SAN FRANCISCO (AP) — Tests of pipe samples from Chevron Corp.’s El Segundo refinery found corrosion to an extent similar to the pipe that failed and caused a large fire at the company’s Richmond facility, a report released Thursday found.

The tests found up to 60 percent wall loss in a pipe at the El Segundo refinery that processed the same type of crude as its sister facility in Northern California, according to the U.S. Chemical Safety Board and California Division of Occupational Safety and Health.
