How high? Theaded couplings? Adding 10' sections to 1 1/4 pipe

Thank you for the previous answers that have been provided. I have a 4' diameter turbine mounted on one 10' section of 1 1/4 thick wall water pipe. I would like to go higher by adding perhaps one or two more 10' sections of pipe. I remember reading that threaded couplings are frowned upon but a search turns up nothing. Any guidence on using a threaded coupling? Is one coupling to many? I dont have access to a welder...yet. Thank you, bsafe

Here is a story about a 10 foot mill on a 1.5 inch short pipe, and it wasn't enough... http://www.fieldlines.com/story/2008/6/20/04423/6376 W o o f -={(

Has anyone flown a 4' diameter mill on a 20 foot mast made from two pipes? How did you join them?

There is pipe and then there is tubing.  Your pipe is measure by its internal clearance.  Your tubing is measured by its external displacement.  Generally the tubing is much better built than the pipe for the same advertised "size". ----------------------------- Go Huskers! [ Parent ]
