NACE Exercise: Corrosion in Pipelines
Scenario: A company is planning to install a new pipeline to transport natural gas. The pipeline will be located in a coastal environment with high humidity and exposure to salt spray.
Task: Identify three potential corrosion risks for the pipeline in this environment and recommend NACE standards that can help mitigate those risks.
Exercice Correction
**Potential Corrosion Risks:**
- **Atmospheric Corrosion:** The high humidity and salt spray can cause atmospheric corrosion of the pipeline's exterior, leading to pitting and weakening of the metal.
- **Electrochemical Corrosion:** The presence of saltwater can create an electrolyte, leading to electrochemical corrosion, which can rapidly degrade the pipeline material.
- **Soil Corrosion:** If the pipeline is buried, the soil conditions may also contribute to corrosion, especially if there are corrosive elements present in the soil.
**NACE Standards for Mitigation:**
- **NACE SP0169:** This standard covers external corrosion and erosion of pipelines and provides guidance on inspection, testing, and repair techniques to minimize the risk of pipeline failure due to atmospheric corrosion.
- **NACE TM0168:** This standard addresses the internal corrosion and erosion of pipelines and provides guidelines for selecting materials, coatings, and inhibitors to protect pipelines from the corrosive effects of transported fluids.
- **NACE SP0178:** This standard provides guidelines for the selection and application of coatings for underground pipelines, which can help mitigate soil corrosion.
By following these NACE standards and implementing appropriate mitigation strategies, the company can significantly reduce the risk of corrosion and ensure the long-term reliability of the pipeline.
