How do QED's corrosion inhibitors work?
We
have had success with many variants of our products across
many industry sectors (Oil, Gas, Construction). For detailed
information on how our products work, trials and reports please click

an explanation of how migrating corrosion inhibitors work in concrete,
please click here. The principles also apply to the protection of steel
within our pipeline protection and other products.
For a comprehensive
scientific explanation of how QED's VPI works in concrete, select this
link. This contains an explanation of how corrosion occurs within
concrete, the effect of chlorides and carbonation and how VPI's address
this problem. You will also find the chemical formulas helping to
further explain the physical changes that take place over time.
The Proof - QED's own lab tests
For
details on tests conducted by QED, please click here. Some of our tests
are ongoing as corrosion tests must be carried out over periods of
anything upto 20 years to show meaningful results. All tests are
documented internally by QED and we take photographic evidence, as well
as welcoming third part verification.
QED
had concrete cubes embedded with our Margel 580 product submitted for
testing The testing was carried out by an independent testing house in
the UK, Click here for the results. These tests are being redone in the
UK currently, with more detailed results due in Mid-2008. The aim being
to accurately demonstrate the movement of the VPI vapours through
different qualities of concrete and the adsorbtion of the vapours onto
steel and hence protection given when using QED's VPI products.
Independent Testing by Geomaterials Ltd QED
in partnership with Makers Industrial Ltd, commissioned independent
verification that Margel VPI would travel through concrete. Here is a
copy of the report in Adobe PDF format.

non Steel items, such as aluminium, tin, copper, etc..
These pages show QED's early testing carried out on the VPI1000 impregnated pipe wrap products.
For the ultimate protection of Oil and Gas Pipelines.
