    The aim of this research is to study the electro galvanizing of zinc or electroplating of Zinc, on the inner surfaces of R-1 3/16 couplings manufactured by Impofreico S.A. By means of a factorial experimental 2 to the third power design, varying parameters of the coating process, such as; the arrangement of the couplings, the agitation of the electrolyte and the immersion time, in order to determine the incidence on its quality of anti-corrosive protection under the INEN 1176 standard. To obtain the optimum levels of the electrolyte for the electrodeposition, a Hull cell was use. From the results obtained, it was established that the optimum working parameters are at a temperature of 20 Celsius degrees and with a current density of 2.7 ampere per square decimeter. After the experiments, it was observed that the arrangement of the couplings inside the electrolyte is the most determinant in terms of coating of the zinc layer of the internal surface of the samples, providing a good anticorrosive protection to the elements of study. Likewise, after the cost analysis to implement the equipment for the process, it was determined that the return on investment would be in 18 months and from that date the economic savings for the company will be 40 percent.
