One-Minute Overview

Y-pattern strainer that removes debris from water, oil, gas and steam before it reaches pumps and instruments.
Sizes 1/2 to 24 inch, pressure classes 150LB to 2500LB to ASME B16.34.
Perforated stainless screen cleans easily through the angled blow-off branch.
Compact angled body fits tight piping runs where an in-line basket strainer will not.

A durable Y strainer is an in-line strainer with an angled branch that holds a perforated screen. The screen catches weld slag, scale and other debris carried by the medium, while the clean flow continues through the run. Because the branch sits at an angle to the pipeline, the screen comes out for cleaning without breaking the main pipe apart, which is why Y strainers stay on lines that cannot be shut down for long.

Name: Durable Y Strainer
Type: Y Pattern Strainer
Size: 1/2-24 Inch
Class: 150LB-2500LB
Material: WCB, CF8, CF8M
Standard: ASME B16.34, ASME B16.5
Connection: Flanged RF or Threaded
Feature: Perforated stainless screen with blow-off plug

Select the screen by the mesh the downstream equipment can tolerate: coarse screens protect pumps, finer screens suit meters and control valves. Install the strainer with the angled branch pointing downward on horizontal runs so debris settles into the pocket and drains out of the blow-off plug, and give the branch enough clearance to pull the screen. On vertical runs, flow must travel downward. Check the screen after commissioning and again after any work on the line, because that is when most debris arrives.

Maintenance is quick: close the blow-off, crack the screen cover, slide the cartridge out and wash or replace it. Keep a spare screen of the same mesh on the shelf, since a blocked strainer shows up as a pressure drop across the line. Screen mesh, body material and end connection are confirmed per inquiry, and a detailed specification sheet is available on request.

FAQ

Q1. How is the correct screen mesh selected for a given line?

Match the mesh to what the downstream equipment can tolerate, not to what the strainer can catch. Coarse screens around 10 to 40 mesh protect pumps and valves, while meters and control valves ask for 40 to 100 mesh. Too fine a mesh raises pressure drop and blocks quickly, so always confirm the requirement with the equipment maker.

Q2. Which way does the blow-off branch point when I install this thing?

On a horizontal run, point the angled branch downward so debris settles into the pocket and drains out of the blow-off plug. Leave enough room behind the cover to pull the screen straight out. On vertical runs, flow should travel downward. Getting this backwards does not break the valve; it just turns cleaning into a puzzle.

Q3. The pressure drop keeps climbing - is the strainer trying to tell me something?

Yes, and it is being polite about it. A rising differential almost always means the screen is loading up with debris. Close the blow-off, crack the cover, pull the cartridge and wash it. If the drop returns quickly, the line is shedding something upstream and you may need a coarser screen or a second strainer.

Q4. What's the minimum I can order?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Strainers made to your drawing or for a non-standard bolt pattern are quoted individually, because the minimum really depends on the material and the tooling involved.
