Custom Fabricated Simplex Strainers

 

Titan Custom Fabricated SImplex Basket Strainer

Custom fabricated strainers are for applications that require features not offered by cast simplex strainer designs.  Requirements for an ASME code stamp, flanged vent and/or drain ports, special coatings, positioning of the inlet/outlet nozzles, corrosion allowance and practically any other customization you can think of can be accommodated with a custom fabricated design.

 

This photo illustrates a multi-basket design for a large size pipeline, an improvement in ergonomics by reducing the weight of each clogged strainer basket.  It is easier to remove (4) smaller strainer baskets than a single large one.

 

Eaton, Titan and Keckley are all capable of manufacturing custom fabricated simplex basket strainers from carbon steel, 316SS and other alloys, although only Eaton and Titan have manufacturing facilities authorized to issue ASME code stamps; Keckley uses a 3rd party for code stamp requirements.

 

Fluidtrol, a manufacturer of non-alloy FRP simplex basket strainers can also "customize" their standard designs to satisfy certain design criteria, dimensions and nozzle orientations.

 

How do you choose which manufacturer to use?  Since the design is custom to your specifications, your decision will be mostly based upon pricing and lead time.  Eaton's North American manufacturing facility is located in Reynosa Mexico whereas Titan's is based in the USA.  Quality is top-notch for both, but some customers prefer to source American manufactured products.

 

Eaton and Keckley have a standard or "base" configuration for custom fabricated basket strainers for 150# and 300# pressure class designs.  You can use our differential pressure calculator to estimate the approximate clean differential pressure drop for the standard Eaton model 90 configuration.

 

Begin 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.

 

Ideally you want the initial clean differential pressure to be ≤ 2 PSIG and when the differential pressure increases by 5 PSIG it is time to clean the basket.  Since the differential pressure increases exponentially (assuming a constant particle load), it is important to prevent the differential pressure from nearing the 15-20 PSIG maximum sustainable differential pressure threshold.

 

If you require a very low differential pressure, select a larger size strainer until you reach the desired clean differential pressure; we can simply attach reduced size connection flanges to match your pipeline.  So essentially custom fabrication enables a design having a higher open area ratio and lower clean differential pressure drops.

The lead time for custom fabricated strainers are typically 6 to 12+ weeks and much depends upon the complexity of the design and current shop backlog.  The best way to proceed is to complete our strainer inquiry form which prompts you for all the information we require to provide a proposal.  We'll compare potential cast options with fabricated options and quote accordingly.  You may also call and discuss your application with an experienced sales engineer; people that have been in the field and truly understand key design criteria.
