1.5" FNPT Y Strainer for Steam and Water Systems

This Mueller Steam Specialty Y strainer fits 1.5 inch female NPT piping and handles steam or water up to 480 psi at 100 degrees F. The carbon steel housing is rated Class 600 for demanding industrial service.

Included 304 Stainless Steel Perforated Screen

A 304 stainless steel screen with 0.062 inch perforations comes installed, filtering debris without a separate mesh layer. The 3/4 inch blow-off port allows cleaning without removing the strainer from the line.

30 GPM Flow Factor with 1015 psi Maximum Pressure

The Cv of 30 gpm provides ample capacity for typical 1.5 inch process lines while the 1015 psi maximum pressure rating gives headroom above the 480 psi working limit. Not suited for applications requiring finer mesh filtration or larger pipe diameters.

Questions about this item

How often will the 304 stainless steel screen with 0.062 in perforations need cleaning or replacement?

Cleaning frequency depends on the debris load in the steam or water system; the screen is removable via the 3/4 in blow-off port for routine flushing without disassembly.

What pressure or temperature limit is reached first during continuous operation?

The strainer is rated for 1,480 psi at 100 °F and a maximum of 1,015 psi; sustained steam service will hit the temperature ceiling before the pressure ceiling.

How much heat does the carbon steel body radiate when steam runs through it all day?

The carbon steel housing at Class 600 will approach steam temperature; external insulation is recommended to reduce radiated heat and protect nearby components.
