Abstract
The invention refers to a lining device (15) for a plate heat exchanger, a plate heat exchanger, and a method for manufacturing a plate heat exchanger with a package of heat transfer plates and an end plate (5), which has at least one porthole. The lining device includes a first part (16) and a second part (17). Each of these parts is manufactured of a sheet metal and has a substantially cylindrical pipe portion (16a, 17a) and an abutment portion (16b, 17b). The pipe portion of the first part is introducible in the porthole and the pipe portion of the second part is introducible in the porthole into the pipe portion of the first part in such a way that an area (19) is formed where the pipe portions overlap each other. The parts are connected to each other by a weld joint (18). The material thickness of the first part is greater than the material thickness of the second part at least at the overlapping area.
