Corrosion in the News: November 18, 2019 Roundup

Key Takeaways

This week's stories take a look at corrosion of drinking water pipes, additive manufacturing and exciting developments in the corrosion resistance of 3D printed materials, and revisiting a story about corrosion at an elementary school.

Welcome to the mid-November edition of the Corrosionpedia News Roundup. For this edition, corrosion of drinking water pipes is highlighted in two separate stories. Additive manufacturing gets a special mention as exciting developments continue in the corrosion resistance of 3D printed materials. We also go back to the elementary school mentioned in the previous News Roundup as the story continues to evolve around the school and its corrosion issues.


ASTM Releases New Iron Pipe Standards

ASTM International has recently released a new standard that specifies characteristics for iron pipes used to transport drinking water. The specification comes at a time when contamination of drinking water due to pipe corrosion is under intense scrutiny. The intent is to provide even clearer guidance on what types of iron pipe materials should be used for drinking water applications. In addition to this latest release aimed at preventing corrosion contamination in iron pipes, other pipe material specifications are available from ASTM International that give some best practices for preventing corrosion.

New Project to Help Prevent 3D Printed Material Corrosion

3-D Systems, a leader in additive manufacturing, announced in October that it won a contract to develop a Corrosion Performance Design Guide for additive manufactured parts that are nickel-based. The guide will primarily focus on 3D printed nickel alloys in saltwater environments. The United States Department of Defense is helping to fund the project, and a big focus will be on the shipbuilding industry. The University of Akron, Newport News Shipbuilding and Northrop Grumman will be collaborating with 3-D Systems to develop the guide. They will provide 3-D systems with information about the current difficulties they have experienced with nickel alloys in saltwater environments so that 3-D Systems can target areas where corrosion has been especially difficult and costly.


Corrosion at California School Draws Political Attention

In the previous Corrosionpedia News Roundup, we wrote a story about James Madison Elementary, a school in California that had structural corrosion so advanced that it was enough to justify temporarily closing the school. Now, Raul Ruiz, a California congressman, has used the corrosion-induced shutdown as an example to persuade the United States House of Representatives to provide additional funding to upgrade public schools. Emphasizing to Congress that there are more schools out there that are at risk of corrosion and other structural concerns, he promoted the Rebuilding America’s Schools Act. The bill would allocate billions of dollars towards school construction in the United States.

Corrosion and Prevention Conference Beginning Soon

The Australasian Corrosion Association Inc. (ACA) is about to kick off its annual Corrosion and Prevention Conference, which runs from November 24 through November 27 in Melbourne, Australia. One of the largest corrosion conferences in the world, the Corrosion and Prevention Conference will highlight industry trends, state-of-the-art corrosion prevention technologies and keynote speakers. On top of the many exciting corrosion-related events this year, there will also be the Women in Corrosion Breakfast that celebrates women in the corrosion prevention industry. There will also be awards ceremonies and events for young professionals.

United States National Laboratory Researches Corrosion Detection Improvements

The National Energy Technology Laboratory (NETL) in the United States is beginning to research new sensor technology that will be able to better detect corrosion in oil and gas pipelines. In its current state, corrosion detection of pipelines usually occurs at periodic intervals. The project being undertaken by NETL aims to provide real-time, continuous feedback on the state of a pipeline as it undergoes corrosion. New electrochemical sensors being explored include fiber optics technology and have the potential to be more reliable and more accurate than previous sensors. The successful development of advanced sensors could result in fewer pipeline leaks that are caused by corrosion.

Lead in Drinking Water Caused by Pipe Corrosion

Recently tested drinking water in Montreal, Canada has been found to contain excessive lead levels, with the lead content exceeding the minimum amount by over a multiple of three in at least one instance. The study was carried out by the Toronto Star, the National Observer and the Institute of Investigative Journalism.


The reason for the lead contamination is corrosion of its old, outdated lead water pipes. As the lead pipes corrode, lead particles are released from the pipe walls and make their way into the drinking water. This has been a problem in many places recently, and Montreal is working to replace its lines. Water additives can also be used to slow the corrosion rate until the lead pipes are replaced.
