Protect Your Underground Propane Tank: Cathodic Protection Testing

As part of Sharp Energy’s ongoing commitment to safety and compliance, our Company offers free cathodic protection (CP) testing as part of our ongoing and routine service.

What is Cathodic Protection Testing and Why is it Important?

CP testing is a safety measure that helps prevent corrosion on steel propane tanks buried underground. It works by using a small component called an anode, which corrodes in place of the tank—extending its life and maintaining safety.

How Does Cathodic Protection Work for Propane Tanks?

Underground propane tanks can rust because they are always in contact with soil and moisture. Cathodic protection helps prevent this by using:

Sacrificial Anodes: Magnesium anodes are commonly used for propane tanks. They rust over time, protecting the tank from rust.

Impressed Current Systems: For bigger propane storage areas, these systems provide more consistent protection.

How Does Sharp Energy Test Cathodic Protection?

Testing is important to make sure the CP system is working well. National safety codes require periodic protection testing. These tests must be completed within 12 months of tank installation and repeated every three years thereafter.

A trained technician will use specialized equipment to verify that your tank’s protection system is functioning as intended.

This process is non-invasive and typically takes less than 30 minutes.  If your system fails the test, corrective action will be discussed to keep your system safe and compliant.

Cathodic protection is an important way to prevent rust in propane tanks. By understanding how it works and regularly testing the system, we can ensure our tanks stay safe and last longer.
