Magnetic Particle Inspection (MPI) Services in Malaysia – Complete Coverage of All Methods

Magnetic Particle Inspection (MPI), also referred to as Magnetic Testing (MT), is one of the most effective and rapid non-destructive testing (NDT) techniques used to detect surface and slightly subsurface discontinuities in ferromagnetic materials. At CT Precise Engineering Sdn Bhd, we offer comprehensive MPI inspection services across Malaysia — covering all major techniques including Yoke Method, Prod Method, Coil Technique, Central Conductor Method, and Wet Fluorescent MPI — ensuring unmatched accuracy and safety for industrial assets.

What Is Magnetic Particle Inspection (MPI)?

MPI works by inducing a magnetic field in the test material. When there's a surface-breaking or near-surface flaw, the magnetic field leaks out. Magnetic particles applied to the surface gather at these leak points, making the flaw visible to the inspector. This method is especially useful for inspecting:

• Welded joints
• Forged components
• Cast iron structures
• Steel plates, shafts, bolts, and fasteners

Explore All MPI Techniques Offered by CT Precise Engineering

CT Precise is equipped to handle every major MPI method, tailored to your specific component geometry, site conditions, and acceptance criteria.

• Yoke Method (AC/DC): Ideal for field inspections; portable and efficient. Used for weld seams and small parts.
• Prod Technique: Used for large components; allows current to flow directly through the part.
• Coil Technique: Generates circular magnetization; best for detecting longitudinal cracks in cylindrical parts.
• Central Conductor Method: Perfect for hollow parts or bores; magnetizes internal surfaces.
• Wet Fluorescent MPI: Most sensitive method, viewed under black light (UV-A); ideal for critical components in aerospace, oil & gas, and pressure equipment.
• Dry Particle MPI: Common in hot surface or rough component inspections.

Where We Apply MPI in Malaysia

CT Precise Engineering provides MPI inspections in various industries where ferromagnetic components are subject to cyclic loading, stress, or corrosion:

• Oil & Gas: Onsite MPI for pipelines, valves, and offshore rig structures
• Petrochemical Plants: Inspection of pressure vessels and nozzles
• Power Plants: Weld seams in boilers, turbines, and support frames
• Construction: Steel column joints and rebar welding
• Shipbuilding & Marine: Hull plates, shaft connections, propeller assemblies
• Fabrication Yards & Steel Workshops

Step-by-Step MPI Process Used by Our Certified Inspectors

1. Surface Cleaning: Remove rust, paint, oil, and dust for better flaw visibility.
2. Magnetization: Apply magnetic field using yoke, prods, coil, or central conductor.
3. Particle Application: Apply dry or wet magnetic particles (fluorescent or visible).
4. Visual Inspection: Observe any particle accumulations under adequate light or UV lamp.
5. Evaluation: Assess length, shape, and location of indications per international standards (e.g., ASME, ASTM).
6. Demagnetization: Use AC decaying or reverse polarity to remove residual magnetism.
7. Reporting: Record findings with high-resolution images and issue NDT reports.

Advantages of Using MPI

• Extremely sensitive to surface and near-surface flaws
• Quick and cost-effective for production and maintenance inspections
• Can be used on complex shapes and large surface areas
• Multiple techniques available for different applications

Limitations to Be Aware Of

• Only applicable to ferromagnetic materials (iron, steel, nickel alloys)
• Surface must be clean and dry
• UV fluorescent testing requires controlled lighting conditions
