REFERENCE NOTES
Burst pressure estimates are based on using Barlow’s Formula.
*Barlow’s Formula is expressed as:
Tubing – (2 * MTS * t)/d for estimating theoretical burst pressure.
Pipe – (2 * MTS * t)/D for estimating theoretical burst pressure.
For tubing, outside diameter (D) can be substituted in the calculation for a more conservative value, however the use of inside diameter (d) has been proven valid. The end user should determine the appropriate working pressure and safety factor for the specific application given all relevant operating conditions.
- MTS = Minimum tensile strength (psi)
- MYS = Minimum yield strength (psi)
- t = Nominal wall thickness (inches)
- d = Nominal inside diameter (inches)
- D = Nominal outside diameter (inches)
Working pressure = 1/4 of theoretical burst pressure
Pressure ratings are based on 100° F operating environment only
** Theoretical yield pressure is the point of permanent deformation and calculated by substituting the MYS value in the equation.
*** Collapse pressure estimate shown is per API 5C3 calculation. Formula: (2 * MYS * (D/t – 1)) / (D/t)2
Weight per foot calculation = (Outside Diameter – Wall Thickness) x Wall Thickness x Grade Density Constant
