I remember someone a while back saying they had the formula for calculating the burst pressure of pipe when given specific dimentions.

I can't seem to find the formula or remember who said it, so I need someone to post it here if possible.
If someone knows it and doesn't mind crunching some numbers, here are the pipe stats:

Metal: black iron(need a calc for steel too)
Welded seam
Inside Diameter: 2.08"
Wall thickness .166"
Thread depth: between .06 and .08
Lenght: 8.5"

Thanks.

do you mean like this http://www.engineersedge.com/calculator ... t_calc.htm

Thanks.

So what I see is, cut that # in half for the threads, and take about 2/3 that for safe working pressure. So about 792 or 54 bar.

Didn't I see a graph a while back showing DDT peaked at about 50 bar?

Edit: found it. Also posted by you

Hi,
The formula is available at http://www.engineering-alloys.com, along with other useful tools and information
