DESCRIPTION:
Design
The hydraulic design of a RENOVATION VRC + pipe network involves determining the diameters of the various sections, once the respective flow rate, length, piezometric height and roughness have been specified.
The sizing criteria, described in UNI 11149, must be able to meet the maximum flow rate
required, balancing the water supply according to demand.
Distributed head losses (J) can be evaluated through an abacus that relates the flow rate (Q) and the
velocity (V) of the fluid with the internal diameter (d) of the pipeline itself.
In order to avoid overpressure and stagnation, it is recommended that the flow velocity be between 0.5 and 2.5 m/s. The
localized pressure losses, resulting from the passage of flow through fittings and valves, on the other hand, should be evaluated
according to the type as defined in UNI 11149.
RENOVATION VRC + pipes comply with the requirements of UNI 10779 for the construction of water systems
fire-fighting systems permanently under pressure (the pressure rating of the system components in this case must not
be less than 1.2 MPa).
Excavation and bedding
The minimum width of the excavation must be at least 20 cm greater than the diameter of the pipe to be contained, while the
minimum depth of burial must be 1 m measured from the upper generatrix of the pipe and in any case always
weighted on the basis of factors such as dynamic loads on the soil above or the danger of frost.
Laying RENOVATION VRC + pipes also allows for different conditions than traditional methods for pipes made of
polyethylene. However, the installation must meet the requirements of UNI EN 805 and UNI ENV 1046 standards, in
particular for the preparation of the laying bed, the preparation of the lateral fill, the choice of materials and the
compaction.
Laying RENOVATION VRC + pipes through trenchless technologies (slip lining, close fit, horizontal directional drilling,...) allows an additional level of safety of the pipe systems by virtue of the higher resistance to the propagation
of cracking compared to PE100 pipes.
