Heating and twisting PVC pressure pipe help

[Marco321]

Hey
I did some searching and only found heating and bending pvc pressure pipe. My research on the website only showed bending the pipe and im twisting it.
My question is:
When i made my pneumatic gun i used two 90 degree elbows with some pvc pressure pipe between them. I did the elbows a little skew and was wondering if heating with the heat gun and twisting the pvc pipe streight (only about 5 degrees clockwise) will damage the PVC pipe in any way.
Thanks
Marco

I would not feel safe doing this... it could create weak spots which would be prone to failure... especially because it is a 90 degree bend rather than a straight section.

on a simple combustion i would say it was ok, but still kinda stupid.
on a pneumatic i would say that you should call the hospital and say that you will be coming in in a few hour and that you just wanted to give them a heads up.

I.E.- dont do it, just get the proper fittings.

Im not heating it and benging it 90 degrees, im heating it and stwisting the pipe a little. The pipe is still streight

[hi]

its still not smart on a pneumatic.

[Marco321]

Oh ok, why not? i didnt heat it enough to melt it, it was still touchable easily, and i only twisted it a little. I also thought pvc was a thermal plastic.

[hi]

all im saying is that i personally wouldnt do it. if its the barrel then its fine, but the chamber its not such a good idea simply because if you bend it that means that you are streching the plastic on one side and smushing it together on ther other. i know its not a whole lot, but it will weeken it a little and i just dont think its the best idea in the world thats all.

[Marco321]

Im not bending it, im twisting it, so it should not be smushing it on one side and stretching it on the other side, just twisting it anbout 5 degrees. I also just had a google search and there are machines and stuff for bending pvc pipes and they all don't say anything about dangers, unless thats only for pipes not under pressure.

An easy altearnative would be chopping off the elbows and replacing them with street elbows. Then you can twist and turn them any way you like.

[Marco321]

I have the elbow fittings on it and everything, its just the pipe connecting the 2 elbow fittings which i had to twist so the barrel and the chamber where parallel, i twisted the pipe about 5 degrees across its cylindrical surface

Go out and try it.
Do it remotely

[Marco321]

Iv already done it, i did it because i couldn't see any reason not to. I haven't shot it yet because i thought i should ask you all here. Its a ball valve so i cant do it remotely. But what im asking is does heating pvc damage it? I don't think it does because its a thermal plastic. I also didn't put any bends in it, just a twist. The tube i twisted is about the width of an average mans hand.

it doesnt matter reforming the pipe WILL weaken it personally i think ur nuts which would you rather do spend $5 and chop off the fittings and try again OR pay thosands of dollars to get all the pvc shcpnel removed form ur body?

[Marco321]

Ok
How do i remove the pipe?
