So I have read all the threads throughout the site about using 30 gauge pipe for dust collection. Most are older and full of "advice" from people whom either do not use or never had ill effects first hand with 30 gauge ducting.

Can people who have it in their shop or who have used it and it failed please chime in. I will be running a system that in total will have around 100 feet of pipe and I am thinking of using 6" 30 gauge pipe. The dust collector will be a Shopfox w1687, 3hp, 2800 cfm, with a 55 gallon drum separator.

Anyone have a similar system? Is there any reason to worry about the piping collapsing if the blast gates are closed?
