FEP & PFA Burst Pressure Calculations

Formulas for the approximate burst pressure of tubings over temperature.

Approximate PFA 451 tube burst pressure value may be calculated by the following formula:

BP=[2278-(3.77)(T)][(OD/ID)-1]

• BP = Burst Pressure at specified temperature
• T= Maximum Temperature of the Fluid in the Tubing, ºF
• OD = Outer Diameter of Tubing, In.
• ID = Inner Diameter of Tubing, In.

NOTE: This formula is only valid for temperatures "T" between 0ºF and 500ºF.

Approximate FEP tube burst pressure value may be calculated by the following formula:

BP=[1929-(4.29)(T)][(OD/ID)-1]

• BP = Burst Pressure at specified temperature
• T = Maximum Temperature of the Fluid in the Tubing, ºF
• OD = Outer Diameter of Tubing, In.
• ID = Inner Diameter of Tubing, In.

NOTE: This formula is only valid for temperatures "T" between 0ºF and 500ºF.
