Application:

1. External areas of steel pipe, especially in difficult environment such as below grade in rocky and mountainous terrain thawed zones in permafrost, etc.

2. Interior bottom of oil storage tanks.

3. Interstitial spaces between old, corroded and new storage tank bottoms.

4. In the limited space between inner and outer casings of wells of various kinds.

5. For grounding steel tower footings of overhead power systems.

6. To provide cathodic protection as well as to dissipate induced A.C.current on coated steel pipe.

7. For personnel safety, as well as corrosion protection. To ground valves and test stations of pipe lines which are subject to induced A.C.current and fault currents.
