Such piping systems must be rated for both internal and external pressures at the given temperatures.

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.
