Flat Wire Brush Electrodes
Model No. :
Brand : Defelsko
The Flat Wire Brush Electrodes are versatile high-voltage accessories designed for holiday detection across a variety of surfaces, including flat areas, large sections of pipe, and slightly curved structures. Constructed from durable stainless steel, these brushes are engineered to ensure reliable electrical contact with the coated surface, guaranteeing continuity for accurate flaw and pinhole detection in protective coatings.
- Versatile for flat or curved coated surfaces
- Constructed from durable stainless steel wire
- Available in multiple widths up to
− Features
- High-Conductivity Stainless Steel: Made entirely from high-quality stainless steel wire, providing superior electrical conductivity and exceptional resistance to wear and corrosion in demanding industrial environments.
- Flexible Application: The flat brush configuration is ideal for inspecting large, open flat surfaces (like tank floors or plates) as well as the surfaces of large-diameter pipes and vessels where the curvature is minimal.
- Extensive Width Options: Available in a comprehensive range of widths, from a narrow for small areas, up to for maximizing inspection coverage on broad surfaces.
- Threaded Connection: Designed to securely attach to the PosiTest HHD electrode rod via a standard connection, ensuring a stable mechanical and electrical link during the application of high voltage.
- Compatibility with Standards: When used with the PosiTest HHD series, these brushes help ensure that coating inspections meet the surface contact requirements specified by international standards like ASTM and NACE.

FAQs
Which type of surface are Rolling Spring Electrodes designed for?
They are specifically designed for the cylindrical outer surfaces of pipes and tubing, ensuring the electrode maintains full, continuous electrical contact as it rolls.
What material are the Rolling Spring Electrodes made from?
The electrodes are constructed from stainless steel, offering excellent conductivity and resistance to corrosion for reliable performance.
Are custom sizes available for non-standard pipe diameters?
Yes, while a wide range of standard sizes is available ( to ), custom electrode sizes can be ordered upon request to fit unique pipe dimensions.
What accessory is needed to connect the spring to the PosiTest HHD?
A separate accessory, the Spring Connector (HHDCONNECT), is required to securely attach the pre-installed spring couplers on the electrode to the PosiTest HHD or HHD C detector.
How do Rolling Spring Electrodes ensure a complete inspection?
Their design guarantees that the entire circumference of the coated pipe is simultaneously subjected to the high voltage as the electrode is rolled, ensuring surface coverage for flaw detection.
