Experienced with cold rolled sheet steel panels used outdoors in process plant facilities, many engineers in the oil, gas and petrochemical industry prefer stainless steel panels to eliminate the corrosion issues. If some corrosion or other advantages exist with CRCA, please differentiate with...
I can access the ASTM and ASME standards but cannot find a standard for steel sheet gage and thickness. A standard exists that cross references sheet metal gage and the nonimal thickness with tolerances, etc. Perhaps this only applies to steel and a different standard applies to stainless, ...
In iPilot.com, http://ipilot.com/forum/message.aspx?pid=77910, a pilot questions the situation with the testing. A bird strike is a major concern for many pilots. Myth Busters tested a trashed airplane windshield. It failed, exponentially and to several powers. I mean it was real bad.

Another engineer was speaking of a wing when talking about the wings on an airplane. His thought was that some aircraft have a single wing structure instead of wings attached to a fuselage. He mentioned the 747. Surely not. What if any airplanes have a singular wing structure with the...
Saturday my son took the fundamentals of engineering exam. He advised that he did OK on most things and saw a few things that he had no clue. For those taking the exams, what did you see that was a surprise?

I am looking for something similar to the portable clamp on ultrasonic flow meters suitable for measuring the branch flow for 79 psig nitrogen distribution. Most of the ultrasonic meters found are for liquid. The meters that might work for gas are permanent and need gas higher than 100 psig...
Startup operators use nitrogen to inert vessels and piping during the initial startup operations. Some amount of air would normally remain in the equipment during this process. We have a number in mind and plan to use a number smaller than that. However, we need an authoritative and...
In addition to field calibration equipment during instrument loop testing we are using a laptop PC, a Wonderware workstation and a handheld terminal for the GE Genius IO. It appears that we need an additional handheld terminal for the Genius. Is there another way to set ranges etc. on GE...
On an offshore platform, we have a run that is about 110 meter to connect a various PLC equipment in a machinery area with a master workstation and assorted items in another area. The communication exists with copper cable running 10 MHz Ethernet. We would prefer to run 100 MHz. However...
