Head losses in PVC-O pipes

The main purpose of the hydraulic dimensioning of a pipeline is to determine the diameter of the pipe. The basic design conditionings are the required flow rate and the pressure required at the endpoints of the network. In addition to this, other factors such as the design speed or the head losses (continuous and localized) are also involved, as well as the characteristics of the materials of the network (roughness and cost, mainly).

TOM®, suitable pipes for the transportation of potable water

The water quality circulating inside the TOM® pipes is kept completely unaltered, thanks to the fact that it is a chemically homogeneous and corrosion resistant material, that is to say, without interior coatings or protections, so that there is no degradation of the pipe nor migrations of products from the pipe to the water.

For these reasons, and for its exceptional technical characteristics, PVC-O is a suitable material for the transportation of water for human consumption.

Hydraulic calculations for the design of networks

Any design project for a water transport or distribution network is based on the determination of a need for hydraulic supply (Qh) at one or several consumption points.

In the case of transport between two points, there will be a need for a certain flow at the outlet point that matches the flow along the entire network (Qt). However, in the case of a distribution network with several consumption points, there will be different flow rates along the network depending on the mesh, flow rates and consumption points (Q1, Q2,…Qn).
