Custom Fabricated 316SS Steel Duplex Strainers

Model 950 custom fabricated duplex strainer

Our custom fabricated duplex strainers for 2" to 16" size pipelines are listed below and includes perforated 316SS strainer baskets.  All flanged connections are ANSI class 150# and rated for 150 PSI at 150°F.

 

Custom fabricated duplex strainers utilize butterfly valves for diverting flow, having a cast iron body, SS disc & stem and Buna-N or EPDM seat.  The 2" through 6" sizes have lever operators and the larger sizes use a gear operator.

 

The quick-opening cover design is hinged and does not require a cover lift, so in some cases this ends-up being both more convenient and less expensive.

 

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.

 

Since this is a custom fabricated design, we can offer different features, higher pressure designs and larger sizes.  Please use our inquiry form for sizes not shown below.  The standard lead time for custom fabricated model 950 duplex strainers is about 12 weeks ARO.
