摘要
Failure statistics for onshore pipelines transporting oil, refined products and natural gas from the USA, Canada and Europe are compared. Failure data from Brazilian pipelines are presented and included in the comparison. Failure rates for internal and external corrosion, human action and natural forces are analyzed and the expected failure rate for each failure mechanism is indicated. The effects of relevant construction and environmental factors on the failure rates are studied and mean trends are obtained. Furthermore, the sizes of the holes observed in each type of failure are also compared. Finally, the probability of ignition after a failure in gas and liquid pipelines is evaluated. This study may serve as basis for the estimation of failure frequency, hole size and probability of ignition for hazard liquids and gas pipelines.
