In order to build residential, commercial and industrial installations of Liquefied Petroleum Gas (LPG) in Ecuador, the INEN 2260: 2010 Ecuadorian Technical Regulation establishes the minimum safety guidelines that must be taken into account in this type of installations. To conduct this hydrocarbon, the Standard accepts several materials of pipes, methods of union with accessories, forms of installation, which makes the responsible for the sizing and planning of this type of systems have several options to choose from when directing a determined project. This paper shows some factors that affect the selection of the most suitable pipeline for LPG systems, complying with the mandatory Technical Standard in Ecuador. The mechanical strength, hardness and weight are compared as properties of the accepted materials; execution times of pipes and fittings and finally the costs associated with materials, labor and maintenance that must be given to these systems are compared.
