VPI 1020 Anti-Corrosion Patch System

Description: QED’s anti-corrosion patches are pre-impregnated with QED’s
Margel™ corrosion inhibitor. Patches are applied directly to steel pipes and pipelines
to provide total protection from corrosion for a period of 10-15 years. The patches are
over-wrapped with insulation (where appropriate) and a final layer of tape.  
 
The patches are suitable for application on exposed steel pipes of all sizes being
equally effective on both new and heavily corroded steel. In comparison to other anti-
corrosion treatments the steel surface of the pipe to be protected requires no
preparation; the only requirement is the patch is placed on the steel surface to be
protected.  
 
The Margel™ corrosion inhibitor is proven in practice and provides a highly effective
corrosion resistance layer on steel by coating with a mono-molecular chemical layer
which inhibits corrosion. The outer cores of the tape will seal the vapour given off by
the Margel corrosion inhibitor, containing it within the tape ensuring that it protects
the steel of the pipe.
 
The patch and tape system are engineered to withstand continuous temperatures of
up to 149ºC.
 
The supplied tape is coated with a special acrylic pressure sensitive adhesive system
which combines superior quick stick at normal temperatures and also at extreme low
temperatures. The serviceable life of the tape is expected to be in excess of 15
years. The special laminated construction of the tape makes it highly puncture and
tear resistant as well as flame retardant.
 
Applications: The tape used to wrap the pipe is proven in the petrochemical and
cryogenic industries as a vapour barrier closure system. With the Margel™ migrating
corrosion inhibitor the combined product is extremely effective in combating
Corrosion Under Insulation (CUI).
