Ask a Question

  • Are PCWI wire brushes interchangeable or compatible with competitive detectors and vice-versa?

    Yes, with suitable adaptors, which PCWI can manufacture to suit.

  • Will wire brush electrodes ensure good inspection even in corners and around irregular shapes where pinholes or bare spots (holidays) are likely to occur?

    Yes! PCWI Detectors can accommodate a complete range of brushes (see Brochure for illustrations).

  • The PCWI website shows maximum internal and external pipe-brushes at 20" (500mm). Can brushes of greater diameter be provided to complement the Detector?

    Brushes more than 20” (500mm) are large and difficult to handle. However, special large brushes can be made to order. Note: All coil sizes can be used in place of brushes where specification allows. Pipe joints and longitudinal welds should be tested with a brush.

  • Under what conditions are Carbon filled silicone-rubber brush electrodes of advantage?

    These can provide longer life but may require the application of higher voltages. They do not lay flat, and the welded areas should be tested with a brass brush. They should not be used on heavily corroded surfaces and textured coatings.
