Positive Material Identification
As a result of a series of accidents resulting
from material mix-ups, many companies have instituted
stringent Positive Material Identification programs.
Industry organization has also worked to develop guidelines
to assure that the nominal compositions of all alloy
components in a process system are consistent with
design specification.

Inspection Consultants Limited are specialists in
testing materials for a range of imperfections and
defects – obviously this is vital to do where pipe
work, vessels or machinery is subject to great pressure
or continual wear, for example. We have various types
of equipment at our disposal to be able to offer a
complete testing service. We use industrial X ray
equipment such as Clandons Metascope.
This is used particularly in the field of Positive
Material Identification. Positive Material Identification
(or PMI) is a pretty specialized method of non-destructive
testing. It is used particularly to grade alloys and
carbon steels. It is used primarily for materials
such as stainless steel, where quality is really important.
This is particularly important where the correct grade
of material is critical for a particular capital installation
or project where the use of the material is being
stretched to the limits.
We use the latest x-ray fluorescence analysers which
is one of the methods for Positive Material Identification,
and low level radiation is fired at the material and
the energy levels reflected back from each element
is measured, so identifying the alloy elements.
