| titleOfInvention | High density polyethylene piping |
| abstract | A high-density polyethylene pipe capable of safely transporting a fluid containing a high concentration of a radioactive substance for a long period of time even when used in an environment where both ultraviolet rays and radiation are loaded. A high density polyethylene pipe (1) has at least two layers of an inner layer (2) through which fluid flows and an outer layer (3) covering the outside of the inner layer (2) and containing 1 to 3% by mass of carbon black, The inner layer 2 and the outer layer 3 are both formed of a base material containing polyethylene having a density of 0.940 g / cm 3 or more and 0.980 g / cm 3 or less, and at least the inner layer 2 is generated when crude oil is refined. % of ring analysis by n-d-M method of oil C n is 20 or more and 60 or less of oil containing naphthenic, and percent of ring analysis by n-d-M method of oil occurring when purifying the crude C a is the to contain as additive at least one of the oils containing 5 or more and 40 or less of Aromatics.
