NDT Testing Procedures

Ensuring the structural integrity and operational safety of every marine spare part we supply through rigorous Non-Destructive Testing.

At UTS Marine LLP, quality is never compromised. Marine environments subject machinery to extreme stress, high temperatures, and immense pressure. To guarantee that our reconditioned marine spare parts—from cylinder liners to crankshafts—perform flawlessly, we employ comprehensive Non-Destructive Testing (NDT) conducted by certified Level II and Level III technicians.

1Magnetic Particle Inspection (MPI)

MPI is a highly sensitive test used to detect surface and slightly subsurface flaws in ferromagnetic materials. We utilize this method extensively on crankshafts, connecting rods, and piston crowns to ensure no fatigue cracks exist that could lead to catastrophic engine failure.

  • Identifies hairline cracks invisible to the naked eye.
  • Critical for high-stress rotating components.

2Ultrasonic Testing (UT)

UT uses high-frequency sound waves to detect internal imperfections and measure the thickness of materials. This is vital for verifying the structural integrity of cylinder heads, engine blocks, and pump casings.

  • Detects deep internal voids or porosity.
  • Measures remaining wall thickness against OEM discard limits.

3Hydraulic Pressure Testing

Components subjected to fluids under pressure—such as cylinder covers, coolers, heat exchangers, and marine pumps—are hydro-tested. We pressurize the component beyond its normal working limits to verify there are no leaks or structural weaknesses.

4Hardness Testing & Calibration

We test the surface hardness of crucial components like piston ring grooves and valve spindles to ensure they can withstand extreme friction. Additionally, dimensional calibration is performed using micro-meters to guarantee parts fall within OEM acceptable tolerances.

Need Certified Marine Parts?

Every component supplied by UTS Marine LLP is accompanied by a detailed test certificate. We can also arrange for third-party inspections by IACS members.
