The corrosion susceptibility of steel storage tank systems is now well recognized by government regulatory agencies and most Provincial governments in Canada have introduced legislation making it mandatory that new tank installations incorporate corrosion control equipment and that existing tanks and piping be upgraded to […]
A 1985 study conducted by the Canada Mortgage and Housing Corporation stated that the overall cost of repairs to damaged parking structures in Canada was estimated at 1.5 to 3.0 billion dollars. Little has done in the intervening years to reduce these costs on existing […]
A 1954 survey by NACE Subcommittee TP- IHIII on oil-string casing corrosion indicated that 79% of failures on producing gas or oil wells in the U.S. were due to corrosion. Battle (3) extrapolated the NACE 1954 survey to estimate the number of casing failures in […]
The corrosion of flat bottom storage tanks has not been historically a serious problem to the petroleum refining industry. This may have to do in par with the fact that most tanks are constructed on elevated granular pads which afford good drainage and also as […]
The corrosion susceptibility of steel storage tank systems is now well recognized by government regulatory agencies since most Provincial governments in Canada have introduced legislation making it mandatory that new tank installations incorporate corrosion control equipment and that existing tanks and piping be upgraded to […]
It has been estimated that 5 to 10% of the approximately 200,000 petroleum product storage tank systems in Canada are leaking and about 40 to 50% of these are a result of corrosion perforations in the tankage.* External corrosion is responsible for about 85% of […]
Most metals exposed to a liquid phase corrosive environment can be protected from aggressive corrosion attack using an electrochemical prevention technique, either cathodic protection (CP), anodic protection (AP) or potential adjustment protection (PAP). Which of these methods of protection is appropriate depends primarily on the […]
