hey guys I got my last section of boom stuck solid any advise on how too best clear it out !!!

Maybe a pressure washer in the end? It depends how old the mud is.

Use a forklift and remove the pipes. Set one end of the pipe on the ground and lift the other end into the air and drop it ( make sure nobody is standing near by ). Then pick the pipe up and empty it out. Continue to do this until the pipe is clean. We had to clean some pipes on one of our other pumps and this worked well plus it didn't chip the paint.

And if the above does not work

They make great fence posts,ballards,conversation pieces.

we use with rock drill here

find your nearest hydroblast company and see what they will do it for, 1 section they can clear in 2-3 hours

 Pressure washer + blow out cap...

Was that hardened concrete? Cool, never thought a pressure washer be that powerful!

 Some times it pushes out the dual wall insert and it obviously wont work for elbows!

 Hey butcha, boom pipe full of concrete is called a "Boom Party". When it's hose that's called a "Line Dance", When it's solid stone hard those are called "Fence Posts" HA,Ha,ha...

JUST BUY SOME NEW ONES LOL

Trade-in pipe. LOL

You could also just put 6 pipes full of concrete on a flatbed, cover it with scrap steel, and go to a recycle place and hope you don't get caught.  They're paying $100 a ton, and the magnet will still pick the pipe so it's tough to tell what you did until after you have the cash.
