Understanding Pressure Pipe Networks

Gravity system designs and pressure system designs are quite different and must be addressed using different tools. For a pressure pipe network design to be a success, it must meet the following basic requirements:

• The bends and curves must be constructed according to industrystandard fittings and allowable joint deflections.
• The pipes must be sized according to specific flows and pressures.
• The pipes must be far enough underground to avoid being damaged by freezing or by activities on the site.
• The pipes must not be so far underground that it is cost prohibitive to install them.
• Appurtenances such as valves and hydrants must be included in the design to allow the lines to be controlled, accessed, and maintained.

These requirements relate to three basic types of pressure pipe design components: fittings, pipes, and appurtenances. This discuss describes these components as well as their relationship to each other when represented within a Civil 3D pressure network.
