Pipeline Corrosion Survey Services

Protect Your Pipeline with Expert Assessments

Corrosion is a silent but serious threat to the health of any pipeline network. Over time, it can weaken the structural integrity of pipelines, leading to leaks, failures, and costly repairs. Left unchecked, corrosion endangers the pipeline's safety and functionality and can result in significant financial and environmental consequences.

At Azuria, we offer comprehensive corrosion surveys, also known as corrosion protection surveys, to safeguard your pipeline network. Our expert assessments help you determine the overall status of your infrastructure. By identifying key areas at risk of corrosion, our specialists can propose targeted solutions to strengthen and protect your pipelines, extending their lifespan and preventing future issues. Our corrosion surveys also provide the valuable data you need to maintain compliance with industry regulations.

• LiveLine™ provides real-time visualization and streaming analytics for important points on the pipeline. With alerts and notifications, you are automatically and continuously informed on key metrics at each GIS location.
• ScanLine™ is an interactive charting and analytical tool for viewing current and historical close interval survey data at various points along your pipeline segment.

Threat Assessment

To start protecting your infrastructure from corrosion, our experts conduct a threat assessment, identifying the types of possible threats to your pipeline system. We offer data analysis, management, and engineering assessments to help you identify and rank the various threats to the integrity of your pipeline network. For over 50 years, we’ve been performing pipeline surveys with various advanced techniques, including:

• Close Interval Pipe-to-Soil Surveys (CIS)
• DC Voltage Gradient (DCVG) and AC Voltage Gradient (ACVG) Surveys
• Electromagnetic and Continuous Soil Resistivity Surveys
• Sub-Meter GPS Locating Depth-of-Cover
• Linear Polarization Resistance Corrosion Rate Measurements
• Stress Corrosion Cracking (SCC) Investigations

Pipelines located at water crossings face unique challenges, which is why Azuria offers water crossing external corrosion surveys. These surveys are an effective tool to assess pipeline integrity threats, measure levels of corrosion protection and compliance, and enable appropriate remediation to ensure safe and reliable operation. We also have extensive experience with the remediation of cased pipeline crossings, inspecting both new construction and maintenance work. Our technicians can protect your assets by being on site as your representative to ensure that all companies and contractors follow crossing and proximity agreements and correct ground disturbance procedures.

Baseline Assessment

A baseline assessment is essential for measuring the baseline operating conditions of your pipeline network. This data can help you identify the ideal operating conditions of infrastructure while mitigating issues that can damage pipe coating and expose pipes to external corrosion. Azuria uses three primary types of surveys to inspect your infrastructure:

• External Corrosion Direct Assessments (ECDA): The external corrosion direct assessment is a structured process used to assess and manage the external corrosion threat to pipeline systems. ECDA is part of our overall integrity management program for pipelines and helps us identify, monitor, and mitigate corrosion in pipelines that cannot be inspected using traditional in-line inspection tools. Through direct examination, indirect examination, and ACCA surveys, Azuria can help you proactively identify and mitigate corrosion before it becomes a significant concern.
• Internal Corrosion Direct Assessments (ICDA): Azuria also boasts a team of internal corrosion experts that provide comprehensive solutions for internal pipeline integrity. These services cover initial corrosion assessment and testing, design, and planning the mitigation programs and measurement of the efficacy of corrosion control efforts. ICDA helps identify maximum risk locations through ICDA process optimization, corrosivity predictions, MIC testing, and corrosion monitoring.
• Stress Corrosion Cracking Direct Assessments (SCCDA): Stress corrosion cracking (SCC) is an integrity threat for many pipeline operators. Azuria utilizes direct assessment methodologies to complete SCCDAs on both near-neutral-pH and high-pH stress corrosion cracking.
• Additional In-Line Inspection Services: Azuria offers a wide range of in-line inspection services, including tool selection, program implementation, aboveground market (AGM) placement and documentation, inspection monitoring and analysis, and rehabilitation programs.

Remediation

With data from both the threat and baseline surveys, Azuria’s engineers provide informed recommendations to protect and strengthen existing pipelines. Our services help operators select the best locations and methods for pipeline integrity remediation, whether through corrosion protection systems, AC interference mitigation, or other Azuria pipeline rehabilitation methods.

Mitigation and Prevention

To aid our customers with the prevention and mitigation of pipeline integrity threats, Azuria offers pipeline locating and marking as well as ongoing GIS services, ensuring your pipeline location is known to all stakeholders adjacent to the right-of-way. Our continuous GIS services also help you pick ideal locations for future pipeline projects based on corrosivity and integrity.

Azuria can also design and install comprehensive AC mitigation systems. Whether we’re working with the owner on an existing pipeline system or with a contractor on a new pipeline installation, we have the technical and project management capabilities to staff and equip multiple projects of various sizes.

Continuous Evaluation and Assessment

Maintaining the integrity of your pipeline infrastructure requires more than just occasional checks. Regular corrosion surveys are crucial for staying ahead of potential corrosion issues. By conducting continuous assessments, you ensure that your pipelines remain corrosion-free and fully operational. These ongoing surveys provide the vital data needed to effectively plan and execute maintenance, allowing for timely interventions that strengthen and enhance any areas showing signs of wear.

Frequently Asked Questions About Corrosion Surveys

Have more questions about our corrosion surveys? Explore these common questions from operators like you or contact our team to discuss your needs.

Can Azuria help me plan my pipeline infrastructure project?

• Yes! Through our advanced survey and testing methods, we can help you identify the best locations in your pipeline network to focus your corrosion control efforts.

When should I start corrosion surveys for my pipeline network?

• Corrosion surveys should ideally begin as soon as your pipeline network is operational. Early assessments help establish a baseline for your infrastructure condition and identify any initial signs of corrosion. Starting early also allows you to implement protective measures right from the beginning, significantly reducing the risk of costly repairs and downtime later.

• How long does a typical survey take?

  A corrosion survey's duration varies depending on the length and complexity of your pipeline network and the specific survey techniques used. On average, a typical survey may take anywhere from a few days to a couple of weeks to complete. The process includes both indirect inspections and direct examinations, followed by data analysis and reporting.

How often should I complete a corrosion survey?

• The frequency of corrosion surveys depends on various factors, including the age of the pipeline, its operating conditions, and the results of previous assessments. However, it is recommended to conduct corrosion surveys at least once every three to five years. For pipelines in harsh environments or with a history of corrosion issues, more frequent surveys may be necessary.

What sort of pipes are ideal candidates for corrosion protection?

• Corrosion protection is particularly effective for metal pipelines, especially those made of steel or iron, which are prone to corrosion when buried underground or submerged in water. Pipes in corrosive environments, such as those exposed to saltwater, acidic soils, or high moisture levels, are ideal candidates for corrosion protection.

How do corrosion surveys keep my pipeline infrastructure compliant?

• By regularly assessing the condition of your pipelines and addressing any issues, you ensure that your infrastructure remains compliant with regulatory requirements. Azuria surveys provide the documentation and data needed to demonstrate compliance, avoiding potential fines and legal issues while ensuring your pipeline network is safe and reliable.
