CASE STUDY: Corrosion in steel casing for small diameter pipelines

Steel casings for smaller pipelines are generally lighter and easier to handle, but they are often exposed to more challenging environmental conditions. The casing must be thin enough to maintain flexibility yet durable enough to provide reliable protection against external damage. Steel casings buried in soil or submerged in water face heightened risks of corrosion from moisture, chemicals, and electrolytes, which can gradually weaken the material. Additionally, contact with different metals or stray electrical currents can lead to electrolytic corrosion, compromising the integrity of the steel and creating potential failure points. The impact of corrosion in steel casing includes:

• Reduced structural integrity of the casing, making the pipeline more vulnerable to damage.
• Leaks, contamination, or product loss, which can jeopardize both the pipeline's function and the surrounding environment.
• Increased maintenance costs and a shortened operational lifespan for the pipeline.

To mitigate corrosion and protect steel casings, the following preventive measures were considered:

• Use of protective coatings when the carrier pipe is made of plastic, which acts as a barrier against corrosive elements.
• Cathodic protection to prevent corrosion caused by electrochemical reactions between metals.
• Proper installation techniques to avoid exposure to high-risk environments like zones with excessive moisture.
• Routine inspection and monitoring to identify corrosion early and address issues before they cause significant damage.

By implementing these best practices, the durability of steel casings can be enhanced, reducing both the likelihood of failure and the costs associated with maintenance.

In marine and industrial environments, the splash zone presents significant challenges due to ongoing exposure to moisture and corrosive elements. Selecting an appropriate coating for these areas is critical for ensuring long-term protection and adherence to industry standards. Key factors contributing to corrosion in splash zones include:

Oxygen Exposure: Oxygen can facilitate the electrochemical reactions that lead to rust formation on metallic surfaces, increasing corrosion rates. 

Moisture Exposure: Continuous contact with water accelerates the corrosion of underlying materials.

Chemical Attack: Splash zones are frequently subjected to aggressive agents, such as salts and various industrial chemicals, which can compromise the effectiveness of protective coatings.

Physical Wear: Mechanical impacts and abrasion from debris can undermine the integrity of protective layers, increasing the susceptibility to corrosion.

Temperature Fluctuations: Extreme heat can accelerate chemical reactions that lead to degradation, while low temperatures may hinder the adhesion of coatings. 

Failure of protective coatings can result in significant structural degradation, leading to costly repairs and potential safety hazards. To effectively mitigate corrosion risks, it is vital to incorporate robust protective measures from the initial stages of project development and to consistently monitor the condition of the coatings throughout the structure's lifespan. This proactive strategy takes into account multiple factors that influence performance of the coatings.

Corrosion in steel rebars occurs when the protective layer around the rebars in concrete is compromised. Common causes include: 

• Chloride Ingress: Salts from de-icing materials or seawater can penetrate the concrete and disrupt the steel’s protective layer.
• Carbonation: Carbon dioxide reacts with concrete, lowering its pH and weakening the protection around the steel.
• Moisture: Excess moisture within the concrete accelerates the corrosion process.

Corrosion causes the steel to rust and expand, which can lead to cracking and spalling of the concrete. Preventing corrosion involves ensuring that protective measures are integrated into the construction process and maintaining vigilance throughout the structure's lifespan. This includes considering factors that influence the longevity of both the concrete and the steel reinforcement. 

We are excited to support the 63rd Annual Conference of Metallurgists (COM 2024) as one of the organizers of Corrosion and Environmental Degradation of Materials Symposium. 

Scheduled to take place from August 19 to 22, 2024, at the Halifax Convention Center, this prestigious event is hosted by the Metallurgical Society (MetSoc) of the Canadian Institute of Mining, Metallurgy, and Petroleum (CIM). 

Our support in organizing this symposium underscores our commitment to advancing the field of corrosion science and material durability. By backing this significant event, we aim to foster innovative research and develop practical solutions for material degradation and environmental sustainability.

Corrosion Under Insulation (CUI) is a critical issue that occurs when moisture becomes trapped between insulation material and the pipeline surface. Here’s a closer look at the key factors contributing to CUI:

• Moisture Infiltration: Water or condensation within insulation accelerates corrosion.
• Insulation Damage: Compromised insulation allows moisture to contact the pipeline surface.
• Temperature Variations: Fluctuating temperatures can lead to condensation and increase corrosion.

Addressing CUI effectively requires a thorough evaluation of each unique case. While regular inspections, corrosion-resistant coatings, and high-quality insulation materials are common strategies, a tailored approach is essential.
