1. Enter the values for tensile strength (PSI), wall thickness (Inches) and outside diameter (Inches) into the form, below.
  2. The ‘Compute’ button will calculate the burst and working pressures using Barlow’s Equation, while ‘Clear’ will clear the form.
  3. If you do not have tensile strength for your material, please call 1-800-455-2276, and ask for technical assistance.
