Stronger Pipe? (or not)

Unread postAuthor: cannon freak » Sat Jun 10, 2006 9:07 pm

Just wondering whether an actuall PVC pipe is stronger than a pipe made out of couplings and small segments of PVC pipe. I always thought that the the plastic being melted together beceause of the solvent weld was stronger.
However I don't know, so if someone could elaborate on this please do.

The small gaps in the couplings would give it many weak spots. The PVC would simply shatter along those points specifically. Maybe, and I say maybe, you could do a 3" chamber covered in 3" couplings, sleeved inside 4" pipe. 3" fittings are said to fit very well in 4" pipe.

Dont cut the pipe, simply bore the "stops" from the couplings. I did this on my hybrid that hasnt been finished for over a year now...
