Estudo de viabilidade técnica e econômica da utilização de tubo PEX em residência

Abstract

This study addresses the technical and economic feasibility of adopting PEX pipes in homes, comparing them with conventional pipes. The objectives include the analysis of the technical and economic characteristics of PEX (cross-linked polyethylene) pipes. The work begins with the presentation of the context, objectives, justification and methodology. In the theoretical foundation, residential hydraulic systems, types of pipes, characteristics of conventional pipe and PEX pipe, and previous studies on the use of PEX pipe are explored through a literature review. The methodology applied, through a literature review, encompasses data collection and comparative analysis of conventional and PEX pipes. In the technical analysis, we sought to investigate the technical properties of conventional pipes and PEX pipe. In the economic analysis, the costs of materials, installation, maintenance and useful life of the materials were considered. Based on the results and discussions presented, it is concluded that the use of PEX pipes in homes provides several advantages over conventional pipes. PEX pipes offer greater installation flexibility, corrosion resistance, lower maintenance requirements and longer service life. Additionally, economic analysis demonstrates that, in many cases, PEX pipes are more financially viable in the long term. These conclusions highlight the effectiveness and substantial benefits of using PEX pipes in residential contexts.
