Super Duplex SS 2507 Y Strainers

To maintain the technical integrity of the Falcon brand, here is the original, comprehensive content for Super Duplex SS2507 Y-Strainers, created specifically for your website.

At Falcon, we deliver engineering excellence for the most corrosive offshore and industrial applications. Our Super Duplex SS2507 Y-Strainers are designed for high-pressure systems where traditional stainless steels fail due to pitting, erosion, or stress corrosion cracking.

SS2507 is a high-alloy Duplex stainless steel with 25% Chromium, 4% Molybdenum, and 7% Nickel. This "Super" chemistry provides:

• Extreme Pitting Resistance: With a PREN (Pitting Resistance Equivalent Number) above 40, it is exceptionally resistant to chloride-ion pitting in warm seawater.

• Dual-Phase Strength: The 50/50 austenite-ferrite microstructure provides double the yield strength of 316L stainless steel, allowing for more robust and high-pressure-rated strainer designs.

• Erosion-Corrosion Resistance: Superior hardness makes it the ideal choice for high-velocity flow containing sand or abrasive particulates.

• Immunity to SCC: Highly resistant to chloride stress corrosion cracking (SCC), even in high-temperature brine environments.

The premium choice for high-pressure offshore instrumentation and manifold systems.

• Refined Grain Structure: Forging ensures a dense, uniform structure required for Class 1500 and 2500 pressure ratings.

• Precision Integrity: Ideal for compact Y-strainer designs used in chemical injection and subsea hydraulic lines.

The industrial standard for large-scale desalination and seawater cooling systems.

• Grade 5A (CE3MN): The primary cast grade utilized by Falcon for large-diameter Y-strainer bodies.

• Flow Optimization: Our cast Y-patterns are precision-engineered to handle high-velocity seawater with minimal pressure drop ($\Delta P$).

Falcon ensures every Super Duplex unit is fully traceable and complies with these global designations:

Falcon’s Super Duplex strainers are indispensable in:

• Desalination Plants: Handling high-pressure brine and intake systems.

• Offshore Oil & Gas: Subsea equipment, firewater systems, and cooling water lines on platforms.

• Reverse Osmosis (RO): Critical high-pressure filtration stages in water treatment.

• Chemical Tankers: Handling aggressive chemical cargoes and seawater ballast.

• Mining: Protecting pumps in acidic and abrasive slurry pipelines.

• Design Code: ASME B16.34 (Valves and Pressure Components).

• Pressure Ratings: ANSI Class 150 through Class 2500.

• Testing: 100% shell and seat pressure testing per API 598.

• End Connections: Flanged (RF/RTJ), Hub-ends, and Buttweld (BW).

Falcon Quality Assurance: Every Super Duplex SS2507 Y-Strainer includes a full EN 10204 3.1 Material Test Report (MTR). We ensure that our internal screens—whether perforated or mesh—are also manufactured from S32750 to prevent any galvanic imbalance within the unit.

Falcon specializes in Super Duplex SS2507 Y-Strainers, the ultimate high-strength solution for chloride-rich marine environments. Offering twice the yield strength of standard stainless steels, these strainers are engineered for extreme durability. With a PREN > 40, SS2507 provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in warm seawater and high-pressure brine.
