PVC-U
I used this type of pipe for my combustion.Is it pressure rated or safe to use for pneumatics?
I can't find those SCH or grey coloured pipes.only the fittings

well, this isn't much isn't it?
A pic would be nice, or more details, I have no idea what you're talking about. Try and find a pic please.

I have yet to see a Pressure rated pvc U, and since you say its gray pipe, its a 90% chance its electrical conduit which is not pressure rated.

Well, for a combustion it doesn't have to be pressure rated, although I don't know if PVC-U is stronger/weaker than DWV.

Odd, it's the other way round here in the UK - pressure rated PVC is grey, and conduit is usually white.Killjoy wrote:I have yet to see a Pressure rated pvc U, and since you say its gray pipe, its a 90% chance its electrical conduit which is not pressure rated.
However, almost all PVC pipe is made from PVC-U (flexible PVC hoses are an exception). The U stands for unplasticised, meaning it's rigid. PVC with plasticisers in it is like a shopping bag, flimsy and less solid, depending on the percentage of plasticisers.
PVC-U tells you nothing about rating, it's just the proper name that we mean when we say PVC pipe - if you hadn't've used PVC-U, you'd've made a floppy cannon that would be unusable.
Does that thing kinda look like a big cat to you?
He might be talking about UV-PVC, which is very rare and expensive, and is available pressure rated. It resists damage from UV rays.
U-PVC is, as Ragnarok said, simply the proper name for common PVC pipe.
Any plastic pipe that is pressure rated will have some sort of a rating printed on the side of it. If it does not, it is most likely not pressure rated.

Ah I was confused, I didn't realize that he was talking about pvc material, I thought he was talking about a U shaped pvc fitting, which in America generally can only be found as electrical conduit.However, almost all PVC pipe is made from PVC-U

I use 2100kPa on a regular basis, and that'll be hiked up to 2.5MPa soon.
