Article bred to apartir of the work of conclusion of course for attainment of heading of Bachelor in Civil Engineering 1 INTRODUCTION the System of Flexible Tubing of Polietileno Reticulado (PEX) is an installation of pipes in semiflexible plastic material, that serves for the hot and cold water distribution. The PEX substitutes other hydraulical systems with praticidade and better performance. Used wide in the Europe and brought for Brazil for the Astra company, this solution was adopted successfully in enterprises already delivers. According to BARBI OF BRAZIL (Barbi of Brazil – Pipes and Connections PEX: catalogue. So Paulo. 3 P.) Reticulao is a chemical process that the thermoplastic polyethylene suffers during the process of manufacture of the pipe, transforming into a new material that we start to call reticulado polyethylene or PEX abreviadamente. This new material possesss characteristics of resistance to the pressure and the very superior temperature to polyethylene normal". The PEX in such a way brings advantages for constructor how much for the user.
For working with hoses instead of pipes, the system diminishes the use of connections to make the great majority of the curves of the tubing. They are characteristics that add in quality and praticidade. The prensagem between connections provides to durability to the installations, guaranteeing a bigger estanqueidade. The maintenance is very lesser, and excuses the necessity to break walls to find the pipe defective
