Influence of the Accuracy of Determining the Inner Diameter of Pressure Polyethylene Pipes by the Amount of Head Loss by Length

Abstract

The article presents the results of the analysis of the requirements of All Union State standard No18599-2001 to the thickness of the walls of pressure polyethylene pipes. An example of hydraulic calculation of a pipeline made of polyethylene PE 100 with a diameter d = 315 mm is considered. It is made in two versions - without taking into account and with allowance for dimensional tolerances stipulated by the requirements of the standard. The influence of the limitations on the thickness of the pipe walls on the values of their internal diameters and hydraulic characteristics is analyzed.
