4" Spiral Spring Electrode for Holiday Detector | Accuracy

TUTORIALS

The Accuracy 4" Galvanized Spiral Spring for Holiday Detectors is an accessory designed for discontinuity inspection of coatings applied to pipelines, fittings and other cylindrical or curved surfaces.

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

With a nominal diameter of 4", it is particularly suitable for smaller-diameter components and geometries where flat electrodes may not provide adequate contact with the entire inspection area.

FUNCTION DETAILS

4" Nominal Diameter
Sized for inspecting cylindrical surfaces and pipelines compatible with 4-inch spiral spring electrodes.

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

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

Discontinuity Detection
Helps identify pinholes, pores, defects and other discontinuities that may compromise coating integrity.

Complex Geometry Inspection
Suitable for pipelines, fittings, cylindrical components and other areas where improved contact around the surface contour is required.

Replacement Accessory
Can be used as a replacement electrode on compatible Holiday Detectors when a 4" spiral spring is required.

APPLICATIONS

Holiday inspection of coated pipelines;
Detection of pinholes, pores and coating defects;
Inspection of cylindrical and curved surfaces;
Inspection of fittings and smaller-diameter components;
Quality control of paint and protective coating systems;
High-voltage dry-type Holiday inspection;
Replacement of spiral electrodes on compatible equipment.

Recommended for coating inspectors, quality-control professionals, maintenance teams, service providers and industries performing continuity inspections on coatings applied to pipelines and cylindrical components.

DOCUMENTS

Refer to the technical documentation for the Holiday Detector being used and the applicable inspection procedure to verify electrode compatibility, select the appropriate test voltage and perform the inspection according to the coating and surface geometry.
