Corrosion Inhibitor Testing

Corrosion is a natural phenomenon that can be difficult to prevent and control in the Oil and Gas industry. With increasingly harsh operating environments, pressure changes, and flow conditions, pipelines and infrastructure must be protected to ensure they are compliant, safe, and fit-for-purpose.  

Element is the number one provider of Materials Testing, Inspection, and Certification services to the Oil and Gas Upstream sector and a leading international provider to the conventional Fuel and Nuclear Power Generation sector. We have the global reach, expertise and knowledge to help you prevent corrosion in your most critical assets utilizing corrosion inhibitor testing. 

Corrosion inhibitors in the oil & gas industry

Corrosion inhibitors are chemical compounds are typically added to a metal or alloy to mitigate or control corrosion. The correct application of chemical corrosion inhibitors is vital to reduce corrosion and maximize the lifespan of metal applications.

Failures due to general and localized corrosion and under deposit corrosion can lead to impairment of the function of the metal, causing leaks, bursts, and loss of operational performance.

Our corrosion experts make certain that the most suitable combination of corrosion inhibitors are applied, to significantly reduce the rate of corrosion and ensure your pipelines remain protected.

Corrosion inhibitor test methods

Our corrosion inhibitor testing inspects metals, carbon steel, and corrosion-resistant alloys using electrochemical corrosion inhibitor testing methods to simulate a wide range of environments, including sweet (CO2) and sour (H2S) conditions for Oil & Gas applications.

We use Potentiodynamic Polarisation, Linear Polarisation Resistance (LPR), and Electrochemical Impedance Spectroscopy (EIS) test methods according to the most relevant ISO and ASTM standards to evaluate the influence and effectiveness of corrosion inhibitors.  

Facilities and equipment

Element’s state-of-the-art testing laboratories can simulate a wide variety of high-pressure, high-temperature, flow regimes and sweet and sour environmental conditions:

• HPHT dynamic autoclaves
• Flow regimes
• Acid gasses (sweet and sour)
• Electrochemical monitoring systems
• RCE (Rotating cylinder electrode)
• Flow loop (sweet use)

The Element advantage

Our experts have specialist knowledge in corrosion testing, CO2 corrosion, H2S corrosion, and galvanic corrosion testing. With a global network of laboratories, we make certain that fast and accurate results in corrosion inhibitor investigations translate into a real-world asset.
