ABOVE-GROUND HIGH DENSITY POLYETHYLENE

Engineering Technical Note #12 ABOVE GROUND HDPE PIPE January 2009 Page 4 of 11 From Table 1, the 100 o F (38 o C) pressure design factor is 0.78, therefore the design pressure capacity, P (100 o F) would be the allowable design pressure multiplied by the design pressure factor:160 psi. APPENDIX C-A SIZING AND CAPACITIES OF GAS PIPINGing and Table C402.4(36) for polyethylene plastic pipe are based on operating pressures greater than 11/ 2 pounds per square inch (psi) (3.5 kPa) and pressure drops greater than 0.5-inch w.c. (125 Pa). In using these tables, an allowance (in equivalent length of pipe) should be considered for any pip-ing run with four or more fittings [see Table C-A.2.2].

Estimating Hazen-Williams Coefficient for Polyethylene Pipes

Polyethylene is the predominant pipe material for trickle irrigation laterals and submains because of its flexibility and resistibility to the sun. Laboratory experiments have been conducted to determine the proper values of the Hazen-Williams friction coefficient for commonly used polyethylene plain pipes of different diameters.

The first PE pipe material used in engineering applications was Type 50 High Density PE (HDPE) with a long term stress of 50MPa. Subsequently, Medium Density (MDPE) materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth THE HANDBOOK OF TECHNICAL IRRIGATION FRICTION FACTOR PIPE SIZING (continued) 20 ft. 180 ft.
