Purpose: The present study outlines the advantages of using trenchless methods for the rehabilitation of pipelines made of steel, concrete, cast iron etc. The authors describe causes of carrier pipe ageing and methods of their inspection and renovation. The technical aspects of choosing the renovation methods are also presented. The paper includes a decision-making flowchart for choosing the carrier pipes renovations. Design/methodology/approach: The 1980’s and 1990’s saw an explosion of new pipe installation and repair techniques which minimize the need to dig continuous trenches to bury the pipeline, so called ‘trenchless technologies’. The trenchless technologies have been widely applied for the rehabilitation of various pipelines such as sewage systems, gas pipelines or water supply systems. There has been characterized the swagelining technology which is based on one of the metal working technologies and namely the sinking of pipes. Findings: The PE pipe stress in the drawing die zone has been analyzed and an attempt has been made to analyze the mechanisms causing the elastic recovery of PE pipes. There have also been presented the diameter changes as the parameter of the elastic recovery which is a result of our own research conducted in accordance with the program developed. Research limitations/implications: Each pipeline renovation method has its advantages and disadvantages, possibilities and limitations, depending on the application. Practical implications: The work is an example of analysis of chosen trenchless renovation on the example of swageling technology. Originality/value: The trenchless renovation of pipelines certainly will be more readily used in the future because of wearing out of pipelines. The other reason is the lack of space for new utilities, increasing costs and road-surface restoration requirements.
