Results of the research aimed at the development of the basic criteria and principal methodological approaches to the calculation and design that underlies any repair undertaking associated with the restructuring of engineering networks through the application of a polymeric sleeve. It is noteworthy that the pipeline material and the degree of its deprecation, identified on the basis of the residual pipe thickness, the length and the diameter of each pipeline section being repaired, the media pumped into the pipeline, the adjacent ground and subterranean infrastructure, the presence of any subterranean waters and other factors are to be considered in each specific case.
A software programme designated for the calculation of the durability of double-layer structures of pipelines connected to polymeric sleeves has been developed. The software makes it possible to consider a wide range of properties of a polymeric sleeve to identify its behavior driven by any alterations in the input information, and to select the most economical and technologically efficient option within the limits imposed by the durability-related requirements pre-set in the design.
The ultimate objective of the software programme is to assess the applicability of the trenchless repair method involving a polymeric sleeve in each specific case by taking account of the environment and the condition of the pipeline. The software is also capable of developing the requirements to be fulfilled by subcontractors in order to assure the appropriate quality of any repair work performed and the reliability of any pipeline sections repaired.
