O impacto do uso da tubulação de multicamada (PEX) no custo de instalação de gás GLP

Abstract

The choice of the type of piping for the LPG gas distribution network in residential developments influences the budget for building installations and, as a result, directly impacts the entire cost of the development. The comparative evaluation between budgets such as the use of multilayer piping (PEX) and other types of materials available on the market, allows identifying and defining which materials are economically more advantageous. The present work aims to evaluate the use of PEX multilayer piping and the budgetary impact that its application provides. The results obtained demonstrate the positive impacts on the cost of material and on the hiring of labor. The work also demonstrates the importance of designing the project, which allows the prior definition of materials and compatibility with other existing facilities, thus ensuring greater technical quality, generating greater safety, economy, shorter execution time and reduction of rework.
