Smart pigs, for example, have continued to grow in popularity and are playing a key role in detecting stress cracking, and general and pitting corrosion, with their highly tuned sensors...

.... This monitoring may involve the use of witness coupons and the use of sensors which will measure temperature, relative humidity, irradiation, microbial activity, etc. Sensors need to be specially developed for nuclear waste monitoring since the measured changes may be small, but the performance time...

... on the cathodic protection criteria of carbon steel and stainless steel was investigated in intermediary (1020 m depth) and deep water (2020 m) at the same location. For this purpose, at set of corrosion and environmental sensors, as well as metallic coupons, were exposed during 11 months in Azores...

... ABSTRACT Permanently- and temporarily-installed ultrasonic sensors have been used in refineries for over ten years. Advances in capability, deployment and reduced size and costs have led many facilities to augment their routine thickness data-collection means from a fully-manual fleet...
