most appropriate for your application.  In addition to being a compact design, T strainers can be installed vertically if the flow path downwards, just like a Y strainer.

Options for Custom Fabricated T Strainers

CRN registration, ASME U code stamp, ASME UM stamp (where applicable), Welding procedures (WPS, PQR, WPQ), Internal/External coatings per customer's specification, Non-destructive examination (L.P., X-ray, PMI, UT, MT, LD) and Corrosion Allowance.

 

Documention Available for Custom Fabricated T Strainers

NDE report, Seismic calculations, Wind load calculations, ASME code calculations, Certified material test report, Domestic export documentation.

When comparing the flow coefficient values of T strainers and basket strainers you'll notice that they are very similar, meaning you can take advantage of the compact tee strainer size without sacrificing (making higher) your differential pressure.  This is possible due to the special  convoluted screen design of the Eaton model 91 T strainer which increases the total filtration area.

The greatest difference between T strainers and basket strainers is the volume of particulate which can be retained.  The screen design and vessel size for T strainers is less than it is for a corresponding size basket strainer, which means that T strainers are better suited for applications having a low percentage of particulates (similar to Y strainers).  This makes T strainers ideal as condensate and boiler feed pump suction strainers due to their low clean differential pressure and the expected low volume of particulate.

We offer two different basket chamber cover designs, the bolted and quick-opening style.  The bolted style has 4 or more studs and nuts for retaining the cover.  The quick-opening style has a hinged cover and utilizes swing-bolts for quicker access to the vessel.  Although we do offer a quick-opening cover for the 300# class tee strainers, we do not list them online, so inquire about this if desired.

 

It is important to check your clean differential pressure, some of the smaller sizes have lower capacities than their basket style version (Model 90 simplex strainers).  You can calculate the approximate clean differential pressure drop by selecting the strainer connection size, inputting your flow rate (GPM), inputting the specific gravity if other than water (sg of water = 1) and select the viscosity range if other than water (SSU of water = 30).  Click "Update" to refresh the data and be sure that the clean differential is ≤2 PSI for the intended basket retention.
