... (<355 mm, or 14 in.) and 300 m (1000 ft) on larger pipelines. The current required for a segment of pipeline is calculated by using the current density required for the given environment, the surface area of the pipe segment, and the fraction of steel assumed to be bare. Anodes are then sized to fit...

... be expressed in terms of a threshold voltage below which cratering does not occur. As shown in Table 7 , zinc-coated surfaces have a lower cratering threshold voltage than bare steel and hence are more prone to cratering ( Ref 20 ). Although cratering can be avoided by reducing the voltage applied during e...
