NACE: CORROSION COSTS $2.5 TRILLION ANNUALLY
Every year, corrosion causes an economic
damage of more than $ 2.5 trillion
worldwide. Therefore, the prevention of
corrosion, is an issue that plays an important
role in many areas. The new MMS® Inspection
series that is optimized for corrosion
protection reliably supports the inspector in
assessing corrosion-exposed components
and in jobs that involve checking of
corrosion protection.
Corrosion is the deterioration of a metal
as a result of chemical reactions between
it and the surrounding environment. This
leads to a functional impairment of the
metallic component over time. Accordingly,
rust formation on a railroad track is not
harmful, since the function of the rail is
not diminished. However, a pipe which has
become leaky due to pitting corrosion is
clearly defective, since the safe transport
of liquids is no longer guaranteed. The
same applies to the maritime sector, where
material surfaces attacked by corrosion on
ship walls can quickly become a safety risk.
There are serious consequences caused by
corrosion in engineering structures such
as bridges. If the steel structure corrodes
without any control, a bridge can quickly
become a threat to those who move on it.
Furthermore, there are economic advantages
to implementing proper corrosion
prevention methods.
In order to protect metallic materials against
environmental influences and thus corrosion,
in most cases coating with suitable corrosion
protection material is sufficient. The expense
for this – passive – corrosion protection is
relatively low in relation to the costs caused
by corrosion such as loss of value, downtime,
dismantling, etc. For companies and
institutions saving on corrosion protection,
it usually becomes expensive to repair the
damages afterwards. This is especially so for
structures that are very difficult to access
after installation, such as offshore wind
turbines. Corrosion protection involves
regular inspection and checks for proper
functioning. This means that inspectors
and service personnel need to use targeted
measurements to inspect if the quality of
the corrosion protection coatings still meet
specified standards.
With regard to coating thickness gauges
used here, both magnetic induction method
and eddy-current testing have established
themselves as standards worldwide.

Depending on the version, modern gauges
such as the newly developed MMS®
Inspection series from Helmut Fischer offer
both measuring methods.
Helmut Fischer has made every effort to
ensure the convenience of the user. For
this reason, international measurement
standards such as SSPC PA2 (Level 1-5), IMO
PSPC, ISO 19840, Australian AS 3894.3-2002
or Swedish IS 1841 60 are firmly integrated
as pre-configured batches or measurement
specifications via the software. The dew
point measuring device MMS® Inspection
DPM, which belongs to the same series,
measures the dew point before the corrosion
protection paint is applied. This helps to
ensure that the coating is applied under
proper environmental conditions. If the
conditions are not suitable, premature
corrosion may occur or the paint may peel
off as a result of poor adhesion.

Helmut Fischer has designed this series
of gauges to make corrosion protection
inspection considerably easier. This enables
many companies around the world to avoid
corrosion damage and the resulting loss of
value.
