Magnaflux SKL-SP2 Dye Penetrant
Magnaflux SKL-SP2 is a professional solvent-removable visible red dye penetrant designed for reliable detection of surface-breaking defects during non-destructive testing (NDT). Offering excellent penetrating characteristics, vivid red indications and ISO 3452 Sensitivity Level 2, it provides a straightforward and dependable solution for weld inspection, preventative maintenance and quality control.
Suitable for inspecting welds, castings, forgings, pressure vessels, tubular products and general metalwork, Magnaflux SKL-SP2 uses optimised capillary action to penetrate fine surface discontinuities that may otherwise be difficult to identify.
Unlike fluorescent penetrant systems, Magnaflux SKL-SP2 works under visible light, removing the need for UV inspection equipment or darkened inspection areas.
Reliable Visible Dye Penetrant Testing
Detecting cracks and other surface-breaking discontinuities is essential when assessing the quality and integrity of fabricated or manufactured components.
Magnaflux SKL-SP2 uses a highly visible red dye combined with excellent surface wetting and capillary action. The penetrant enters defects that are open to the surface before excess material is removed and a suitable developer is applied.
The result is a clear, high-contrast indication that helps trained inspectors identify potential defects quickly and effectively.
Key Features of Magnaflux SKL-SP2
- ISO 3452 Sensitivity Level 2 – Provides high-performance sensitivity for professional penetrant inspection applications.
- Vivid Red Visible Dye – Produces strong, high-contrast red indications that are easy to inspect under suitable visible lighting.
- Solvent Removable – Excess penetrant can be removed without requiring a water wash, making the system particularly convenient for field inspections and maintenance work.
- Type 2 Visible Penetrant – Designed for visible dye penetrant testing without requiring ultraviolet inspection equipment.
- Methods B, C & D – The SKL-SP2 is classified for Type 2, Methods B, C and D penetrant testing.
- Excellent Surface Wetting – Quickly covers the inspection surface, supporting consistent penetrant application.
- Optimised Capillary Action – Excellent penetrating characteristics allow the product to enter fine discontinuities open to the surface.
- Low Odour – Formulated with low odour to improve usability during professional inspection work.
- NDT Specification Compliant – Designed to meet demanding NDT requirements for professional industrial applications.
What Defects Can Magnaflux SKL-SP2 Detect?
The Magnaflux SKL-SP2 is designed to reveal discontinuities that are open to the surface.
Depending on the component and inspection procedure, these can include:
- Cracks
- Weld porosity
- Leaks
- Inclusions
- Flux inclusions
- Incomplete weld penetration
- Incomplete weld fusion
- Undercutting
- Other relevant surface-breaking discontinuities
This makes the penetrant particularly useful as part of weld quality inspection and preventative maintenance programmes.
Ideal for Weld Inspection
One of the most common applications for Magnaflux SKL-SP2 is visible dye penetrant inspection of welds.
Surface-breaking cracks, porosity and certain weld discontinuities can compromise the quality of fabricated components. Penetrant testing provides a practical NDT method for identifying relevant surface defects without damaging the component being inspected.
The vivid red indications produced by SKL-SP2 make inspection straightforward when used as part of the appropriate penetrant testing procedure.
Simple Three-Step NDT Inspection System
The Magnaflux SKL-SP2 can form part of a straightforward three-stage visible penetrant inspection process.
1. Clean the Surface
The component should first be thoroughly cleaned to remove oil, grease, dirt and other contamination that could prevent the penetrant from entering surface discontinuities.
Magnaflux recommends its SKC-S Cleaner/Remover as a compatible cleaning product.
2. Apply Magnaflux SKL-SP2
Apply the visible red penetrant across the inspection area and allow the appropriate dwell time in accordance with the applicable inspection procedure.
After penetration, remove the excess penetrant from the surface using the specified method.
3. Apply Developer & Inspect
A suitable developer such as Magnaflux SKD-S2 can then be applied. The developer draws penetrant from discontinuities to create clear red indications against a contrasting background.
Inspection should always be carried out by appropriately trained personnel and in accordance with the applicable NDT procedure and standard.
