Abstract
This paper presents the results of the research carried out in order to establish the optimum technology of polypropylene pipes, analysed from the point of view of temperature, time and labour press. Analysing the values obtained in the practical samples, the graphics of variation of components after assembly were traced, decreasing the diameter of the pipe after the assembly, the parameters that define significantly the quality of the assembly. The need to address such themes derived from the fact that in the literature, in the present time there are not sufficient and relevant information with regard to the assembly of pipes and connectors of PPR, most of the information being provided by the manufacturers and they are confined to the indication of the parameters of the assembly process.
