Flathead 1, 1 cm2 Steel Coupon for Cathodic Protection by Farwest Corrosion
An Industry Standard. Available with Single or Dual Test Lead Cables
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 measurments includes:
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.
Use as an isolated coupon to evaluate native or unprotected potentials.
Flathead-1 Coupon
The "Flathead-1" steel coupon is a 1 cm2 coupon made from 1018 alloy steel. The steel coupon is flush mounted inside a durable PVC housing. This coupon includes a specified length of #12 AWG stranded copper cable with RHH/RHW direct burial insulation, typically green in color.
Coupon Ordering Information
Specify the Flathead-1 steel coupon
Select the number of cable lead wires, 1 or 2, for the 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.
