3" DN80 Super Duplex Stainless Steel A995-5A Flanged Y Type Strainer – ANSI Class 150LB

Tengs Valve supplies 3" (DN80) ANSI Class 150LB flanged Y type strainers in super duplex stainless steel A995-5A (UNS S32750 / 2507). This Y strainer is designed for seawater, desalination, offshore and other chloride-containing service where standard SS304 or SS316 would suffer from pitting and stress corrosion cracking. The flanged RF / RTJ connection allows direct installation into ANSI B16.5 pipelines. Screen material is SS316 as standard, with other mesh options available on request. The bolted cover allows the screen to be removed for cleaning without disconnecting the main pipeline.

Why Choose a 3" A995-5A Super Duplex Y Strainer?

Standard stainless steel Y strainers in SS304 or SS316 can suffer from pitting corrosion and chloride stress corrosion cracking in seawater and offshore environments. Super duplex stainless steel A995-5A (UNS S32750 / 2507) offers significantly higher resistance to these failure modes, making it suitable for seawater desalination, offshore platforms, coastal power plants and other chloride-containing service. At 3" (DN80) and ANSI Class 150LB, this strainer fits most common pipeline sizes in these applications. The flanged RF / RTJ connection allows direct installation without adapters, and the bolted cover allows quick screen access for cleaning and maintenance. NACE MR0175 compliance is available on request for sour service.

Applications

• Seawater and desalination systems
• Offshore platforms and marine pipelines
• Coastal power plant cooling water systems
• Chemical plants handling chloride-containing media
• Oil & gas production with corrosive service
• Protection of pumps, valves and meters
