Bursting at the Seams

Often times a device manufacturer will need a tube to withstand a given amount of pressure before exploding. Each application requires a unique amount of pressure and Zeus is here to help solve the problem. Zeus materials have varying properties and the calculation of burst pressure depends several factors.

In order to determine the theoretical number you will need: Inner Diameter, Outer Diameter, and Material Tensile Strength. A list of tensile values is below.

Tensile Strength Values:

* PTFE - 2,500 psi
* FEP - 3,000 psi
* PFA - 4,000 psi
* ETFE - 6,500 psi
* PEEK - 13,000 psi

The equation can be found here and it does not factor in steam pressure, altitude, etc., and it is calculated at ambient room temperature. The Burst pressure result is meant as a guideline in design, not a definitive number.

Please contact Zeus to evaluate samples of our extruded tubing or request a quote. To locate regional distributors, contact a technical account manager at 1.800.526.3842 or 1.803.268.9500.
