Pressure testing charge pipes
 

Alright just like the title states. I'll be making my charge pipes very soon and wanted to know if there was a way to pressure test them.

I have to weld some of the bends together which could have small pinholes in them...i doubt it though exhaust tubing welds nice since its so clean.

Anyways anyone have any ideas if I wanted to do this?

the real way to do it is make a plug for one end and then make an adaptor to stick in there with an air compressor hose. then put the whole thing underwater to see if it leaks.

on mine i just coated all the welds with jb weld to seal them real good then i plugged one end and blew air in the other and put soapy water on the welds. the soap will make bubbles if it leaks.
ya it ghetto but it works for big leaks. i had none after the jbweld coating i put on there.

or u can cap the ends add a inline pressure gauge and fill up to what ever psi u wanna test and let sit over night. if empty in morning u gat a leak. u can put a pressure guage on one side and nipple on other too

We just held our hand on one end and filled it with water.

what kind of welder did you use? Arc?

Re:Pressure testing charge pipes
 

use pvc pipe plugs drill for airconnection and gauge use what ever connectors to put together

I prefer the big lumpy never gonna leak welds.

silly putty works well if u have leaking welds ;D

Thank you for some ideas guys....

and I'll be using a MIG welder I have enough experience that it should turn out alright. I'll sandblast the welds after they are done to make sure there are no pinholes...

I'll probalby try the underwater idea. Anyone know where I Could get some end caps?

pvc end caps from hardware store and whatever ur goint to use for connectors
