Large Stand-Off Magnetometry (MMM Technology)

Petromaster is the sole service provider for this service in the GCC, which is based on the  detection of the Self Magnetic Leakage Fields (SMLF), arising in ferromagnetic and paramagnetic products on accumulations of high-density dislocations to detect high-Stress Concentration Zones (SCZ’s).

This technology can be used on contact and non-contact bases to access ferromagnetic piping and pipeline external and internal conditions. It can be used on bare, insulated, and buried piping. This technology coupled with RBI can be used to optimally improve OSI select locations for further monitoring.

The MMM method uses natural magnetization and after-effect displayed as the magnetic memory of metal to actual strains and structural changes in products and equipment metal.

Applications of MMM

Non-Contact Method of Inspection for buried Pipelines

NCMD was developed using the specialized multi-channel highly sensitive flux gate sensors as a unit of TSC-type instrument. The main task is detection of potentially dangerous segments of buried pipelines by MMM technology. NCMD is based on distortions analysis of the magnetic field of the earth, conditioned by buried pipeline metal state including its stress-strained state.

• Diagnostic of boiler and furnace tube
• Express method of vessels inspection
• Diagnostics of steam turbine blades
• Diagnostics of corrosion under insulation (CUI)

Petromaster’s Metal Magnetic Memory (MMM) Testing provides an advanced, non-destructive inspection method for identifying early signs of stress concentration and potential damage in critical industrial equipment. The technology supports proactive asset integrity management by helping engineers focus inspection efforts on areas with the highest risk of failure.

Early Detection of Potential Failures
Enables the identification of developing defects and potential failure risks in critical industrial equipment, particularly within high-risk Stress Concentration Zones (SCZ).

Sensitive to Microstructural Degradation
The contact-based MMM method is sensitive to changes in the microstructure of materials within Stress Concentration Zones, helping detect early-stage fatigue damage and degradation before significant failure occurs.

Passive Non-Destructive Inspection
MMM is a passive inspection technique that does not require external magnetization or induced magnetic fields, making it a practical and efficient method for asset integrity assessment.

Minimal Surface Preparation
The technique requires minimal or no special surface preparation, helping reduce inspection time and operational disruption.

Cost-Effective Inspection Strategy
MMM testing helps optimize inspection resources by identifying critical Stress Concentration Zones for detailed examination. This can reduce the need for extensive full-length screening of large pipelines and other assets, lowering inspection costs while supporting effective risk-based maintenance planning.
