Corrosion Control

CORROSION CONTROL

Corrosion Control Programs

Internal, external and atmospheric corrosion threat within acceptable limits.

The corrosion control programs include the identification of potential threats to the system, and the development of a plan to evaluate, mitigate and monitore each one of them:

• System and enviroment evaluation.
• Potential corrosion mechanisms assessment and critical areas identification.
• Inspection, mitigation and monitoring planing.
• Procedure developement.

CORROSION CONTROL

ECDA / ICDA / CDA Direct Assessment

ECDA/ICDA: The inspection methodology for pipelines not prepared for in-line -inspections and strategically complex to assess by hydraulic test.

CDA: Confirmatory Direct Assessment to verify reinspection periods defined by ILI/PH/DA.

• Critical areas identification.
• Remainig life evaluation and reinspection periods.
• Monitoring site selection.
• Sensitivity analysis.

Developed under strict NACE standards and best international practices.

Chemical Treatment Selection

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

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

• Biodcides evaluation by "Time-Kill" methode.
• Inhibitors evauation by polorization resistanc, Taefel polarization and Faradaic Impedance.
• Chemical compatibility evaluation.

CCORROSION CONTROL

Microbiologically influed corrosion - MIC

The microbiologically influed corrosion can dramatically decrease the life of a component.

Neotica offers a variety of services related to the detection, control and mitigation of the MIC mechanism:

• Field and laboratory tests.
• Coupons and bioprobes analysis.
• Biofilm developement and evaluation.
• Corrosion velocity determination.
• Mitigation and monitoring programs.
• Biocides sleection.

Failure Analysis

The knowledge of the causes that originated a failure allows the design of specific strategies to mitigate or monitor them.

Joint evaluation of the evidence and factors involved in the manifestation of each mechanism:

• System evaluation and operating conditions.
• Corrosion products laboratory analysis SEM, EDAX, DRX.
• Material properties evaluation.
• Visual and microscopic inspection of damage morphology.
• Definition of mitigation and monitoring recommended methodologies.
