CAPCIS LONG
TERM CORROSION TEST
CORROSION & PROTECTION CENTRE FOR INDUSTRIAL SERVICES,
MANCHESTER, UK, 1996
A joint-industry-program for evaluation of materials in flowing
seawater conducted the following test: DUOLINE 20 lined 3-1/2"
OD NS-CT-FGL pup joints were included in a flow loop test
where various coatings, linings and alloy steels were exposed
to seawater flowing at 23 ft/sec (7 meter/sec) at various
temperatures and with various levels of chlorine injection.
A series of short term exposures, totaling 300 days of liner
exposure, and a 365 day continuous flow test both revealed
that DUOLINE 20 was the only protection system to continue
protecting the steel throughout the test.
