I was told once to figure about $1 per inch in diameter per foot. So that being said about $20 per foot assuming approximately 5 ft of pipe somewhere around $100. I believe steel prices may have gone up since I was told this, but that should be close.
That is 20" schedule 10 if it is 1/4" thick. Looks to be fairly new pipe. Call Triple S steel tomorrow and see how much it is going for per foot new and then figure out a price from there. Lots of guys will jump on this for bbq pits.
