# Burst pressures of various metals (pipes / tubes ) ??

[insert favorite cursory introduction here];
I'm looking for any method or tables for evaluating burst pressure ratings of various metal pipes and tubes.
Of interest is a comparison of strengths of metals, and how to evaluate burst pressures of pipes and tubes at high temperatures.
Thanks !

PR/2T = Stress in pipe wall ( perhaps 1/4 of the tensile strength or less)
P= pressure R= pipe radius T= wall thickness
YOu might guess that comparing by strength is a pretty good idea.
You might suspect that picking materials with good elevated temperature strength would be a good idea for elevated temperature pressurized pipes.
You might like to imagine that any material can be made into a useful pipe, but cost becomes an issue especially if that material isn't already commonly made into a pipe.

Hi Jim,
Does that equasion work with "thick walled" cylinders (cylinders with a thickness greater than 10% of its outer diameter)?

What does your book on "Mechanics of Materials" say about the simple equation (for a thin walled cylinder)?

From Formulas for stress and strain by Raymond Roark (forth edition)
chaptor 12 (pressure vessles;pipes)
case 72 If the walls of the vessel are relatively thin (less than about one-tenth the radius) and have no abrupt changes in thickness, slope, or curvature, then under uniform pressure and at points remote from the ends, the stresses s1 and s2 are practically uniform thruoughout the thickness of the wall and are the only stresses of importance present, the radial stress s3 and such bending stress as occur being negligibly small.

Pressure vessel standard, table giving high temperature properties of tube materials?
