Monel 400 Basket Strainers

Falcon Monel Basket Strainers: Industrial Overview

Falcon Monel basket strainers are specialized filtration components engineered for highly corrosive environments. Monel (typically Alloy 400 or K-500) is a nickel-copper alloy that provides exceptional resistance to seawater, hydrofluoric acid, sulfuric acid, and alkalis, making these strainers essential for offshore drilling and chemical processing.

1. Design & Engineering

The design process focuses on fluid dynamics and pressure vessel integrity.

• Standards: Engineered to international standards like ASME B16.34 (valves) and ASME Section VIII (pressure vessels).

• Flow Optimization: Internal geometry is designed to minimize pressure drop ($\Delta P$) while maximizing the filtration surface area of the basket.

• Customization: Designs include "Dished End" covers for high-pressure stability and various nozzle configurations (Flanged, Threaded, or Socket Weld) to meet specific piping requirements.

2. Manufacturing & Fabrication

Fabrication involves specialized handling of Monel to prevent contamination and ensure structural strength.

• Welding: Utilizing TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding with specific Monel filler wires. All welders are typically certified to ASME Section IX.

• Body Construction: Can be cast or fabricated from Monel plates. Fabricated units allow for custom heights and "off-set" nozzle designs.

• The Basket: The "heart" of the strainer is fabricated from perforated Monel sheet, often lined with a fine Monel mesh for high-precision filtration.

3. Quality Assurance (QA)

Quality control is rigorous to meet the safety demands of the Oil & Gas sector.

• Material Traceability: Every component comes with MTCs (Material Test Certificates) per EN 10204 3.1, ensuring the chemical composition is true Monel.

• Dimensional Check: Verifying flange thickness, face-to-face dimensions, and nozzle alignments against the approved GA (General Arrangement) drawing.

4. Testing Protocols

Before shipment, the strainer undergoes a series of Non-Destructive Testing (NDT) and pressure tests:

• Hydrostatic Testing: The body is tested at 1.5 times the design pressure to ensure there are no leaks or structural deformities.

• Pneumatic Testing: Often performed at lower pressures to check for minute air leaks in seals and gaskets.

• Dye Penetrant Test (DPT): Applied to weld joints to detect surface cracks that aren't visible to the naked eye.

• Positive Material Identification (PMI): A final X-ray fluorescence check to confirm the alloy grade is correct before the nameplate is attached.
