Hey Alex303,
More concerned about the high stresses on joints and possible failure on due to axial stresses. I'm thinking at some point the length will be so large that the pipe will stretch out like a piece of bubblegum and snap. However, I can estimate that using the material data available...
To help prevent line for freezing in winter, they completely drain the line during the winter months...careful operation procedures when they start it back up in the spring thaw. This pipeline is for mine dewatering and mainly for storm water events.
Once again cvg is correct, the ease of...
Hey Guys,
CVG is correct in that Constructablility is a concern. So in my opinion Aluminum is not the answer.
I'm in agreement with CVG that intermediate supports and/or pumping is a more likely better option.
For Miningman,
Currently the client (location in Northern Ontario, Canada) is...
Sometimes I use some string with weighted ends to throw the string around the pipe to measure the OD the pipe.
Of course depends on the what the pipe is carrying....
Sometimes I can read a valve model no or flange/pipe marking which has the dia.
Hey Engineers,
I have a pump at the bottom of an Open Pit Mine (similar to sketch attached) that's going to discharge water up the pit wall to the nearest pond. Based on the Pump Size I can calculate the required thickness for the HDPE Pipe. However, I'm concerned with the fact that currently...
Just an update I searched "propane emissions factor" and I found a link from the US EPA that maybe of use to others.

Greetings,
I'm trying to find a reference/rule of thumb to determine how much CO2 and/or CO is formed after propane combustion in heating coils (in Air Handlers and Unit Heaters). An example of a unit heater I am using is Modine Model PTS. This is for my list of emissions into the environment...
Indeed! Most of the time though when we find the problem we tag it first then inform the maintenance crew and they repair it. Can't always steal maintenance's job.
Thanks for your input guys,
I think I'll get the miners to complete a tour of the mine during a shut-down to find leaks. Maybe find a summer/fall student to do it for me to save on cost ;-). I'll talk to corporate to get an incentive going...I'm sure they will do it since compressed air leaks...
Greetings,
First time poster....I hope this is the right location to post. :)
I have a Underground Compressed Air System (max psi 100) feeding various areas in a 1000m deep mine. Think of it as 10" Victaulic Piping "spidering" everywhere around the Underground Area.
I know it is impossible to...
