| description | The invention relates to high-density polyethylene tubes, joints and seal materials. Specifically, the present invention provides a high-density polyethylene pipe, a joint, and a seal material that suppress deterioration due to external factors such as radiation. The high-density polyethylene pipe (10), the joint and the seal material of the present invention include: an inner layer (1) composed mainly of high-density polyethylene having a density of 0.940 g / cm3 or more and 0.980 g / cm3 or less; a gas barrier film (2) covering the outer surface of the inner layer 1 and containing an ethylene-vinyl alcohol copolymer resin; an anti-fusing adhesive film (3) covering the outer surface of the gas barrier film (2) and containing a resin having a melting point of 150 DEG C or higher; and an outer layer (4) with low-density polyethylene covering the outer surface of the anti-melt adhesive film (3) with a density of 0.910 g / cm3 or more and 0.930 g / cm3 or less as a main component.
