Corrosion Services also designs, manufactures and installs solar power systems for remote locations that don’t have access to an electrical power supply.

Any entity that depends on buried, submerged or surface-placed metal as a component of their business operation is a potential customer.

Based in Billings, Mont., the company has approximately 30 employees and works for customers spread out primarily across the Rocky Mountain Region and Pacific Northwest. The company's newest offices include Williston, N.D., and Wamsutter, Wyo.

Many company employees are accredited by the National Association of Corrosion Engineers. NACE accreditation features various levels of certification depending on work experience and amount and type of classroom training. To achieve the certification, employees need to take classroom training plus pass a rigorous examination.

Project Experience

Since the inception of the company, WBI Energy Corrosion Services has installed thousands of cathodic protection systems on a wide variety of above- and below-ground structures throughout the region in a safe and cost-effective manner.

At- and Below-Grade Storage Tanks
Corrosion Services has designed and installed cathodic protection systems for at- and below-grade storage tanks for scores of facilities located throughout the region. These tanks have demonstrated satisfactory levels of performance even under the harshest conditions. Using the Corrosion Services systems, the useful life of the tank can be extended for more than 50 years.

Some pipelines are government mandated to have cathodic protection as a method of corrosion control. Corrosion Services personnel have designed, installed and maintained pipeline protection systems throughout the region since the early 1980s.  Through this practical experience, many different conditions have been encountered and a variety of different cathodic protection installation methods have been utilized.

Well Casing Systems
Corrosion Services technicians have installed literally thousands of cathodic protection systems for well casings on crude oil and natural gas wells, using either conventional AC power or solar power technology.

Municipal Water Supply Systems
Water is a valuable commodity. Corrosion Services personnel have designed and installed cathodic protection systems for water and wastewater systems throughout the region.

Process Plant Cathodic Protection
Corrosion failures can lead to product losses, liability issues and expensive downtime at chemical plants, electric power stations, refineries, and compression facilities.  Corrosion Services personnel have been involved in cathodic protection at these types of facilities for the last two decades and have the safety training allowing them to work in these locations.
