CORROSION UNDER INSULATION
THE TRILLION-DOLLAR PROBLEM
40 TO 60%
CORROSION UNDER INSULATION
CAUSES CATASTROHPIC FAILURE
AND PROLONGED DOWNTIME.
OF PIPE MAINTENANCE EXPENDITURE
IS DOWN TO CUI THAT COSTS THE OIL AND GAS INDUSTRY AROUND
$1 TRILLION GLOBALLY PER YEAR
PREVENTING CUI
ARMAFLEX MITIGATES CUI.
ARMAFLEX WAS SUBJECTED TO A RIGOROUS
6-MONTH TEST
CLOSED-CELL FLEXIBLE ELASTOMERIC FOAM (FEF)
HIGHLY EFFECTIVE MOISTURE BARRIER
VAPOUR-TIGHT SEAMS THROUGH EXCELLENT ADHESION
LOW LEVEL OF LEACHABLE CHLORIDES
NEUTRAL PH VALUE
EASY MAINTENANCE AND INSPECTION
BY TNO/ENDURES B.V.
A TOUGH TEST
TNO/ENDURES B.V., CORROSION EXPERTS, INSTALLED
SALT WATER AT 35°C WAS SPRAYED ONTO THE PIPES OVER
6 MONTHS.
TWO PIPES COVERED WITH ARMAFLEX,
ONE WITH GRP CLADDING AND ONE WITHOUT.
CORROSION WAS GUARANTEED TO OCCUR.
INSULATION AND CLADDING HAD HOLES DRILLED IN DIFFERENT PARTS.

HOW DID
ARMAFLEX
MITIGATE THIS?
Drilled Holes
PIPE A
Adhesive
Cladding
PIPE B
Pipe
Drilled Holes
THE RESULT: CORROSION STOPPED
THE INDEPENDENT RESEARCH FOUND THAT:
WITH PIPE A:
ARMAFLEX CLOSED-CELL FEF MATERIAL USED IN
WITH PIPE B:
COMBINATION WITH ARMAFLEX ADHESIVE
LIMITS SPREAD OF CORROSION
“NO CORROSION”
TO AREAS JUST UNDER THE HOLES.
THE REPORT CONFIRMS THAT, AT THE UNDERSIDE OF THE PIPE:
“NO SIGNIFICANT CORROSION IS OBSERVED IN THIS AREA”
WATER INGRESS DID NOT PENETRATE THE INSULATION
