The utility model relates to the technical field of PE product production, in particular to a high-density steel lining PE three-way connector device which comprises a metal pipe body and a high-density PE lining layer, the metal pipe body is of a three-way connector structure and is provided with a flange, and the high-density PE lining layer is welded in a hot melting mode and covers the inner surface of the whole metal pipe body and the end face of the flange. A protective plate is arranged at the intersecting line of the metal pipe body, the protective plate is fixedly mounted at the intersecting line of the metal pipe body through a first stud and a nut, and the protective plate covers the high-density PE lining layers of the two cylindrical surfaces adjacent to the intersecting line by a fixed width. According to the three-way connector device, the corners of the high-density PE lining are protected through the protection plates, the phenomenon that the lining layer is excessively abraded or stripped fr
