I purchased a couple of these go devils for blowing a 600' pipeline with 3 boom elbows in the system,, CF says they are made for booms,,it seems pretty tight for a straight pipeline much less a boom elbow,,, can I get some advice???

They go around those corners with no problem. When you are done the pipes are very clean.

 Make sure you use a good pig catcher at the end of the pipe,be very careful.I have seen pigs destroy a poorly welded catcher,they will literally travel hundreds of feet also going through jobsite trailer walls is a possibility.If you have problems blowing with air,clean your boom,clean your hopper,put pig in pipeline and use the concrete pump with water to clear the pipeline.

its all we use,works very well you can suckem back fast and no worries leaving buildup,one word of advice only use on new pipelines or pipelines you know or clean or you better have your blowout stuff ready buildup will cause them to hangup,but if you start out with them no worries when the pipe tings its clean
