Corrosion Services

Trident offers in-depth corrosion control and cathodic protection solutions for exposed, buried, or submerged structures. We have a diverse team of engineers, technicians, and inspectors with different levels of and NACE International and other certifications in cathodic protection, coatings, corrosion, and non-destructive examinations. With our expert knowledge base, we are easily able to provide turnkey project solutions from start to finish: design, materials, installation, final testing, and report writing. We will investigate corroded or failed structures, thoroughly examine pipelines to determine viable cathodic protection options, test for Electrical Continuity, Current Requirement, and Video Probe, as required. Most importantly, we will consider all options for Optimum Corrosion Control and Protection Methodology and Technique.
