2" A351-CF8M Stainless Steel Flanged Y Type Strainer – ANSI Class 150LB, Bolted Cover, 1/2" NPT Drain Plug

Tengs Valve supplies 2" (DN50) ANSI Class 150LB flanged Y type strainers in A351-CF8M stainless steel (SS316 equivalent). This Y strainer features a bolted cover with a 1/2" NPT drain plug, allowing quick screen access and convenient drainage during maintenance. The flanged RF / RTJ connection fits ANSI B16.5 pipelines. The CF8M body provides better corrosion resistance than CF8/SS304, making it suitable for water, gas, oil, steam and mildly corrosive media. Sizes are available from 1/2" to 36" on request; this page covers the 2" DN50 specification.

Why Choose a 2" A351-CF8M Flanged Y Strainer?

A351-CF8M is the cast equivalent of SS316, offering better corrosion resistance than CF8/SS304, particularly in chloride-containing and mildly corrosive media. At 2" (DN50) and ANSI Class 150LB, this strainer fits common pipeline sizes in water treatment, chemical processing, oil and gas, and power generation. The bolted cover design allows the screen to be removed for cleaning without disconnecting the pipeline. The 1/2" NPT drain plug on the cover allows the strainer body to be drained before maintenance, reducing spillage and improving safety. For sour service, NACE MR0175 compliance is available on request.
