For indoor cold and hot water supply installations, as follows: – Class 1 (hot water 60°C) – design temperature relative to service life: 60°C/49 years + 80°C/1 year + 95°C/100 hours. – Class 2 (hot water 70°C) – design temperature relative to service life: 70°C/49 years + 80°C/1 year + 95°C/100 hours.
VALDuotherm GREEN PP-R PIPE D. 32×5.4 mm SDR6 L4 m
VALDuotherm PP-R SDR 6 pipe is used for indoor cold and hot water supply installations, as follows:
- Class 1 - hot water 60°C - PN 10 bar; design temperature for service life: 60°C/49 years + 80°C/1 year + 95°C/100 hours;
- Class 2 (hot water 70°C) - PN 8 bar; design temperature for service life: 70°C/49 years + 80°C/1 year + 95°C/100 hours;
- cold water PN 20 bar at c =1.5 and PN 25 bar at c=1.25 (Informative - In accordance with ISO 15874-1 - the design pressure for domestic cold water installations for a period of 50 years at a temperature of 20 °C is 10 bar).
The linear expansion coefficient of single-layer PP-R pipes is α = 0.15 mm/m K; therefore, before wall mounting (surface mounting) PP-R pipes, the effect of pipe expansion or contraction must be assessed. Correct installation of clamps or other types of supports and correct positioning of expansion compensators prevents uncontrolled pipe movement caused by temperature variations during installation and operation. As a rule, system expansion is compensated between 2 fixed points by changing direction, an expansion loop, or, where this is not possible, compensators must be fixed between the pipe and the structure. Fixed clamps (also known as fixed points) for the system are positioned near branches, valves, or wall penetrations, while sliding clamps are installed along the system's route at defined distances. This ensures system alignment, support, and controlled axial movement. When installing PP-R pipes in screed or walls, they must be placed within protective pipes that have a flexible structure, offer good insulation, and can absorb pipe expansion. In cases of excessive expansion that cannot be adequately compensated by the insulating protective pipe, an expansion compensator must be calculated and installed. Please note, pipes must be installed at an acceptable depth beneath the screed or within the wall to prevent cracks; additionally, excessive internal stresses at joints must be avoided. The installation depth must be greater than or equal to 1.5 times the pipe's outer diameter. Threaded joints are not permitted in screed or walls. The pressure test must be performed before the final burial of the pipe/system.
The technical manual addresses methods for evaluating expansion and ways to compensate for it, including clamp positioning.
