Evaluation of the impact of production tolerances on pipes made of polymer materials on the energy demands of pumping units

Summary

A comparison of the hydraulic potential of pressure water and wastewater pipelines made of polymeric materials is given. The values of production tolerances on the pipe wall thickness and their nominal outer diameter should not necessarily be taken into account while choosing the characteristics of pumping units for these pipelines, since the discrepancy in the energy consumption of pumps under the specified feed conditions does not exceed 0.11%. While designing pipelines made of polymer materials, it is proposed to take into account the value of the actual internal diameter of the pipelines, which ensures the accuracy of selecting the pump.
