Corrosion of Spiral Rib Aluminized Pipe, Summary Report.

摘要

Large diameter, corrugated steel pipes are a common sight in the culverts that run alongside many Florida roads. Spiral-ribbed aluminized pipe (SRAP) has been widely specified by the Florida Department of Transportation (FDOT) for runoff drainage. These pipes are expected to have a long service life, up to 75 years. However, the durability of SRAP has been challenged by a series of premature pipe failures due to corrosion. FDOT contracted University of South Florida researchers to study these failures and find their causes.
