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.
Paints and coatings manufacturer Sherwin-Williams recently announced top honors in its annual Impact Award program. This year, first place was awarded to a landmark infrastructure upgrade in Fargo, North Dakota, USA, which aims to boost wastewater treatment capacity.
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.
AMPP’s SC 08—Metallic Material Selection and Testing, SC 05—Surface Preparation, and SC 26—Carbon Capture, Alternative Fuels, and Energy Storage are among the Standard Committee (SC) groups that have begun new projects in recent months.
After undergoing rigorous testing to ensure suitability for dry food contact, a breakthrough was achieved with the successful application of Belzona’s 5811 immersion-grade epoxy coating. This cutting-edge tank lining was recently installed at a flour mill in Belgium.
The most common alloys used for exposure at high temperatures are the iron/nickel/chromium alloys, often referred to as stainless steels (SS). The materials used may be cast or wrought.
Sam Scaturro, president of Alpine Painting & Sandblasting Contractors, recently joined AMPP’s podcast series to reflect on his leadership journey within the company and the association. Topics include Alpine’s emphasis on safe and sustainable practices, as well as updated strategies for workforce development and communication with clients.
Although the primary focus of a corrosion engineer is on the chemical stability and corrosion resistance of these materials, it is critical to cooperate with other design team members familiar with the mechanical, physical, and other properties to ensure that the desired materials performance can be achieved.
According to Utah State’s primary researcher involved in the study, one of the most important indicators for identifying failing pipelines is water main break rates. Pipe performance continues to be impacted by soil corrosivity, and the replacement of asbestos cement and cast-iron pipe is creating a shift in predominant pipe materials.
With a third-party inspector on site, clients can get material delivered correctly the first time, and thus save money in the long run. It also helps to avoid the domino effect of causing stress on the project team, the facilities, and field inspectors, if the material isn’t delivered appropriately.
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.
A number of fundamental measures can be taken to address the problem of reinforcing steel corrosion. However, an important distinction has to be made in the applicability of remedial measures to new versus existing structures.
After finding a water leak from its holding tank, the owner/operator of a town water tower reached out to Total Access Solutions Co. (TASC) to request an inspection. One TASC got on site, investigators were able to deduce more information about the potential cause(s) of the premature failure.
Significant changes are expected for U.S. federal hazard communications and for lead standards in California, and industrial painters should be especially vigilant because the impacts could be dramatic, according to a leading regulatory expert.
When compared with metals, polymeric materials tend to be more resistant to chloride ions and hydrochloric acid. However, polymeric materials are generally weaker and softer; less resistant to concentrated sulfuric and oxidizing acids and solvents; and subject to temperature limitations.
