Damaged pipe?

Unread postAuthor: pat123 » Tue Oct 02, 2007 2:40 pm

my uncle found a 7ft piece of 4inch sch40 on the side of the road and brought it for me. i was wondering if it is safe to use since it probably fell of of a truck going like 50 mph.

thanks,
pat

Personally I wouldn't. I dropped a barrel on my garage floor, pretty hard once. About 2 months later my buddy was shooting it and the barrel exploded. It was 2" sched 40 pvc. It wasn't the thousand fragment grenade people describe. It broke into 6 sharp edged, good sized pieces, the furthest of which only flew about 15 feet. Don't know what happened to the potato. Oh, and my friend got a little cut on his arm. It wasn't bad, but I still wouldn't want it to happen to me. I wouldn't use it. Just me though.

yeah I probably won't use it. I have had a pipe blow on me before too but it wasn't because of dropping the pipe it was because of me and my friends stupidity. we made a dry ice gun out of cell core. it left a 2inch deep hole in my garage wall and a cut on my leg.

I'd use it, its perfectly fine for combustions, maybe pneumatic, but how would you know that it fell from a truck, its not like it was pressurized and more vulnerable
I'd be more concerned with UV damage is the pipe at all yellowish compared to true fresh white pvc

Make a big ass combustion, is there any hairline cracks? If not it should be ok. If used in a pneumatic with your 2"piston valve don't crank the pressure. 100psi max. Be safe good luck.

Yeah, Agreeing with the masses here. You could risk it. I think it could work for your average "Spay n' Pray" (to use JSR's wording :wink: ).

But after a while it would start failing. Definitely don't recommend it for a pneumatic or hybrid or Advanced Combustion.

I'd use it, I've dropped 4" pvc sch 40 pipe off my roof and some blew of my car when I was taking it home and I still use dit in combustions and pneumatics with no failures yet. If you're really worried just use it for a big combustion.

I guess the resident old guy here (being me) is being over-cautious. . .
