I think that if you were able to put two and two together, you'd be able to figure it out on your own.

Nope, it's not safe for pressure. You must keep the pipe in a vacuum, as pressures above normal atmospheric will cause it to explode into millions of pieces with the force of a 100 megaton nuclear bomb.

:roll:

EDIT: Obviously you can't figure it out on your own. It's F*CKING STEEL for the love of God. Normal steel pipe has less than 1/8 wall thickness and can handle well over 500 PSI.... jeez.

Just becasue it is brittle doesnt mean it cant take pressure. And it is a bit*h to tread, just stick to the PVC, unless you can thread it.


EDIT- I looked at the pipes in my basement and they are all looks like glued to gether of a grove seal meabey.

This is cast iron pipe, so there should be no seal.

Plus, where are you gonna get a 2" NPT die? Why not hand it over to a CNC machine shop, (just JOKING!!!).

Welding is probably your easiest bet. There are plenty of people out there qualified to weld pressure vessels. They'll probably laugh at your choice of construction materials, but they just might do the work for you....

For a small fee of course.


Just stick with threaded steel pipe. Not for safety's sake but for ease of construction's sake. After you get the pipe welded, you might have been better off just buying a 2" galvanized nipple...
