摘要

Method of manufacturing a metal lining for a plate heat exchanger and a metal lining manufactured according to this method. The method comprises plastic machining of a smooth plate (10) such that a cylindrical part (30) and at least one edge flange (31) is formed. The metal lining comprises at least one cylindrical part and at least one but preferably two flanges (41, 44; 51, 52).
