The role of a Coating Inspector has evolved considerably over the past few decades, and the responsibilities have increased over what used to be a rather straightforward job: to verify that surface preparation and coating application meet the project specification requirements. Today there are week-long or multi-week basic and advanced coating inspection courses, specialty courses that are industry-specific (e.g., bridge, nuclear), courses that are substrate-specific (e.g., concrete coatings inspection) and even coating-specific (e.g., inspection of thermal spray coatings).
Case studies of corrosion under insulation (CUI), identifying the key contributory factors within each example and discussing the limitations of the first pass desktop approach. Experience has verified that intimate knowledge of the system in question can greatly increase the probability of success and reduce risks.
Third-party paint inspection contracts provided an immediate, tangible benefit in supplying a qualified, certified coating inspector full-time to a painting project. Inspectors could be rapidly deployed and provided someone to the project with broad experience in painting projects; however, simply providing a third-party contract paint inspector to a project did not always ensure the project was completed properly.
In November 2011 a 5 month old baby unfortunately got killed in a Dutch swimming pool because 2 speakers and a speaker frame landed on her head. This paper will describe how this accident could happen and what has been done in the Netherlands since 2001 when the entire ceiling and airchannels came down in another swimming pool (luckily this occured during closing time).
Simulation shows that navigation algorithms can guide autonomous vehicles to inspect poles or towers for corrosion, or to inspect enclosed spaces. The algorithms use sensor feature extraction, PID control, dynamic window obstacle avoidance, and genetic algorithm solutions to the traveling-salesman problem.
RLs are susceptible to internal corrosion that is influenced mainly by fluid corrosiveness including factors such as temperature, pH, carbon dioxide (CO2) and hydrogen sulfide (H2S) content, water chemistry, flow stagnation, wettability, and presence of deposits.
Generally, for corrosion to occur there must be liquid water with sufficient quantity to wet the pipe surface. Once water wet, the line will corrode at a rate determined by the chemistry of the water, acidity and quantity of deposits.
