When it comes to particulate matter, the finest particles of lead, arsenic, chromium and other regulated substances are believed to produce the largest environmental and epidemiological hazards, in terms of their ability to be dispersed broadly by the wind, and…
The integrity of pipelines, valves, vessels and other components made from carbon steel and other metal alloys depends on the material composition being exactly the same as specified, since excessive levels of trace elements, such as chromium, copper, nickel, molybdenum,…
An introduction to the Victaulic Vortex 1000 fire suppression system will be presented on Tuesday from 3 to 3:30 p.m. in Theater A. The system is the world’s first hybrid nitrogen and water system, and claims to offer a completely…
