Installing the Test Station

Complete the following steps to install the Triton coupon test station.

  1. Expose the buried pipe or structure that will be tested.

  2. Attach the included structure connections (No. 6 AWG Structure 1 and No.10 AWG Structure 2) to the pipe or structure using either exothermic welding or a pin-brazing process.

  3. Remove the plastic packaging from the coupon assembly.

  4. Collect the following information before continuing with the coupon installation:

    1. GPS coordinates

    2. Location name

    3. Pipeline mile post

    4. Backfill type

    5. Installer's name

    6. Installer's NACE CP certificate number

    7. Triton serial number (found on the shipping certificate)

    8. Buried reference cell potential compared to a freshly prepared portable reference cell at the surface

    Refer to Recordkeeping Logs for a form that can be used to record the coupon per-installation data.

  5. Bury the coupon assembly adjacent to the pipe or structure. The coupon assembly must be installed in the following manner:

    1. In a vertical position

    2. 6" to 12" away from the pipe/structure

    3. With the mid-point of the coupon reference cell at a depth relative to the pipe's 5 or 7 o'clock position

  6. Backfill around the coupon assembly with well-compacted native backfill material to ensure accurate measurements.

  7. Set test station where desired; trenching to accommodate lead wires as needed.

  8. After a 60-day polarization period, remove the black plastic shock guard from the test station head and connect the Structure 1 terminal lead to the upper switch terminal. Replace the shock guard when finished. Refer to Testing the Triton Coupon Test Station for instructions on taking measurements from the seasoned coupon.

  9. OPTIONAL: A zinc anode may be installed in association with an induced AC and lightning mitigation system. If used, the zinc anode should be installed on the opposite side of the pipe, away from the buried coupon. Connect the zinc anode to the test head by threading the wire through the cable connection terminal and tightening the holding screw.
