Blb, I didn't know that you speak french. I'm in my second year. And I agree, you speak well Cpt. Rollhart. To connect your pipes and fittings, try to find pvc glue and primer. Put the primer on first, then the glue, then put the pipe in the fitting.

Try and use the information on this forum and other web sites in a translator to help you with things and you shouldn't require the nails/screws.

Link for translations if needed.The whole wed site is now in French.

<a href="http://translate.google.com/translate?u=http%3A%2F%2Fwww.spudfiles.com&langpair=en%7Ces&hl=en&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools">LINK</a>

NOTE FROM PIMPMANN22: Link was edited because it f*cked the layout of the page. Please go back and check future posts for such problems.

EDIT:Fair enough.I thought it would work,ohh well.

RNA_duelers, such automatic translating programs typicaly output somewhat messed up text - although I'v used them sucsessfully to read russian sites before. (was rather frustrated by the diagrams - which being an immage, could not be translated...)

As to the captain's question, yeah, 120 psi should be fine. (no garantees, but that's the nature of gas systems)

ok thank you every body but I still have another question ...

Can I screw an air gauge in a 4" diameter PVC pipe with teflon without any escape and a good result ?

yeah but do be careful with putting an air gauge on there, you will need to tap your hole (which requires a special tool set)

to tap it you need to use plumbing taps, not standard screw taps

when you put the teflon tape on wrap it tightly around the threads in the opposite direction of the threads otherwisse it could come loose as you screw it on.

no you dont need to tap it, you only need to drill a hole just smaller than the pressure gauge, it will tap itself, also only tap where the fittings overlap.

I am very confused, I went to my local hardware to look for PVC pipe and fitting. I asked to the salesman How much psi these PVC pipe can support. He answerd me 12-15 psi ?!?!!?!? WTF ? this is the weight of my cat !!!! That was black PVC fitting ....The only Pressure rated PVC part I saw was a PVC ball valve ... I asked him what kind of pipe can support about 150 psi. He showed me some cup pipe ...

Can anyone explain me how does it work and where can I find some GOOD pvc pipe ?

Yeah good PVC pipes are quite hard to get in europe. Try using copper. Even though its more expensive i think its worth the price. You can then go up to 200psi without any trouble ;) When I first got the idea of using copper I thought it would be difficult to work with, but I was wrong. It's realy easy as long as you have a simple gas burner that you can buy in any hardware store, flux and solder =) The welding part is easy. I have never welded any kind of pipe in my life and I was surprised how clean and nice the joints on my copper cannon turned out.

I'm thinking to buy larger copper pipe so I can make a chamber for my 1" sprinkler valve 8)

He lives in Cannada not Europe,maybe you could order some from the USA if u needed some pressure rating,or just go to a different store in a different town/city and ask them.

the black pipe is ABS and id not pressure rated it is used for drains. the whits should be Pressure rated, check for a XXXPSI printed on the side, it should also say NSF PW as long as it says thoes it is pressure rated =and should be the onty thing you use. if it says coex cell or Not For Pressure dont use it.

Also for the guage you need to tap it into a joint where the plastic is twice as thick. you should just tap it. a 1/4 inch tap is $6-8 and well worth it

Well, at least you got a honest salesman... they have a tendancy to lie and say that drainpipe (the DWV stuff rated to 12-14 psi) is fine for pressure.
Which it's not, and occasionaly we get someone injured when it blows up.

Questions:
Where did you go to buy the pipe?
What do you mean by "cup pipe"? Copper pipe, drinking water pipe...?
