In the plant "Purina" the water for production is taken from a well. Originally they used carbon steel pipes to transport the water, which were useful only for a year, then they had to change the pipes since they suffered serious corrosion problems. This phenomenon happened due to the high sodium content of the groundwater. The customer required a flexible pipe with a longer service life than carbon steel pipes to maintain a stable operation and minimize sudden stoppages for maintenance operations. They decided to supply a pipe of 110 mm diameter in a single section which can withstand without any inconvenience the weight of the pump, the cables, the water column and the weight of the pipe.
