This paper discusses a classic example where the facts surrounding the failure of a lining system were ignored and undue reliance was placed on laboratory analysis. This “blind faith” in analytical data without a sound causal theory caused the failure analysts to disregard or overlook the obvious.

Too often, coating failure analysts ignore the evidence in front of them and obsess with hi-tech analytical analysis simply because it is available to them, or perhaps because that is was they themselves are in the business of doing. This tendency to rely on hi-tech test data to find a conclusion that supports a biased point of view is the wrong way to approach failure analyses, but it can impress and even dazzle. Frequently, this overuse of analytical methods complicates logical and accurate failure analysis work. This paper discusses a classic example where the facts surrounding the failure of a lining system were ignored and undue reliance was placed on laboratory analysis. This “blind faith” in analytical data without a sound causal theory caused the failure analysts to disregard or overlook the obvious.

10002 Failure Analysis of Three Layer Polypropylene Pipeline Coatings

Product Number: 51300-10002-SG

Three layer polypropylene (3LPP) pipeline coatings failed prematurely in the oilfields of Abu Dhabi in the United Arab Emirates (UAE). A failure investigation and analysis into this phenomenon was instigated. The coating disbondment has been found to be due to high residual stress concentration and adhesion loss.
