SDR 35, PS ³ 46 psi

judging from the markings taken from this table.

Residentral sewer line, my cousin works with this all the time. He's a foreman for Comer Construction, Forest Hill, Md. Runs a utility pipe laying crew. Develeptments/commerical sites. Uses a lot of copper line when running house connections in new developments, 3/4" i think.

do any of you guys think i could use it for a combustion gun chamber? it would be great if i could cause then i could just take the pipe and no one would notice

P.S. thanks for the table link ill use it!

Rated to 46psi, I'd say no. A metered propane combustion gun can theoretically produce 82-86psi, this is too much of a pressure spike for pipe rated to 46.

Though there's continual debate on the topic, I prefer cellular core ABS for combustion guns - if it DOES fail, it rips clean with no shrapnel (as far as my testing can tell...). It's also dirt cheap.

NSF-PW PVC is always considered the best.

Peace,

i have seen sewer pipe used before, but it was rated to more PSI than that. I would not use that low rated pipe. Combustion makes alot of pressure too, i wouldnt risk it. JMO

do you have an air compressor. if you do put a chuck in a small piece of the pip and hook the air compressor on it and turn it on hiding behind a wall and if it blows up don't use it if it doesn't you can.

hey i dont garbage pick i just wanted to know if i could save money on pvc but i guess i cant. and i wouldnt do that with this pipe ill use some other pipe it sounds fun. i just want to blow up a peace of really good pvc.

[super spuder]

hey. i told him to get behind a wall. i would do any time the time to test pipe

[hi]

i would bet that if the combustion chamber was only about 8 inches or so and had a coupler in the middle it would be ok, but probably not worth it.

[Specialist]

nah im not even going to use the stupid sewer pipe everyone says its bad. but super spuder's test project sounds fun

Yeeeah, let us know how that goes -- if you still have your hands.
