Corrosion Control

CORROSION CONTROL

Corrosion Control Programs

They allow the operator to keep the internal, external and atmospheric corrosion threat under control within the desired levels.

The development of these control programs includes the identification of potential threats to the system and the definition of a plan to assess, mitigate and monitor them:

• System and environment assessment.
• Identification of potential corrosion mechanisms and critical areas.
• Development of inspection, mitigation and monitoring programs.
• Procedure development.

CORROSION CONTROL

ECDA / ICDA / CDA Direct Assessments

ECDA/ICDA: The inspection methodology for pipelines that are not piggable for ILI or are strategically complex to assess by hydrostatic testing.

CDA: Confirmatory Direct Assessment to verify the reinspection intervals defined by ILI/HT/DA.

• Identification of critical areas.
• Determination of remaining life and reinspection intervals.
• Selection of optimal monitoring locations.
• Sensitivity analysis.

Developed under strict NACE standards and international best practices.

CORROSION CONTROL

Chemical Treatment Selection

Appropriate chemical treatment translates into greater efficiency, lower costs and less environmental impact.

Selection of the optimal treatment program based on the desired protection objective, performance and costs.

• Biocide evaluation using the "Time-Kill" method.
• Inhibitor evaluation using polarization resistance, Tafel polarization and faradaic impedance methods.
• Compatibility evaluation of different chemicals.

CORROSION CONTROL

Microbiologically Influenced Corrosion Studies - MIC

Microbiologically influenced corrosion can drastically reduce the service life of a component.

MedeaTec offers a variety of services related to the detection, control and mitigation of the microbiologically influenced corrosion mechanism:

• Field and laboratory testing.
• Coupon and bioprobe analysis.
• Biofilm development and evaluation.
• Corrosion rate determination.
• Development of mitigation and monitoring programs.
• Biocide selection.

CORROSION CONTROL

Failure Analysis

Knowing the causes of a corrosion failure makes it possible to design specific strategies to mitigate or monitor them.

Joint evaluation of the evidence and the factors involved in the occurrence of the corrosion mechanism:

• Evaluation of the system and operating conditions.
• Laboratory evaluation of corrosion products: SEM, EDAX, XRD.
• Evaluation of material properties.
• Visual and microscopic inspection of attack morphology.
• Definition of recommended mitigation and monitoring methodologies.
