What does the P3 stand for in STI P3?

sti-P3 Means Three Levels of Protection for Your Tank The anodes are made from metals that are more electrically active and, therefore, will corrode preferentially to steel. For an sti-p3 tank, the anodes are zinc or magnesium.

What is a STI P3 tank?

Cathodically protected steel tank sti-P3® double‐wall underground storage tank features a pre‐engineered corrosion protection system that provides ongoing monitoring of corrosion protection. The sti‐P3® system has provided reliable, long‐term performance for over a quarter million steel underground storage tanks.

How do you keep corrosion from buried in a petrol tank?

In most cases, corrosion protection of steel USTs will include the application of cathodic protection (CP). Dielectric coatings with cathodic protection for new steel tanks and installation of cathodic protection on existing steel tanks have been cost-effective methods for corrosion control and leak prevention.

Why is magnesium connected to underground petrol tanks?

In a cathodic protection system designed to prevent steel underground tanks from corroding, a sacrificial anode is a bar of metal, usually made of magnesium or zinc and connected to the metal to be protected.

How big are underground gas tanks?

Burial Depth of Underground Steel Storage Tanks Gas stations were much smaller back then and had fewer dispensers. Typical tank capacity was 8,000 gallons, and orders for tank capacities of 10,000 or 12,000 gallons were made for new, state-of- the-art convenient stores at busy intersections.

How much does a 12000 gallon fuel tank cost?

Do steel tanks corrode?

Corrosion is a deteriorative process that results from chemical or electrochemical reactions between the steel and its environment. Without the proper protection mechanisms in place, steel tanks will naturally corrode in the most vulnerable areas.

How long does an anode bag last in a metal underground tank?

~Without proper protection, a tank is vulnerable to corrosion, which results into a possible leak. ~According to the NFPA 58 LP-GAS codes, this MUST be done in intervals not to exceed 36 months. ~Depending on your soil type, these anode bags could be consumed in as little as 6 years.

How long does gas last in an underground tank?

The key is keeping the fuel cool and keeping the fuel dry. Under ideal conditions, diesel fuel can be stored between six and twelve months. To extend the life past twelve months, even under the best conditions, it needs to be treated with fuel stabilizers and biocides.
