Magnetic Flux Leakage Testing in Singapore: Advanced Tank & Corrosion Inspection Solutions

MFL testing in Singapore is crucial for detecting corrosion, pitting, and metal loss in storage tanks and steel structures without causing damage. Since Singapore is an international hub for the marine, offshore, oil and gas, and petrochemical sectors, MFL inspection services in Singapore are critical in ensuring the integrity of assets, safety standards, and the reliability of operations.
Starting with refinery storage tanks and FPSUs to marine fuel tanks and industrial plants, magnetic flux leakage inspection will be used to identify corrosion at an early stage and avert expensive failures.

What is Magnetic Flux Leakage (MFL) Testing?

Magnetic flux leakage testing is a high-tech non-destructive testing (NDT) technique that is applied to identify corrosion and wall thinning in ferromagnetic materials, including tank floors, pipelines, and steel structures.
The mechanism of operation consists of magnetizing the steel surface with high intensity permanent magnets or electromagnets. Leakage of the magnetic field. When the magnetic field is exposed to a region of metal loss or pitting corrosion, the field leaks out of the steel. The sensors that sense these leaks are highly sensitive, and their position is mapped, and then the inspectors can visualize the status of the material.
MFL testing helps to:
  • Detect internal and external corrosion in tank floors.
  • Identify localized pitting and general wall thinning.
  • Perform non-intrusive tank inspections that save time.
  • Support comprehensive asset integrity inspection in Singapore.
  • Ensure safety compliance with API 653 and preventive maintenance goals.

Where Magnetic Flux Leakage Testing is Used

MFL is the screening tool of choice in large-scale steel assets in the industrial sectors of Singapore because of its speed and accuracy.

1. Storage Tank Inspection

The most widespread one is tank floor MFL inspection in Singapore, which covers 100 per cent of the floor plates.
  • Bottom plate inspection: The inspection of the health of storage tanks containing hazardous chemicals or fuel.
  • Floor plate corrosion: This is where the corrosion is found under the floor and is not visible.
  • AST (Above-ground storage tank) Inspection: It is necessary to have a look at the primary containment, which must be leak-proof.
  • Tank integrity monitoring: A health check of ageing assets based on data.

2. Oil, Gas & Petrochemical Facilities

The energy industry of Singapore in Jurong Island depends on the services of corrosion detection to avoid environmental risks and leakages.
  • Oil storage tank inspection: Essentials to refineries and bulk liquid terminals.
  • Petrochemical tank services: Inspection of aggressive chemical tanks.
  • Refinery tank floor scanning: Assistance to operators in meeting the standards of API 653 tank inspection.

3. Marine & Offshore Applications

The city of Singapore is considered to be a leader in ship repair and offshore engineering, so MFL cannot be neglected in maintaining the vessels.
  • FPSO tank inspection: The integrity of Floating Production Storage and Offloading units.
  • Marine fuel tanks: These are necessary in the bunkering of vessels and cargo ships.
  • Offshore asset integrity: Testing the steel structures that are under severe conditions in a salty environment.

How MFL Tank Floor Scanning Works

The current-day automated tank inspection technology involves robotic scanners to give high-resolution information in mapping.
  1. Magnetization: The scanner is moved over the steel, saturating the steel with a magnetic field.
  2. Scanning: Robot sensors move over the floor, and any disturbances in the magnetic flux are sensed.
  3. Detection: The system will detect pitting, grooving, or overall metal loss on the upper surface and on the lower surface.
  4. Digital Mapping: The software is used to create a map of the corruption, the exact position, and the extent of the flaws.
  5. Assessment: The data is used by the inspectors to plan the repairs or know the remaining life of the asset.

Benefits of Magnetic Flux Leakage Testing

  • Early Corrosion Detection: It detects defects early in the system and ensures that it does not turn into a leakage, thus saving the environment.
  • Non-Intrusive & Efficient: Scanners are able to scan large areas within a short period of time, meaning that they are able to cut down on the downtime of tanks to a considerable degree.
  • Cost-Effective: This is because companies can identify the areas requiring repairs, thus do not have to change the whole floor plate when it is not necessary.
  • Regulatory Compliance: Facilitates API 653 and ISO compliant inspection services that are compulsory to most of the Singaporean operators.
  • Precise Data: Digital reporting can be used to do the so-called trend analysis, which assists managers in determining when the next maintenance cycle will take place.

Compliance & Inspection Standards

All Tanks in Singapore are checked by professional certified tank inspection experts who observe codes internationally to make sure that all tests are valid and legal:
  • API 653: The global standard for tank inspection, repair, and alteration.
  • ISO 9712: Certification for NDT personnel to ensure technical competence.
  • ASNT Level II/III: Ensuring that the technicians interpreting the MFL data are highly qualified.

Choosing the Right MFL Inspection Company in Singapore

In choosing a partner with whom you will share your next shutdown or maintenance cycle, seek:
  • Experience: A history of refinery and offshore inspection.
  • Modern Technology: The utilization of the newest 3D MFL scanners and computerized mapping.
  • Certified Professionals: Inspectors who are certified by ASNT or PCN.
  • Safety Record: An organization that cares about the BizSAFE and WSH standards of Singapore.

Frequently asked questions: Magnetic Flux Leakage Testing in Singapore.

Q1. What is the key benefit of MFL when compared to Ultrasonic Testing (UT)?
Ans: MFL is far quicker in scanning big areas such as tank floors. UT is a great spot-checker of thickness but MFL can give 100 percent coverage in a fraction of the time.
Q2. Is MFL able to detect corrosion of the lower surface of the tank floor?
Ans: Yes. This is one of the most powerful aspects of MFL as it can scan the tank and pinpoint the corrosion of the soil-side as compared to the scanner scanning on the inside of the tank.
Q3. Does the tank require cleaning in order to do MFL testing?
Ans: Yes. To achieve the correct results, the floor should be wiped off of sludge and scale to ensure that the scanner is in a constant position with the steel surface.
Q4. What is the maximum time of the MFL tank floor scan?
Ans: It will depend on the size of the tank; however, a 20-meter diameter tank can be scanned in a working day and sometimes in two working days.
Q5. Is MFL environmentally safe?
Ans: It is completely non-destructive and does not use any chemicals, and therefore is considered one of the greenest methods of inspection.

Conclusion

Testing of magnetic flux leakage in Singapore is a critical instrument that is used to detect corrosion and metal loss on infrastructure. It doesn’t matter whether you are operating a refinery at Jurong Island or a shipyard at Tuas; MFL testing will ensure that your storage tanks and pipelines are safe, compliant and functioning.
Through the collaboration with a reliable MFL inspection services provider, you will be able to secure your assets, avert environmental catastrophes, and keep the structural integrity in the long term.
