Inconel 825 Y Strainers

At Falcon, we provide specialized filtration solutions for the most demanding chemical and offshore environments. Our Inconel 825 Y-Strainers are specifically designed to excel in applications involving sulfuric and phosphoric acids, where standard alloys face rapid degradation.

Inconel 825 is a Nickel-Iron-Chromium alloy with added Molybdenum, Copper, and Titanium. This unique "balanced" chemistry provides:

• Sulfuric Acid Protection: The inclusion of Copper makes 825 exceptionally resistant to sulfuric acid across varying concentrations and temperatures.

• Chloride Immunity: High nickel content ensures total resistance to Chloride-Ion Stress Corrosion Cracking (SCC).

• Oxidizing & Reducing Resistance: Unlike many alloys, 825 performs reliably in both oxidizing acids (Nitric) and reducing acids (Phosphoric).

• Weld Stability: Titanium stabilization prevents "sensitization," ensuring the strainer remains corrosion-resistant even after high-temperature welding.

Engineered for high-pressure, mission-critical systems.

• Structural Integrity: The forging process provides a refined grain structure, eliminating internal voids and maximizing fatigue resistance.

• High-Pressure Performance: Best for Class 600, 800, and 1500 systems in oil and gas recovery or chemical reactors.

The industry standard for large-scale flow and moderate pressure.

• Optimized Flow Geometry: The cast Y-pattern minimizes internal turbulence, resulting in a lower pressure drop ($\Delta P$) during operation.

• Economic Value: Offers the same superior chemical resistance as the forged version, providing a cost-effective solution for larger bore sizes (2" to 24").

Falcon ensures full traceability and compliance with these global standards:

Falcon’s Inconel 825 strainers are essential in:

• Chemical Processing: Equipment for acid production, pickling tanks, and agitators.

• Oil & Gas: Protecting wellhead components and pipelines in "sour" ($H_{2}S$) gas environments.

• Pollution Control: Scrubber systems designed for sulfur-containing flue gases.

• Nuclear Fuel Reprocessing: Handling radioactive waste and fuel dissolver systems.

• Marine Engineering: Propeller shafts and seawater piping systems.

• Design Code: ASME B16.34 (Standard for Pressure-Containing Components).

• Pressure Ratings: ANSI Class 150 through Class 1500.

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

• End Connections: Flanged (RF/RTJ), Socket Weld (SW), and NPT Threaded.

Falcon Quality Assurance: Every Inconel 825 Y-Strainer is supplied with a full EN 10204 3.1 Material Test Report (MTR). We ensure that our internal screens (perforated or mesh) are also manufactured from Inconel 825 to prevent any galvanic corrosion within the unit.

Falcon specializes in Inconel 825 Y-Strainers, providing a balanced solution for environments where both oxidizing and reducing acids are present. This Nickel-Iron-Chromium alloy is specifically engineered for superior resistance to Sulfuric and Phosphoric acids, making it a "specialist" for chemical processing and oil recovery.

We offer high-integrity Forged (ASTM B564 N08825) bodies for high-pressure Class 600–1500 systems and Cast (ASTM A494 CU5MCuC) units for optimized flow in Class 150/300. With high nickel content, these strainers are immune to chloride-ion stress corrosion cracking and pitting.
