Magnetic Particle Testing (MPT)

Magnetic Particle Testing (MPT)

Magnetic particle testing (MPT) is done in two steps. A magnetic current is passed through the area where the test is to be carried out. Magnetic metallic particles are spread over the test area, where the particles accumulate over the defect area. Aries Marine and Engineering Service Magnetic particle testing is used to detect defects like cracks at the surface in ferromagnetic metals such as iron, steel, nickel, cobalt and some of their alloys.

Magnetic particle testing (MPT) is a cost effective and reliable non-destructive test method for detecting critical flaws in ferromagnetic materials. Magnetic particle testing is used by Aries Marine mainly in oil & gas pipelines, offshore & onshore steel structures and various metal machinery components to prevent failures or accidents. We provide MPT service for oil and gas industry, petrochemical, industrial pipes, structural steel industry etc.

Magnetic Particle Inspection Process

The basic procedure that is followed by Aries Marine to perform magnetic particle testing are:

  • Pre-cleaning of component
  • Introduction of Magnetic field
  • Application of magnetic media
  • Interpretation of magnetic particle indications

Magnetic Particle Testing (MPT) is the economical and comparative faster non-destructive test method which is widely used in Oil & gas, industrial, Aerospace, Locomotive, automotive, power generation, nuclear, petrochemical industries.

Advantages of Magnetic particle testing (MPT)

  • Detect both surface and near subsurface indications
  • Can inspect parts with irregular shapes easily
  • Fast method of inspection and indications are visible directly on surface
  • Low cost compared to many other NDT techniques
  • Very sensitive test method
  • Detect tight in-service fatigue cracks in rotating parts or creep cracks on steam piping
  • Easy to use and requires minimal amount of training
