Corrugated Polyethylene Pipe

Single wall corrugated polyethylene pipe is used primarily for drainage applications, and to a lesser degree, for conveyance of storm water. The corrugations of small diameter pipe are usually concentric, whereas larger diameters may be concentric or spiral wound. Various characteristics of corrugated polyethylene pipe are described, including such physical attributes as material, available sizes, standard lengths, protective linings and coatings, joints, and fittings. Performance characteristics include allowable internal pressure, external load capabilities, hydraulic resistance factor, wave speed, allowable leakage rates, and water quality tolerances. Installation and maintenance criteria include specifications; tapping methods; repair methods; installation, backfill, and protective requirements; and useful life. Information about common standards, industry groups, and reference publications is also included.
