Preserving AgingInfrastructure
Corrosion Integrity is a design-build corrosion engineering firm. We survey, design and install the cathodic protection that keeps pipelines, storage tanks and concrete infrastructure in service — and we run the non-destructive testing that proves it is fit for service.
Fig. 2 — Storage tanks
Same principle, inside the tank.
On a water storage tank the electrolyte is the water itself. Titanium wire anodes hang from the roof on insulated suspension leads, current spreads through the column onto the shell and floor, and a permanent reference cell reports what the steel is actually seeing — without draining the tank to find out.
Fit for service
An asset is either fit for service, or it is on a clock. We tell you which.
Corrosion Integrity evaluates infrastructure to determine whether the asset is fit for service, what its remaining useful life is, and whether it can continue to operate safely. Every answer comes from measurement — soil resistivity, structure-to-soil potential, wall thickness, coating adhesion — not from inspection by eye.

Capabilities
Engineer it, assess it, build it — under one point of contact.
Design-build means the engineer who specifies the system is accountable for the crew that installs it. One contact owns the schedule, the budget and the deliverables.

Inspection & NDT
Twelve ways to find metal loss before it finds you.
Our engineers and technicians run these methods in-house, each assigned to a project by forensic specialty. Select a method for what it detects and where we apply it.
Ultrasonic thickness
It is estimated that more than $30 billion in corrosion damage occurs in water and wastewater handling systems every year.
Pipelines, storage tanks and treatment plants carry most of it. Cathodic protection, correctly designed and actually monitored, is the cheapest line item on the ledger — and the one most often skipped.
Talk through your assetThe criterion
Minus 850 millivolts is the line.
Cathodic protection is judged against a number, not an opinion. Drag the potential and watch where the steel sits.

- Cu / CuSO4 (CSE)
- Criterion
- −850 mV, IR-free
- Measured
- Instant-off or coupon
Illustrative only — a real assessment needs an IR-free potential and wall thickness data.
Reference cellsReference Cell — Tanks
Permanent cell for structure-to-electrolyte potential monitoring inside storage tanks and clarifiers.
AnodesMag Rod Anode
Magnesium rod for galvanic systems — tank interiors, small structures and retrofit protection.
AnodesCanistered Wire Anode
Canistered wire anode for deep well and distributed ground beds where soil conditions demand depth.
Reference cellsReference Electrode — Underground
Buried permanent electrode for pipeline potential monitoring and remote monitoring unit inputs.
Power & controlPV DC Current Controller
Solar-driven current control for impressed current systems where grid power is not available.
Tank hardwareGrommet
Sealed cable penetration for tank roofs and hand holes.
Test stationsPhenolic Test Board
Anode current testing and shunt terminations — the point where the system gets measured.
Test stationsSacrificial Test Station
Flush or above-grade station for potential and current testing, opening for access to the terminations.
Safety & training
Our foundation is safety. Our people are certified to prove it.
We invest in employee development and in the reporting culture that keeps hazards visible before they become incidents.
Built on dedication to safety
Corrosion Integrity's success and foundation is built on our dedication to safety. Crews carry current certifications, and every project runs safety observation reporting and hazard identification.
Classes & certifications
API RP 578 — Material Verification Program
API 578 gives guidelines for a Material Verification Program (MVP) to confirm the correct chemical composition of alloy materials in new and existing process piping systems across oil, gas and petrochemical service.
- Purpose — establish a quality assurance system for material verification, preventing wrong material installation that leads to accelerated corrosion or component failure.
- Scope — ferrous and nonferrous alloy materials in new and existing process piping systems and equipment.
