Cathodic protection for underground storage tank

For UST Owners Allow Southern Cathodic Protection Company to assist you in protecting your investment by preventing leaks and meeting state and federal regulations for underground storage tanks and piping.

Even without the strigent EPA regulations mandating corrosion control on underground storage tanks, a sound leak control program makes economic sense. Southern Cathodic Protection Company provides professional engineering services to assist tank owners in preventing leaks and achieving regulatory compliance.

These services include:

Corrosion Surveys to collect site specific information concerning soil characteristics, resistivity, electrical continuity, stray currents and interference.
Statistical Corrosion Probability (SCP) analysis for evaluating underground storage tank suitability for upgrading with cathodic protection in accordance with ASTM standards.
Testing and Design of tanks and piping, provided by registered Professional Engineers and NACE International Certified Corrosion Specialists, insures optimum corrosion control and operating efficiency.
Cathodic Protection Installations extend the life of both tanks and piping indefinitely. The cathodic protection cost represents a mere fraction of tank replacement costs. Cathodic protection can be applied to old or new tanks without disrupting operations.
Remote Monitoring uses computers and modems to automatically acquire and verify cathodic protection operating data while maintaining required records.
Statistical Inventory Control utilizes daily stick readings to economically meet EPA tank tightness and monthly monitoring requirements.
Environmental Assessment is performed for buyers and sellers to protect against financial liability resulting from contaminated soils.-

PIPELINE ENGINEERING

Cathodic Protection for Pipelines

Southern Cathodic Protection Company (SCPC) has demonstrated experience in virtually all aspects of the pipeline transmission and distribution industry from routine operation and maintenance-related matters to engineering design and construction. The firm has successfully completed a wide variety of projects ranging from relatively small scopes of work through major construction projects. As a result of our 200+ years combined experience in gas and liquid pipeline engineering, SCPC understands the importance of close communication with the client throughout any project we undertake. Our employees are well versed in the regulatory codes affecting the natural gas and liquid pipeline industry, i.e., Title 49 CFR Parts 191, 192, 195 and 199.

SCPC provides a wide range of engineering services to the pipeline industry including many areas of consulting expertise and project management. The following will outline the variety of services available to natural gas and liquid pipeline operators:

Facts About Impressed Current Cathodic Protection (ICCP)

The cathodic protection current of an Impressed Current Cathodic Protection (ICCP) system is obtained from an external source such as the local utility company which can impose a current sufficient to counteract the existing currents of the corrosion cell. The current is "impressed" on the corroding structure through the use of relatively inert anode materials.

Typical Components

Typically an impressed current cathodic protection system for a concrete structure will contain the following components.

DC Power source
Inert anode material
Wiring and conduit
Monitoring devices
The local utility is the most common source of external power for the system. This is of course AC current and must therefore be converted to DC current for use in the CP system. Rectifiers are available in a variety of sizes and types to satisfy the needs of all corrosion prevention situations.

The Anode

Anode material in an ICCP system is a relatively inert material such as catalyzed titanium. By using relatively inert materials, anode consumption is minimized.

The anode is one of the most critical components of the system because it distributes protective current to the reinforcing steel. It is also the location of all anodic reactions in the system and will therefore eventually be consumed. It is desirable to use anode material with a long life expectancy which can be accurately predicted. Catalyzed titanium is such a material.

Selection of catalyzed titanium as the anode material will yield a life expectancy of more than 40 years for existing structures and more than 100 years for new structures.

Maintenance

After installation minimal maintenance is required to insure proper functioning of an ICCP system. This involves visual inspection and periodic monitoring of the voltage and current as well as insuring proper supply of DC current to the anode. During installation of the system it is common practice to imbed silver/silver chloride reference electrodes to facilitate routine monitoring.
