What is a Pipeline Inspection?
A pipeline inspection is conducted by pipeline engineers as part of overall preventive maintenance to verify the integrity of a pipeline system and reduce the risks of leaks, pressure surges, and corrosion. Pipeline operators should empower frontline workers to perform routine pipeline inspections with mobile-ready tools for triggered alerts to the right people when potential issues arise.
A pipeline inspection checklist is used by pipeline engineers to verify the integrity of a pipeline system and prevent costly shutdowns. Use this checklist to inspect the pipeline’s design, installation, operation, maintenance, and corrosion control procedures, coating and cathodic protection, test stations, remedial measures, and monitoring. With iAuditor temperature and humidity sensors, global pipeline operators can monitor pipelines from the control room and gain real-time and historical information across assets and sites.

A pipeline corrosion inspection report is a comprehensive document used by area managers to anticipate corrosion-related problems and mitigate their consequences, such as disruptions in power, transportation, and infrastructure. Automatically generating and submitting pipeline corrosion inspection reports helps site supervisors control corrosion immediately and minimize costs.
In a report filed by Energy Transfer Partners with the Pipeline and Hazardous Materials Safety Administration last July, corrosion ruptured a 30-inch diameter steel pipe near Missouri Highway 15. The pipeline eventually exploded and incurred a total incident cost of $1.4 million. Global pipeline operators can prevent similar incidents from occurring through corrosion risk management and following the pipeline external corrosion direct assessment methodology developed by the National Association of Corrosion Engineers (NACE International) below:
Step 1: Pre-assessment
Pipeline operators should collect historic and current data such as construction records, operation and maintenance histories, and corrosion control procedures to analyze which indirect inspection tools should be used. Select indirect inspection tools such as close-interval survey (CIS), current voltage gradient (ACDVG/DCVG) survey, and/or AC current attenuation survey based on the ability to detect corrosion activity.
Step 2: Indirect Inspection
This step covers above-ground inspections and/or inspection from the ground surface to determine the severity of coating faults and other areas where corrosion activity may have occurred or may be occurring. Use two or more indirect inspection tools to provide improved detection reliability, especially for identifying atmospheric corrosion.
Step 3: Direct Examination
Integrate the pre-assessment data with the indirect inspection results to determine the segments for pipe surface evaluations and excavations for underground pipes. Inspectors should assess the impact of external corrosion on the pipeline, including its coating performance, corrosion defect repairs, and mitigation of corrosion protection faults.
After collecting more data to assess corrosion activity, apply the following prioritization requirements accordingly:
- Immediate Action Required – address all multiple severe corrosion indications in close proximity and isolated moderate corrosion indications in a region during the direct examination
- Scheduled Action Required – address all remaining moderate corrosion indications and groups of minor corrosion indications in a region during reassessments
- Suitable for Monitoring – inactive corrosion indications or any indications that have the lowest likelihood of ongoing or prior corrosion activity
Step 4: Post-assessment
Pipeline operators should define reassessment intervals and evaluate the overall effectiveness of the pipeline inspection four-step process. Perform direct examinations as needed and proactively seek continuous improvement opportunities for mitigative measures against pipeline corrosion.
Collecting, organizing, and managing paper-based pipeline corrosion inspection reports consume too much time, energy, and space.

Pipelines are integral to the operation of commercial, industrial, and even residential establishments. A damaged pipeline can severely affect the functionality of an establishment or, worse, force a full-stop to productivity. Considering the possible consequences, the thorough examination and proper maintenance of pipelines should not be taken lightly.
By using the iAuditor pipeline inspection software, pipeline engineers and safety inspectors can benefit from intuitive smartforms to maximize audit efficiency, streamline data collection, and improve team collaboration to ensure the effective maintenance of pipeline systems
Here are some tips on how to use iAuditor to optimize your pipeline inspection process:
Download, customize, and create intuitive pipe inspection templates
Our public library has over 100,000 pre-made inspection templates where pipeline maintenance personnel can download ready-to-use inspection templates from industry professionals. You can also convert your existing paper templates via smartscan or create a new one from scratch with our user-friendly, drag-and-drop template builder. Create versatile smartforms with iAuditor; no coding required.
Perform pipe inspections using your mobile device
You can use the iAuditor pipeline inspection software even if you are offline. The data you collect will automatically be saved via unlimited cloud storage upon connecting to the internet. With your smartform, you get a variety of response types, including yes/no, multiple choice, and freeform text, so you can collect the right information. Take pictures and annotate them for evidence and easy visual reference and immediately assign corrective actions to the right people mid-inspection so issues are resolved immediately.
Generate professional reports minus the hassle
Upon completing your pipeline inspection, you can generate a comprehensive report in seconds without having to manually compile your inspection data. Set up auto-share so that reports are automatically sent to the right people, saving you more time and energy. You can even hide/unhide report information to keep the focus on the most important details.
Review your inspection history via data analytics
One of iAuditor’s best features is data analytics. This feature analyzes collated inspection data and provides useful insight, such as frequently failing items, that can help you spot trends and identify patterns that may uncover the root cause of issues.
Track assigned inspections and corrective actions to ensure that everything is covered
Ensure accountability by having a pipeline inspection software that allows you to track the status of assigned inspections and corrective actions anytime, anywhere. Put mandatory answer fields in inspection templates and require digital signatures to ensure that inspections are done according to protocol.
iAuditor’s pipeline inspection software optimizes pipeline inspection processes in a number of ways. From easy smartform customization to automated reporting, iAuditor’s versatile mobile solution simply makes pipeline maintenance faster and easier.
A pipeline inspection software is used by pipeline engineers to assist them in periodic pipeline maintenance inspections. Pipeline maintenance inspections help ensure that pipelines are free from corrosion, leaks, and other types of damage that could endanger workers and negatively affect operations.
