PE linings: Yep, been there, done that. A 40+ mile long line in central Georgia was being attacked by cyanobacteria which is a long word for a bug that lives in the soil and eats pyrites and poops sulfuric acid. If nothing is done about it within a few years they will perforate the pipe walls...
At the current time my role is an electrical engineer. However that means little. I've worked as a metallurgist (6 years), maintenance engineer (do everything, 5 years), maintenance manager (2 years, with dredgees and HDPE), and now electrical engineer (5 years). I'm dual degreed in process...
Surface lay, not burial. My mining engineering friends ignore funny little details like design limits. If they screw it up, it's just another day at the office. If I screw it up from the engineering department, it's the end of the world.
Need to elevate it about 4 or 5 feet off the ground to...
How to analyze to determine how much deflection should be allowed in a pipe.
Normally, obviously less is better. However I am looking at miles of pipe and trying to determine as it goes up and down over elevations when I'm exceeding design limits and need to look at providing support.
This is...
