High-density polyethylene - Wikipedia

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene.It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomeranes and plastic luer.

Absolute Pipe Roughness - EnggCyclopedia

''Relative Roughness'' or ''Roughness factor'' of a pipe is the ratio of absolute roughness to the pipe diameter. Relative roughness factor is often used for pressure drop calculations for pipes and other equipment. The relative roughness factor is an important parameter for determining friction factor based on Reynold''s nuer for flow in a pipe.
