Classification and information on design of plastics piping systems used for renovation
|Publication Date:||1 March 2010|
|ICS Code (Pipeline components and pipelines in general):||23.040.01|
This International Standard defines and describes families of techniques for the renovation of non-pressure and pressure pipelines through the use of plastics pipes, fittings and ancillary components. For each technique family, it identifies areas of application from the range covered by existing renovation product standards, which include underground drainage and sewerage, and underground water and gas supply networks.
This International Standard provides information on the principles of, but not the detailed methodologies for, the design of plastics piping systems applied as linings to existing pipelines, covering:
- existing pipeline and site conditions;
- lining system functions;
- structural performance;
- hydraulic performance;
- other factors affecting lining system selection.
It does not cover the calculation methods used to determine, for each viable technique, the required amount of lining material needed to secure the desired performance of the renovated pipeline.
