The results of studies of local hydraulic resistance in polypropylene segmental elbows (R/d ≤ 1) and bends (R/d > 1) in systems of two or more pipe fittings connected in series are analyzed. Qualitative and quantitative formulas for the coefficient of local resistance in pipelines built from elbows and bends connected conformingly (forming spiral loops) or alternatinvely (forming sinusoidal waves) are presented.
