Corrosion control for buried or submerged metals requires a combination of high-quality coatings and cathodic protection. Coatings systems should always be carefully designed, applied and inspected, but they do not defeat corrosion on their own.
Cathodic Protection (CP) Systems
- Design, installation, and testing.
- Designs and specifications for CP systems, based on site-specific testing data.
- Installation of impressed-current CP systems.
- Installation of galvanic anode CP systems.
- AC-induced corrosion studies and mitigation plans.
- Current demand studies.
- Identification of corrosion mechanisms.
- Ground/neutral system interconnection diagnoses.
- Water and wastewater pipelines (Steel, PCCP, RCP, DIP).
- Water and wastewater utility vessels, lines and fittings.
- Water and wastewater treatment plants (digesters, clarifiers, filters)
- Water storage reservoirs
- Fire suppression piping and fittings
