MATCO offers a wide array of services to control corrosion and protect aging assets including poles, latticed towers, grillage, anchor rods, substation equipment, pipeline and more.  One of the best ways to protect assets exposed to corrosive soils or moisture is through the use of cathodic protection.  Cathodic protection effectively protects underground or submerged metallic structures through the use of a negative potential applied by an external source to the structure. Commonly, once the structure has been made sufficiently negative, environmental corrosion (soil or moisture) is resisted. The method is typically applied to iron or steel structures such as underground pipelines, storage tanks, the interior of water storage tanks, ocean pilings, and electrical transmission poles, latticed towers, grillage, anchor rods, and substation equipment. Buried steel structures will revert back to their natural state as an iron oxide without proper intervention.

MATCO has obtained a position of considerable prominence in the cathodic-protection field. As evidence of that, MATCO was hired to provide the entire gamut of CP services for the major liquefied-natural-gas (LNG) terminal in the United States where LNG from Algeria and other offshore sources in unloaded. The facility includes a mile-long submarine steel tunnel in which the pipelines and service utilities are located, all of the mooring pilings, the underground pipelines in the tanks farm on shore and other ancillary facilities.

On a more routine basis, MATCO provides CP services for systems from ones as small as an individual gasoline station tank system to major pipelines of many kinds. Contact us to find out how we can help to solve your CP problems.

Cathodic Protection Training

To promote better understanding of cathodic protection and materials performance in different types of environments, MATCO Services, Inc offers many different training and educational seminars.  Seminars can be arranged to be held onsite or at our location for a nominal fee which includes certifications.  During 2000-2005 MATCO has provided many seminars and participated in short courses for clients and associations, such as:  Appalachian Underground Corrosion Short Course (West Virginia); NASA Kennedy Space Center, IBM facilities (New York); Marco Energy Systems (West Virginia); National Association of Corrosion Engineers (NACE, Pittsburgh Chapter); and ASM International (Wisconsin and Pittsburgh).  Currently, we are organizing two seminars one on  Corrosion Engineering and one on Cathodic Protection/Coating for Pipe Line/Tank Corrosion Control.  Those interested in either of these seminars or future seminars should contact Dr. Zee at 800-221-9090.
