The average lambda values for different types of LOGSTOR pre-insulated pipes are presented below. These lambda values are used for calculations of heat loss from LOGSTOR pipe systems.
Type of pipe | Actual lambda value
- Straight pipe, axial conti production | 0.023 W/mK
- Straight pipe, traditional production | 0.027 W/mK
- Straight pipe, spiral conti production | 0.025 W/mK
- FlexPipe | 0.022 W/mK
- Fittings | 0.027 W/mK
- PUR insulation in foamed casing joints | 0.028 W/mK
- PUR insulation shells for casing joints | 0.036 W/mK (after 30 years' aging)
