US - CSB Releases Technical Report on Chevron 2012 Pipe Rupture and Fire. Extensive Sulfidation Corrosion Noted

CSB Releases Technical Report on Chevron 2012 Pipe Rupture and Fire; Extensive Sulfidation Corrosion Noted

Washington, DC, February 13, 2013 - The U.S. Chemical Safety and Hazard Investigation Board (CSB) and the California Division of Occupational Safety and Health (Cal/OSHA) today released a technical evaluation report on piping samples taken from the Chevron Refinery in Richmond, California, where a hydrocarbon release and massive fire occurred on August 6, 2012. Cal/OSHA participated in this technical evaluation as part of its enforcement investigation.

The report, prepared by Anamet, Inc., a metallurgical laboratory in Hayward, California, concludes that the 8-inch steel pipe, from a section designated as 4-sidecut which was installed in 1976, ruptured due to severe sulfidation corrosion, and that tested pipe samples showed a very low concentration of corrosion-inhibiting silicon.

CSB Chairperson Rafael Moure-Eraso said, “The report, resulting from a cooperative effort between the CSB, Cal/OSHA, the United Steelworkers (USW), and Chevron provides a solid, technical basis for the firm conclusion that the pipe corroded over time from sulfidation corrosion. We hope this report receives widespread attention throughout the petrochemical industry as a precaution to all refiners to carefully examine potential corrosion mechanisms and use the safest possible materials of construction to avoid failures. Refineries and other plants must incorporate strong mechanical integrity and inherently safer strategies in their process safety management programs.”
The Anamet report provides the following conclusions:

1. Rupture of the 8-inch 4-sidecut resulted from wall thinning caused by sulfidation corrosion.

2. Post rupture corrosion destroyed fracture morphology that could have indicated the rupture initiation site. However, rupture likely originated in the thinnest region and initially followed a longitudinal path driven by the hoop stress. Consequently, an area of likely rupture initiation was identified.

3. The wall thickness of the ruptured section was less than all the other sections of the 8-inch 4-sidecut that were evaluated.

4. Chemical analysis showed the silicon concentration of the ruptured section was 0.01-wt%.

5. Six of twelve specimens (50%) from unique sections of the 8-inch 4-sidecut, 12-inch 4-sidecut, and 2011 12-inch samples were found by chemical analysis to have a silicon concentration of less than 0.1-wt%.

6. Deformation of a small region of the 8-inch 4-sidecut rupture edge was consistent with mechanical force applied from the outside surface of the pipe, possibly from a fire pike, such as samples E-099 and E-082-2, or other pointed object. This deformed region was located within the area of likely rupture initiation.

Cal/OSHA has already issued 25 citations and civil penalties of $963,000. Chevron has announced it will appeal these citations.

India - Corrosion induced Oil Pipeline Leak worries residents in Tiruvottiyur, Chennai. CPCL asserts facility health through external protection by CP. Is internal corrosion overlooked?

Residents have been complaining of seepages from the CPCL pipeline; oil company asserts facility is in good health

A leak in an underground oil pipeline in Tiruvottiyur on Friday set off panic among residents even as oil company officials initiated immediate action to plug the hole and clear the contaminated soil on Ottravadai Street. While CPCL officials said that the pipeline was being monitored regularly and no abnormality had been detected, TNPCB officials, who inspected the spot, said the leak was due to corrosion.

Residents said the leak was first been noticed at 6.30 a.m. By 8 a.m., the area was cordoned off by Chennai Petroleum Corporation Limited (CPCL) with the assistance of the fire service personnel and Central Industrial Security Force. Soon, the excavation of the area began and the workers kept throwing mud on the oil collected in the pit dug up to plug the leak on Ottravadai Street. Chennai Corporation Councillor Prabhakaran said the residents have been complaining about the oil leak for the past few months. Many wells and bore wells in the residential locality have been closed because of oil contamination. CPCL officials said the leak had been plugged by evening.

As a school was located on the same street where the leak occurred, officials asked residents to avoid cooking or using LPG stove for any other purpose till the hole was plugged. “The discharge of oil has intensified over the past two years. Luckily today, no vehicles skidded on the oil patch,” said S.Damodaran, a resident.

The 30-inch oil pipeline runs for a distance of 6.9 km underground and 300 metre above ground level. “The pipeline has been properly assessed for its health periodically. CPCL has been taking extraordinary precautions to periodically inspect the health of the pipeline. The pipeline is protected by impressed current cathodic protection system and monitored every week. Walk-through inspections of the pipeline are done every fortnight. Extensive condition assessment studies of the pipeline are done once in four years and the last exercise was done by Engineers India Limited (EIL) in December in 2012,” a CPCL release said.

Canada - Corrosion Education - iPhone App on Corrosion developed by University of Toronto Engineering Student

Corrosive behavior? There's an app for that on iphone

Corrosion iPhone app developed by University of Toronto engineering student Jason Tam is finding a grateful audience among professional engineers and engineering students.

Tam created the app last year when Professor Steven Thorpe asked his MSE 315 Environmental Degradation of Materials students whether anyone would be interested in developing an app that provided corrosion terminologies, formulae, and benchmarking data.

Thorpe had originally hoped to find an existing app that students could use in the course, which primarily deals with electrochemical and corrosion behavior of engineering materials in various applications. He could only find one less-than-ideal app in the iTunes store that didn’t even spell 'corrosion' correctly.

The app now sells for 99 cents on the iTunes app store and all proceeds go to the George B. Craig Scholarship, an in-course award designated for an academically high-performing upper-year Materials Engineering student with demonstrated financial need.

The app includes a glossary of more than 300 technical corrosion engineering terms, a list of constants, such as the Boltzmann constant, reference electrodes and schematics, and even virtual corrosion experiments. For example, you can explore crevice corrosion on the Titanic.
