Cathodic protection coupons are a simple, size-specific piece of metal with one or more wires attached and are used for evaluating corrosion control or cathodic protection systems protecting a structure, typically a steel pipeline. These measurements include:
Native or unprotected structure-to-soil potentials
Structure-to-soil potentials with the CP system energized
Structure-to-soil potentials with the CP system interrupted
To emulate an “OFF” structure-to-soil potential without interrupting CP current, typically referred to as a “Coupon Interrupt” reading
For magnitude measurements of AC current density on a structure with known inducedAC issues
Cyclone-100 Coupon Details
The "Cyclone-100" steel C.P. coupon is a 100 cm2 "barrel" or cylindrical coupon common in C.P. testing. The larger surface area of the coupon may provide better coupon-to-soil contact upon burial, which is an important consideration for testing.
The coupon is mounted inside a durable PVC housing and the Cyclone-100 is provided with a dual length of #12 AWG stranded copper cable with RHH/RHW direct burial insulation, typically green in color.
Coupon Ordering Information
Specify the Cyclone-100 steel coupon
Choose a cable length of 25, 50, 75 or 100 feet. (Note that a dual cable is standard for this coupon)
Select a cable insulation color (green is the Farwest standard) such as white, blue, orange, etc.
