The variation of the structure-to-electrolyte potentials and the effect of polarization cell replacement units can influence the results and conclusions on the pipeline’s polarization. To address these effects, data from a case study is analyzed to illustrate added testing procedures.
Many pipeline companies ignore the occurrence of external corrosion when cathodic protection (CP) is considered adequate. In these situations, understanding the failure mode of the coating and why CP cannot adequately protect the pipe under certain disbonded coating types is critical.
The interiors of large pipelines carrying corrosive liquids may be lined with a suitable coating and protected with a strip-type galvanic anode material. If the pipe interior is bare, relatively large amounts of current may be needed.
By using a combination of metal and polyethylene pipes in the new pipeline network and increasing the electrical resistance of the interference circuit, the problem of cathodic protection (CP) interference in the new network was solved.
Duplex stainless steels show excellent corrosion resistance and double the strength compared to standard austenitic steels. Composite and bi-metallic tubes are used where process conditions require properties and cost evaluations that cannot be met only by one material.
In a panel discussion, member leaders Dawn Eden and Sandy Williamson share their insights regarding materials sustainability and the latest trends in 2024. Discussion topics include new focus areas within AMPP’s Sustainability Task Force; key takeaways and insights from the 2024 conference; and what could be on the horizon as global outreach is ramped up.
Paul Vinik inspected hundreds of bridges as a structural materials engineer. Now, as AMPP’s chairman of the board, he wants to build bridges to give the next generation opportunities in the coatings and corrosion industry.
Selection criteria for MP’s biennial awards program include establishing the industry’s need for each innovation; explaining the process used for development and implementation; an evaluation of any testing results; and identifying criteria used to determine its success.
Safety, cost savings, and environmental protection were the leading priorities when a team at Deepwater Corrosion Services set out to retrofit three of the world’s deepest oil and gas platforms off the California coast.
Artificial intelligence (AI) will lead to a promising future for our industry and is not to be feared, renowned physicist Dr. Michio Kaku told conference attendees in New Orleans as the keynote speaker for the 2024 AMPP Annual Conference + Expo.
From informative programs and industry workshops to widespread exhibits and networking, AMPP’s 2024 show featured updated information and research regarding materials, corrosion and coating trends, and best practices and products.
As the global authority in materials protection and performance, AMPP recently announced the recipients of its 2024 service, technical, project awards. These awards were presented and celebrated at Honoree Night, held in March at the association’s annual conference.
In a newly released investigative report, the Transportation Safety Board of Canada says external corrosion led to a natural gas pipeline rupture near Fox Creek, Alberta, which caused an explosion and fire near a small community.
The 2024 version of the AMPP Annual Conference + Expo takes place from March 3-7 in New Orleans, Louisiana, USA. Through our exclusive Show Daily coverage, here’s our look at the event’s key highlights, along with updated information on scheduling and beyond.
The Association for Materials Protection and Performance (AMPP) already has a full slate of peer-reviewed symposia, workshops, networking events, technical meetings, and much more scheduled for its March 2024 gathering in the Crescent City.
