Aluminum Pressure Rating

[bjbrokaw]

Anyone have a list of pressure ratings for aluminum piping?

[CS]

mcmaster.com has this kind of stuff. They have pressure ratings, dimensions, wall thickness, etc.

[bjbrokaw]

Also, how do I thread the ends on the aluminum pipe scence I can't weld it?

[dragon finder]

You can weld aluminum it is just very hard.

[bjbrokaw]

I dont have the equipment or experience to weld it so can't I just thread it with a hand pipe threading set and some clamps?

whit a outher thead maker:D srry duno how you call it in englis

were r u from? maybe if you are from holland i can tell it dutch:D

[dragon finder]

I think they are called dies not to shure my self. I do think that you can thread alimunum. Depenting on how large the pipe is it can be easy. I think if you go to a home depo or some other large hardware store like that they can thred it for you.

if the wall thiknes is thik enough it would work. buth you must look out becaus aluminium is verry easy to unthread so 1 rotation to mutch and all the thread is gone! thats 1 thing you must remember. i know this becaus i'v got metal working on skool

[bjbrokaw]

... so screw it together very easy with some plumbers tape? and about what wall thickness do you recomend?

[taz22]

duno what is the size of the thread? in mm plz

[bjbrokaw]

I don't know. I was looking at this kit to get for making the threads. http://www.northerntool.com/webapp/wcs/ ... _200243574

[taz22]

i mean the sizes of the tube

[bjbrokaw]

Iono, diff diamiters but the tube I found on mcmaster is .120 wall thickness and I don't think thats thick enough for threads. Right?

[Shrimphead]

Definately not, that's less than 1/8th of an inch. If you want to thread it, let alone put pressure in it, get thicker pipe.

Edit
I just took a look at my ruler and I realize that 1/8th of an inch isn't that thin, but probably still to thin for threads.

[bjbrokaw]

ya i think i need 1/4 inch
