Abstract

One of the main factors in determining pipe diameter to design of potable water supplying systems is the flow velocity. The design flow velocity cannot be chosen above a certain value since higher velocities cause deterioration of cement mortar lining, additional management costs and destructive water impact.The flow velocity limits noted in the literature are given in a specific range (0,5-3,0 m/sec). However, the mentioned velocity limits can be increased up to a certain value in systems without pumping by decreasing the pipe diameter. Better quality of cement mortar used in the interior lining of the pipes help to increase capacity and thus the cost of the project can be reduced. In this study, an experimental pipeline model was set up from ductile pipes with cement mortar lining in which high velocities were aimed and a series of experiments were conducted. Experimental set up was composed of ductile pipes with four different diameters (Ø200300-400-450 mm) and water was recycled from a reservoir to the pipe system and back to the reservoir by pumps. The measured thicknesses from the pipes were compared and the changes on the cement mortar lining were observed
