The calculation model and selection of the strength parameters of the CIPP liner – guidelines DWA-A 143-2

Speech deals with the issues of selection suitable boundary conditions for a technical condition of the pipeline. Properly set output parameters determine the course of the design process and the relevance of the solution – in this case the appropriate CIPP liner. The leading issue is to analyze the process of determining the strength characteristics which is basis on the guidelines DWA-A 143-2. The main stage of the design process is to analyze the stability of the pipeline-lining CIPP. The basic condition which allow appropriate selection of parameters is proper assessment of the pipe technical condition. Properly executed project should ensure optimization of both the economic and construction of the proposed solution.
