Cathodic Protection Support
For buried carbon steel pipelines, we can support the installation of cathodic protection systems to help prevent external corrosion and extend the service life of underground steel pipework.
This can include sacrificial anodes, test posts, insulating joints, bonding cables, reference electrodes and monitoring points installed in line with project requirements and specialist design specifications.
