Abstract: 
The current text refers to a study developed to evaluate the mechanical behavior of concrete pipe prototypes, manufactured with steel fibers added in different contents, such as: 10 kg/m3, 15 kg/m3, 20 kg/m3, 25 kg/m3 e 30 kg/m3, replacing the conventional reinforcement. Also, simple concrete and reinforced concrete pipes were manufactured to allow a comparison among them. The pipes had nominal diameter and length equal to 600 mm and 1.5 m, respectively. These types of pipes are commonly used in water rain drainage systems. The steel fibers used have an aspect ratio of 75 and present the following characteristics: 60 mm medium length and 0.80 mm medium diameter. The results show that the application of steel fibers for concrete pipes provides a very good mechanical behavior, since the ideal addition for each kind of concrete is studied. Therefore, the addition of steel fibers to concrete pipes is an innovative technology that goes out laboratories to pipes factories.
