Cathodic Protection Service[edit]

A cathodic protection service is a type of corrosion protection that is designed to protect pipelines from corrosive elements. The process can be customized to meet the needs of a particular pipeline or facility. A potential survey is required to determine if the pipeline needs protection. Depending on the type of pipeline and its location, a cathodic protection service can be designed and installed for the specific needs of the facility. The process of cathodic protection can be completed on both aboveground and underground storage tanks. Some of the methods used include cleaning, lining, and retrofitting. Some companies offer single-walled tank protection with manholes. Some companies provide turnkey solutions for engineering and installation. Some even provide decommissioning services. These companies have the knowledge and equipment to handle any type of corrosion problem and ensure that their client's assets are protected. Cathodic protection is an important safety precaution for the natural gas and oil industries. In order to properly use cathodic protection systems, operators must measure cathodic protection regularly. The problem is expensive to collect, and measurements are reactive. Without a professional cathodic protection service, problems can go undetected for long periods. In order to ensure the integrity of natural gas pipelines, contact a reputable company that offers cathodic protection services. Impressed current cathodic protection systems are used for larger structures. They consist of anodes connected to a DC power source, often a transformer-rectifier. Alternate power sources may be used if an AC supply cannot be obtained. Common anode shapes include solid and tubular rods. Materials used for anodes include high silicon cast iron, mixed metal oxide, and coated wire. However, the materials used for cathodic protection are not limited to these materials. Sacrificial anodes are metallic anodes that are oxidized before the protected metal. This serves as a barrier between the protected metal and corrosion. To prevent corrosion, companies use corrosion inhibitors to minimize oxidation and slow down corrosion. These chemicals are referred to as cathodic, anodic, and mixed inhibitors. The latter type is most suitable for higher current applications. So, if you are in need of cathodic protection, contact a company that provides this service. There are several types of cathodic protection rectifiers, but the simplest type provides DC power to impress current cathodic protection systems. They are normally installed as part of a larger CP system but can also be installed after installation to address compliance issues. Remote rectifier monitors are a good option for monitoring the CP system from a remote location. Farwest has installed hundreds of rectifiers and RMUs and is experienced in meeting the local electrical code requirements.
