Burst pressure represents the mechanical strength limit of your tubing; it is the pressure which exceeds the tensile strength of the tubing material. Thus, burst pressure determination incorporates the tensile strength of the tubing polymer as well as the tubing wall thickness. Note, however, that polymer properties – including tensile strength – vary based upon resin grades. Therefore, the burst pressure calculated here is approximate.
Burst pressure, P, is calculated based on the following formula which uses approximate tensile strength values, T, of the polymer:
To calculate the approximate burst pressure for your Zeus tubing, enter the outside diameter (OD) and inside diameter (ID) dimensions of the tubing (in inches) in the spaces below. (Note: OD must be larger than ID). Also shown in the calculation results is a working pressure based upon a 4:1 safety factor.
