We are ISO 9001 certified, Constructionline approved, and have extensive experience with a team of specialists dedicated to quality and compliance.
S.T & W Inspections delivers precise industrial MPI test services, ensuring every weld, pipe, and structural steel component meets rigorous safety and compliance standards.
Understanding Industrial MPI Test Services
The Role Of Magnetic Particle Inspection
Magnetic Particle Inspection (MPI) is a specialised non-destructive testing method designed to detect surface and near-surface defects in ferromagnetic materials. By magnetising a component and applying iron particles in liquid or dry powder form, technicians can identify irregularities that disrupt the magnetic field. These disruptions highlight cracks, seams, or laps that could compromise performance or safety.
Why MPI Matters For Welds, Pipes, And Structural Steel
Components such as welds, pipes, and structural steel are often subjected to high levels of stress. Even minor defects can lead to serious failures if left undetected. Industrial MPI Test Services allow engineers and quality teams to:
- Detect fine surface cracks in welded joints and structural components.
- Inspect complex shapes and confined spaces made from ferromagnetic materials.
- Ensure compliance with British Standards and industry safety regulations.

Applications And Advantages Of Industrial MPI Test Services
1. Weld Inspection
Welds are critical for structural integrity, but defects such as porosity, incomplete fusion, or cracks can go unnoticed. MPI testing ensures:
- Early detection of surface discontinuities before assembly.
- Welds meet engineering specifications and safety standards.
- Reduced risk of in-service failure or structural compromise.
2. Pipe Assessment
Pipelines carry fluids under pressure, so surface flaws are a significant safety concern. MPI is particularly valuable for:
- Identifying longitudinal and circumferential cracks.
- Inspecting ferromagnetic pipes with irregular shapes or confined areas.
- Maintaining safety in heating networks, industrial pipelines, and gas lines.
3. Structural Steel Components
From industrial frameworks to bridges, structural steel demands thorough inspection. MPI testing provides:
- Early detection of flaws in load-bearing components.
- Verification that fabricated steel complies with BS EN ISO 9001 standards.
- Cost savings by preventing the need for destructive testing or replacements.
4. Fluorescent MPI For Sensitive Components
For components that cannot be coated with contrast paint, fluorescent MPI offers an alternative using fluorescent ink and a UV lamp. This method is ideal for:
- Small or intricate components.
- Aerospace, rail, and automotive applications.
- Critical assemblies where visual integrity must remain intact.
5. Advantages Of Industrial MPI Test Services
- Portability: Conducting onsite inspections with handheld equipment reduces downtime.
- Cost-effectiveness: Efficient detection prevents expensive failures.
- Versatility: Applicable across rail, oil, chemical processing, and power generation industries.
- Compliance: Ensures adherence to British and international standards and regulations.

Maximising Asset Reliability With Industrial MPI Test Services
Industrial MPI test services do more than identify defects; they play a crucial role in maximising the reliability and longevity of your critical assets.
1. Proactive Detection To Prevent Failures
Regular MPI inspections detect microcracks and surface irregularities before they develop into serious structural issues, thereby reducing the risk of operational failures.
2. Supporting Predictive Maintenance
Integrating MPI into maintenance schedules allows predictive, data-driven decisions. This ensures repairs are performed based on component condition rather than estimated service life, optimising resources.
3. Reducing Unplanned Downtime
By identifying issues early, MPI helps prevent unexpected breakdowns, keeping production lines, pipelines, and structural systems operational and safe.
4. Cost Efficiency And Asset Longevity
Consistent MPI inspections prevent expensive emergency repairs, extend the lifespan of welds, pipes, and structural steel components, and maximise the return on investment of critical infrastructure.

FAQs
1. What is the difference between MPI and Liquid Penetrant Testing?
MPI is suitable for ferromagnetic materials and detects surface and near-surface cracks using magnetic fields and iron particles. LPI is used for non-ferrous materials such as aluminium or stainless steel and relies on liquid penetrants to reveal surface flaws.
2. Can MPI be performed on complex or irregular components?
Yes, MPI is highly versatile and can be applied to components with irregular shapes, confined spaces, or small parts, making it ideal for welds, pipes, and structural steel.
3. How quickly can inspections be carried out?
Our technicians at S.T & W Inspections can be on-site at short notice. On-site MPI testing is completed efficiently without causing project delays.
4. What industries use Industrial MPI Test Services?
Industries including rail, oil and gas, chemical processing, structural steel fabrication, power generation, and district heating networks rely on MPI for quality assurance and compliance.
