i've run a fair amount of gas line commercial, residential 2" is the largest i ever put in.
42" pipe 2000psi it ROASTED THE PLACE!! i mean tore that shyte UP!! just thinking how many bibles i could have burned!! they still don't know the size of the pipe but it was BIG!!!
all i can say is that's one llll of a flame thrower! that sucker makes nice big fire. wonder how much i gotta pay a guy to light that rascal, very impressive. seriously, just think of the possibilities, i REALLY like it, i REALLY, REALLY do!!
