Internal inspection line corrosion

The visual inspection of vessel and equipment internals during periods of plant shut-down should be used to supplement information from on-line corrosion monitoring activities. [Pg.265]

Two steel tanks were removed from the same site and at the same time as the composite tank. There are no records to show how long these steel tanks were in service. One of the steel tanks was dusted with white metal oxide corrosion, while the other had signs of corrosion at the weld line. Rust had weakened the joint so much that the weld line could be scraped away with a pocket knife, revealing holes. Corrosive attack on an underground gasoline tank comes from both the inside and outside. An inside problem is moisture, which is often present in the fuel and settles at the bottom. Depending on various conditions, the moisture can create severe internal corrosion. But an inspection of the 25 year old composite tank showed no internal corrosion, even though there was moisture with the fuel on the bottom. [Pg.272]
