Cyclone 10, 10 cm2 Steel Cylindrical Coupons by Farwest Corrosion

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 induced AC issues
  

Cyclone-10 Coupon Details

The "Cyclone-10" steel C.P. coupon is a 10 cm² "barrel" or cylindrical coupon common in C.P. testing.

The coupon is mounted inside a durable PVC housing and the Cyclone-10 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-10 steel coupon
• Choose a cable length of 25, 50, 75 or 100 feet.
• Select a cable insulation color (green is the Farwest standard) such as white, blue, orange, etc.
