    Q-AMP™ bracelet anodes are a family of products consisting of quadrants of multiple arc segments. Each segment contains cast-in, circumferentially oriented steel cores. Bracelets are assembled with 4, 6 or 8 units depending on pipe diameter. Q-AMP bracelet anodes are superior to both semicircular bracelet assemblies in the larger sizes and multi-segment, external core assemblies because they offer:

    • More accurate sizing over pipe coatings to eliminate gaps that promote excessive wastage of the anode at the inside diameter of the bracelet.
    • Minimal distortion and "locked-in" stress when compared to conventional semi-circular bracelets for pipes of about 20"diameter.

    The maximum arc length of each segment ranges from about 14" to about 27". Each segment contains at least one circumferentially-oriented steel core.
