Yay!! Free golf ball barrel!

Unread postAuthor: elad311 » Wed Oct 22, 2008 9:19 am

Today, my father was going to throw my little brother's pool to the dump,
but I saw that one of the pipes looks like a 2" one, so i took it..
i did check the diameter, but it wasn't 2" it was a little bit smaller,
i tried to put a golf ball into it, and it fits right in!

so now, i don't know if i should use it for a combustion or for a pneumatic.. :?

Does say on the pipe if it's pressure rated? The only pipe that is would say SDR 21 or 26 (200 or 160 psi) and still be golf ball size.

Beware kiddie pool plastic pipe!

Really, just to sleeve it, I would use the SCH-80 conduit pipe they sell at home depot, or normal SCH-40 with spacers made from duct tape. The conduit is not pressure rated, but really all you are attempting to do with sleeving is keep the SDR-21 from flexing too much, causing a failure. If held straight and rigid, the SDR-21 has it's own pressure rating of about 200 PSIG, which would be perfectly acceptable for any pneumatic or combustion you'd be making.
