Description
Eighty six ERW pipes that failed in practice by grooving corrosion have been examined in order to obtain metallurgical and environmental factors involved in the occurrence of this type of corrosion. The penetration rate is 12mm/y at maximum and 2mm/y in average. Higher penetration rates are associated with low specific resistance of the environment. However, the specific resistance is not a “go”-or-“no go” criterion because grooving corrosion still occures in environments of very high specific resistance, e. g., 10, 000Ω-cm. Chemical composition of steel has no apparent bearing with susceptibility to grooving corrosion. Galvanizing retards the initiation of grooving corrosion, but its beneficial effect is limited because the protective film is lost eventually by corrosion. The present knowledge does not allow to predict the occurrence of grooving corrosion in ordinary ERW pipes.
