Plate heat exchanger with connection pipes lined with bellows

A plate heat exchanger (1) comprising:

• a package (3) of heat transfer plates (2) provided with inlet and outlet ports (4), said ports forming channels through the package (3) for at least one heat exchange fluid,
• two frame plates (6) between which said package (3) of heat transfer plates (2) is mounted such that an outer heat transfer plate (14) of the package (3) is situated adjacent to one of the frame plates (6), at least said one frame plate (6) having at least one through hole (8), which communicates with one of said channels,
• at least one connection pipe (9) firmly connected with said one frame plate (6) around its through hole (8), and
• at least one tubular lining (10), which by means of a permanent connection (13) is connected to said outer heat transfer plate (14) around one of said ports (4) and which extends through said through hole (8) and said connection pipe (9), the lining (10) being arranged with room (12) for radial movement in the connection pipe (9),
• wherein said lining (10) is provided with at least one bellows (11) having folds adapted--upon relative displacement between said one frame plate (6) and said outer heat transfer plate (14) in a direction across the connection pipe (9)--to facilitate bending of the lining.
