Crawler Cleaning & Inspections

A unique solution for high definition remote visual inspections.


Magnetic Crawler

Crawler cleaning & inspections offer several significant benefits, making them a valuable tool for assessing the condition and integrity of ferromagnetic structures. The key advantages of using magnetic crawlers:

  • Non-Destructive Testing (NDT): Magnetic crawler inspections are non-intrusive and do not require cutting into or damaging the surface under inspection. Traditional inspection methods might involve destructive testing, such as cutting into the structure to access the interior. Magnetic crawlers, on the other hand, adhere to the surface using magnetic wheels or tracks, allowing them to move smoothly without causing any damage. This non-destructive approach minimizes operational disruptions and reduces repair costs, making it a cost-effective and efficient inspection method.
  • Detection of Hidden Defects: Magnetic crawlers equipped with magnetic flux leakage (MFL) sensors can detect defects that may not be visible from the outside. For example, corrosion occurring within the walls of a steel pipeline or storage tank might not be evident from the surface. The MFL sensors can detect the magnetic flux leakage caused by such defects, enabling early detection and timely maintenance to prevent further damage or catastrophic failures.
  • Versatility: Magnetic crawlers are designed to navigate through complex surfaces, including pipelines, storage tanks, pressure vessels, and other metallic structures. They can move along horizontal, vertical, and inclined sections, making them suitable for various applications and industries. Their ability to adapt to different surfaces and configurations ensures comprehensive inspections, providing valuable data for asset integrity assessment.
  • Real-Time Data and Immediate Assessment: Magnetic crawler inspections provide real-time data as the crawler moves along the surface. This immediate data feedback allows engineers and inspectors to assess the asset’s condition in real-time. It enables quick decision-making, helps identify critical issues promptly, and allows for on-the-spot adjustments to inspection plans. The real-time data also facilitates faster data analysis and reporting, ensuring timely maintenance or repairs when necessary.
  • Enhanced Safety: One of the significant advantages of magnetic crawler inspections is that they eliminate the need for human entry into potentially hazardous environments. Inspecting confined spaces or working at heights can pose risks to human inspectors. Using magnetic crawlers allows inspections to be performed remotely, reducing the chances of accidents or injuries. This enhances safety and ensures compliance with safety regulations, creating a safer working environment for inspection teams.
  • Quantitative Data and Accuracy: MFL sensors used in magnetic crawlers provide quantitative data on the extent and severity of defects. The sensors measure the magnetic flux leakage caused by defects, allowing for accurate quantification of issues such as corrosion, pitting, or metal loss. The quantitative data facilitates informed assessments and planning for appropriate repair or maintenance strategies. Asset managers and engineers can make accurate decisions based on the data, ensuring cost-effective and targeted maintenance actions.
  • Time and Cost Savings: Magnetic crawler inspections offer time and cost savings compared to traditional inspection methods. The non-destructive nature of magnetic crawler inspections means there is no need for costly repairs or replacements resulting from destructive testing. The efficient and swift inspection process minimizes downtime and operational disruptions, reducing the impact on production schedules. The early detection of defects and timely maintenance also prevents the escalation of issues, saving significant costs in the long run.
  • Environmental Benefits: By enabling early detection of defects and facilitating timely maintenance, magnetic crawlers help reduce the risk of leaks or failures in pipelines and storage tanks. This proactive approach to maintenance can prevent potential environmental hazards, such as oil spills or chemical leaks. Consequently, the use of magnetic crawlers contributes to environmental protection and sustainability.

In conclusion, magnetic crawlers offer numerous benefits for inspections of ferromagnetic structures. Non-destructive testing, early detection of hidden defects, versatility, real-time data, enhanced safety, quantitative data, time and cost savings, and environmental benefits make magnetic crawlers an indispensable tool in various industries. Their ability to provide accurate and comprehensive data on the condition of assets ensures safe and efficient operations and aids in optimizing maintenance and repair strategies. As technology continues to advance, magnetic crawlers are likely to play an increasingly important role in asset integrity assessments and maintenance planning.
