| Note: Out-of-straightness is ordinarily checked at points of maximum deviation (as determined by line-of-sight observation) by means of a three-front straightedge and feeler gages. When overall straightness in entire length is of concern, the tube is rolled on a surface-plate and maximum deviation-from-straight is determined by means of feeler gages inserted between the tube and plate at point of maximum departure. If rotational methods such as chucking the tubs at its ends or supporting the ends on rollers and rotating under a dial indicator are used, extreme care in interpreting results must be employed because readings are influenced by OD dimensional variation in addition to deviation-from-straight.

The above table is based on the best known and most widely used formula for calculating the bursting pressure of tubes, namely Barlowís:
P=2St/D
P = Internal pressure in p.s.i. S = Fiber stress of tube in p.s.i. t = Wall thickness in inches D = Outside diameter in inches
| The table (S = 10,000) affords easy calculations with appropriate multipliers shown below. For theoretical bursting pressures, use tensile values. For theoretical bulging pressures, use yield values. Working pressures will vary depending upon safety factors required for environmental conditions involved as determined by your design engineer and appropriate codes. | Material | Tensile (Multiplier) | Yield (Multiplier) |
|---|---|---|---|
| 6061-T6 Aluminum | 42,000 psi (x 4.2) | 35,000 psi (x 3.5) | |

| Annealed 18-8 Stainless | 75,000 psi (x 7.5) | 30,000 psi (x 3.0) | |
