What is the difference between underwater NDT and regular NDT? Underwater NDT inspections are specifically designed to assess structures submerged in water, such as subsea pipelines, pontoons, and steel piles. The key difference is that underwater inspections must account for the challenges of working in an aquatic environment, such as visibility, currents, and pressure. Regular NDT, on the other hand, is typically used for inspections above water. How do I know if my underwater structure needs an underwater magnetic particle inspection? If your structure is exposed to harsh underwater conditions or has been in service for a long time, it’s a good idea to schedule regular NDT inspections. Early detection of wear, corrosion, or other issues can prevent costly damage and ensure the safety of your infrastructure. What types of damage can underwater non-destructive testing detect? Underwater NDT can detect multiple issues, including corrosion, cracks, material thinning, and structural misalignment. These inspections help identify potential problems before they lead to significant damage or failure, ensuring your structure remains safe and operational. How often should I schedule underwater NDT inspections? The frequency of underwater NDT inspections depends on the type of structure and environmental factors. Typically, inspections are scheduled annually or biannually. However, more frequent inspections may be recommended for high-risk areas or critical infrastructure.

CONTACT US TODAY What is the difference between underwater NDT and regular NDT? Underwater NDT inspections are specifically designed to assess structures submerged in water, such as subsea pipelines, pontoons, and steel piles. The key difference is that underwater inspections must account for the challenges of working in an aquatic environment, such as visibility, currents, and pressure. Regular NDT, on the other hand, is typically used for inspections above water. How do I know if my underwater structure needs an underwater magnetic particle inspection? If your structure is exposed to harsh underwater conditions or has been in service for a long time, it’s a good idea to schedule regular NDT inspections. Early detection of wear, corrosion, or other issues can prevent costly damage and ensure the safety of your infrastructure. What types of damage can underwater non-destructive testing detect? Underwater NDT can detect multiple issues, including corrosion, cracks, material thinning, and structural misalignment. These inspections help identify potential problems before they lead to significant damage or failure, ensuring your structure remains safe and operational. How often should I schedule underwater NDT inspections? The frequency of underwater NDT inspections depends on the type of structure and environmental factors. Typically, inspections are scheduled annually or biannually. However, more frequent inspections may be recommended for high-risk areas or critical infrastructure.
