When designing a heat exchanger system, engineers must consider ways to control and mitigate the many different kinds of fouling. These control plans must be reviewed on a case-by-case basis for each unique environment.
Laboratory testing using biofilms can provide a reliable means to evaluate the potential for microbiologically influenced corrosion (MIC), and subsequently, to assess the effectiveness of biocides to inhibit biofilm growth and mitigate MIC during hydrotesting and wet parking.
River Scour Monitoring (RSM) systems, through the use of temperature sensing, have proven effective in detecting exposed pipe and the degree of pipeline scour. Identifying scour early on is key because once a pipeline is uncovered, it can be damaged in multiple ways. To avoid pipeline operator liability, and keep people, the environment, and related resources safe, it is important to follow applicable regulations and codes.
Led by Dr. Mehrooz Zamanzadeh, technical director and principal investigator at Matergenics, this roundtable discussion explores the need to conduct corrosion risk assessments of infrastructure after exposure to wildfires.
The Lafayette tank in Lancaster, Pennsylvania, USA, is a 7.5-million-gallon reservoir for potable water. USTP was given a rather tight timeline for such a large project. Photo courtesy of Induron.
The Belenus condition sensor utilizes an ultrasonic pulse-echo to provide in-service monitoring of pipe wall thickness. It can be fitted to structures including pipes, storage tanks, and pressure vessels.
When the failure occurred, Tucson Water employees were in a hurry to figure out what their next steps would be. This article details the failure, the remedial actions, and the proactive approach they've taken since.
Materials Performance (MP) magazine is proud to introduce a new class of winners from the 2021 MP Corrosion Innovation of the Year Awards program.
The repair was designed with a prediction of 100 years of service life extension. This was achieved with a steel coating and a concrete coating (barrier effect) that produced a similar or better protective effect than recorded during the evaluation.
In this case study, investigators found that a buried log or root had likely affected the exterior coating on a ductile iron waste pipe. None of the inspections prior to the rupture, which spilled nearly 15 million gallons of untreated sewage, had caught the damage.
Corrosion can be a significant challenge for refiners in downstream operations, and one of the key factors in causing corrosion in crude distillation unit overheads is hydrochloric acid (HCl).
The chloride concentration effect in naphtha on the corrosion behavior of carbon steel was studied by simulating conditions within naphtha hydrotreating unit equipment.
Twenty-first century x-ray technology has allowed University of Warwick scientists to peer back through time at the production of the armor worn by the crew of Henry VIII’s favored warship, the Mary Rose.
A review was carried out on the impact of corrosion on offshore platforms, vessels, and structures in the Trinidad and Tobago Atlantic Ocean environment. This article analyzes carbon steel coupons placed at different points on steel piles.
The authors studied open-cell aluminum foams with different pore densities under marine conditions, with the objective of learning more about the corrosion behavior of these materials. The resulting deeper understanding is expected to lead to expanded utilization in advanced engineering applications.
