VALDuotherm GREEN PPR Pipe D. 90×15.0mm SDR6 L4m

VALDuotherm GREEN PPR Pipe D. 90×15.0mm SDR6 L4m

SKU: 10013090019 Category:
The VALDuotherm PP-R SDR 6 pipe is utilized for indoor cold and hot water supply installations, as follows:
- Class 1 - hot water 60°C - PN 10 bar; design temperature based on 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 based on 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 sanitary 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, which is why the effect of pipe expansion or contraction must be evaluated before wall mounting (surface mounting) of PP-R pipes. Correct installation of clamps or other types of supports and proper positioning of expansion compensators prevents uncontrolled pipe movement due to temperature variations during installation and operation. As a rule, installation expansion is compensated between 2 fixed points by changing direction, using an expansion loop, or where not possible, compensators must be fixed between the pipe and the structure. Fixing clamps (also called fixed points) of the installation are positioned near branches, valves, or wall penetrations, while sliding clamps are mounted along the installation route at well-defined distances. This ensures installation alignment, support, and controlled axial movement. When installing PP-R pipes in screed or walls, they must be placed in protective tubes with a flexible, well-insulating structure capable of absorbing pipe expansion. In case of excessive expansion that is difficult to compensate with the insulating protective tube, an expansion compensator must be calculated and installed. Please note, pipes must be installed at an acceptable depth under the screed or inside the wall to avoid cracks; furthermore, excessive internal stresses at joints must be avoided. The installation depth must be greater than or equal to 1.5 × the outer diameter of the tube. Threaded joints are not permitted in screed or walls. The pressure test is performed before final burial of the pipe/installation.

The technical manual addresses methods for evaluating expansion and ways to compensate for it, including clamp positioning.
