Part Number: 6005-0035

Product Features

  • Can be specifically designed to client specification
  • Various cable lengths available
  • Pipeline Test & Monitoring Coupons

    Test/monitoring coupons are increasingly becoming an essential tool in the monitoring of cathodic protected buried pipelines. Coupons provide a convenient and efficient means of measuring important parameters such as the coupon to soil AC discharge current density or the coupon to soil instant-OFF potential.

    Buckleys are able to provide a variety of specifically designed coupons to meet various pipeline operator requirements, please contact our sales department for advice.

    DC coupons provide the ability to measure an error-free ‘instant-OFF’ pipe to soil potential, to prove the level of cathodic polarisation achieved on the pipeline. They are particularly useful in areas subject to DC stray currents and on all cathodic protection systems where the synchronised interruption of DC current supplies is complex or impractical.

    The coupon consists of a steel plate with an exposed area of 25cm² fitted into a 75mm square housing. The connection between the coupon and the cable is potted to stop the ingress of moisture. Three standard cable lengths are available, 5metres, 10metres and 20metres.


    The standard cable used is 6mm² 6491X Blue on the AC coupons and 10mm² 6491X Blue on the DC coupons, other cable sizes or colours can be supplied.

    Note: Due to ongoing technical developments, all stated information is typical and is subject to change without notice or obligation.
