    The Accuracy 12" Galvanized Spiral Spring for Holiday Detectors is an accessory designed for discontinuity inspection of coatings applied to larger-diameter pipelines, tanks and other cylindrical or curved surfaces.

    Its spiral design follows the contour of the surface during inspection, helping maintain continuous electrode contact with the coating and supporting the detection of pinholes, pores, holidays and other discontinuities.

    With a nominal diameter of 12", it is particularly suitable for larger components, providing appropriate coverage during high-voltage dry-type Holiday testing.

  • Function Details

    FUNCTION DETAILS

    12" Nominal Diameter
    Sized for inspection of larger-diameter pipelines and cylindrical surfaces compatible with 12-inch spiral spring electrodes.

    Greater Inspection Coverage
    The larger diameter makes the electrode suitable for larger components and surfaces, matching the geometry of the area being inspected.

    Spiral Design
    The spring geometry allows the electrode to follow the contour of curved and cylindrical surfaces during inspection.

    Galvanized Construction
    Features a galvanized finish suitable for professional use as an electrode during dry-type Holiday inspection procedures.

    Discontinuity Detection
    Helps identify pinholes, pores, defects and other discontinuities that may compromise the integrity of protective coatings.

    Versatile Geometry Inspection
    Suitable for pipelines, tanks and other coated cylindrical or curved components where improved contact around the surface contour is required.

    Replacement Accessory
    Can be used as a replacement electrode on compatible Holiday Detectors when a 12" spiral spring is required.
