SAN FRANCISCO (AP) - Tests of pipe samples from Chevron Corp.'s refinery in El Segundo found corrosion to an extent similar to the pipe that failed and caused a large fire at the company's Richmond facility.
The federal Chemical Safety Board and California Division of Occupational Safety and Health issued a report Thursday that found up to 60-percent wall loss in a pipe at Chevron's El Segundo refinery that processes the same type of crude.
Chevron voluntarily inspected pipes at its El Segundo crude unit after the Aug. 6 fire in Richmond caused by a corroded old pipe.
Tests found that corrosion in El Segundo had damaged pipe samples in ways similar to the one that failed in Richmond, though not as extensively.
Chevron has replaced the damaged pipes.
