Minor and Major barrel length for 20" pipeline receiver
Minor and Major barrel length for 20" pipeline receiver
(OP)
Gentlemen
The minimum length for a 6-inch launcher barrel should be 6 feet. For each pipe size above 6-inch add 1 foot (i.e., 8-inch should be 7 feet, 20-inch should be 12 feet, etc.)
I found the above statement while going through a search for a 20" Pig Launcher minor and major barrel length for intellegen pigging. Does this statement hold any ground, I have doubts. I could not found the length of 20" intellegent pig tool even on TDWillams site. The tool length can leads to the length of minor and major barrel. Can anyone guide me?

The [major] barrel should be long enough to accommodate normal pigs (6-7 ft is fine).
I recently saw an adaptation that I really liked. Some clever fellow put a set of flanges between the outboard pipe support and the closure. That allows him to unbolt the flange and drop in a pup long enough to accommodate a really long smart pig (and allows him to build the pup AFTER he knows the length of the smart pig he's going to run). This seems like the best of all possible worlds, wish I had thought of it. Building a launcher long enough to run smart pigs is not a great idea because it is really a pain to get a pig seated in the throat when the throat is 15 ft into the barrel every time you need to run the pig. Your shovel handle isn't long enough and it is hard to get enough force on the pig at that distance to make sure it starts.

Just don't forget to do the same on the receiver as well.
