Magnetic Particle Testing (MT)

Magnetic particle inspection (MT) is a non-destructive testing method used to detect surface and
slightly subsurface flaws in ferromagnetic materials (such as carbon steel). It is used routinely to inspect
welds, piping, pressure vessels and structural steel components.

Applications

This test is applicable to the following infraestructures:

New fabrication welds for code compliance:
ASME Section V for pressure vessels, ASME B31.1 and B31.3 for piping and API 1104 for pipelines
Castings and forgings, valves and their components,
machined parts, pressure vessels, cranes and structural steel welds for cracks, non-fusion, cold laps
In-service welds

Advantages

The main advantages of this service are:

Flaws are highly visible
The equipment is portable and can be battery powered
Light enough to take easily onto scaffolding
Non-hazardous to operations or other nearby personnel
Very good sensitivity to fatigue cracking, tight fusion, HIC and SCC

Equipment

Equipped with the following products:

AC Magnetic Yoke: MATCON MAT 230
Permanent Yoke: The MAG-1 magnet is ideal for the effective magnetization of components for crack detection, particularly where the use of electromagnetic yokes is impractical or prohibited for safety reasons
Srem products: FLUXO 3 (Black magnetic Ink)
FLUXO 4 (White contrast paint)
Accessories for cleaning and preparing the surface or piece for inspection, and clean up after carrying out test
