SCI's London Regional Group and the Institute of Corrosion - London Branch
co-sponsors supporting this event include the Institute of Materials, Minerals and Mining (IOM3), The London Materials Section (LMS), and the Welding Institute (TWI)
This event is no longer available for registration.
This free evening event includes two presentations, the first on the historical background of electricity, the second, a report on the recent problems of AC Corrosion on pipelines. A networking drinks reception will follow the talks.
1750 - Benjamin Franklin's Electricity Experiments: Dr Fred Parrett, SCI London Regional Group Chair & Parrett Technical Developments
Prior to the 1740s, it was 'static' electricity that people used for magic tricks by creating sparks and shocks. Scientists conducted experiments with electricity, but scientific thinking about electricity had not changed much in hundreds of years - electricity wasn't 'useful' yet. Then, around 1740, the American writer, businessman, and politician, and inventor, Benjamin Franklin became interested in electricity. Being a curious and inventive thinker, Franklin wanted to know more than just the popular tricks. Through his many well documented experiments he is rightly considered the principal founder of the scientific study of electrical phenomena. This was before the first batteries were invented and we could experiment with direct current, so all these experiments were all with static electricity. This presentation will summarise his work on electricity along with a summary of many aspect of his fascinating life, including his 18 years of living in London.
2017- AC Corrosion on Pipelines - a serious hidden problem: Dr David Eyre, Consultant
Corrosion is controlled on high pressure oil and gas pipelines by application of a high quality coating system, supplemented by cathodic protection (CP). AC Corrosion is a recently identified form of corrosion that can cause rapid full-wall penetration on coated pipelines by induced AC current, even with a fully functioning CP system. This can occur when the buried pipeline parallels overhead HV powerlines. This talk will describe how the AC is generated onto the pipeline, the corrosion mechanism and how the risk can be assessed and mitigated.
