Technical Informations / Life
FCS pipe are developed for a min. 50 year service life guarantee under nominal service pressure at 20 °C as a result of performance tests under conditions specified in ISO 9080 standard.
| Properties | Test Duration | |
|---|---|---|
| sLTHS ( Mpa ) | sLPL ( Mpa ) | |
| 20 | 20,2 | 18,2 |
| 80 | 8,5 | 7,4 |
ALLOWED SERVICE CONDITIONS
Temperature Dependent Pressure Dropping co-efficient
FCS pipe system is designed according to 20 °C. Its max service temperature is 40 °C. However a continuous service is foreseen above 20 °C, below pressure dropping factors must be considered:
| Properties | Co-efficient ( fT) |
|---|---|
| 20 | 1 |
| 30 | 0,87 |
| 40 | 0,74 |
For mid-temperatures, interpolation can be made. Allowed service pressure (PFA) is calculated with below equation:
PFA = fT .fA .PN
fT :Pressure Dropping Co-Efficient
fA :Application dependent (In water conduction fA=1), decrease factor (or increase factor)
PN :Nominal Pressure
