Abstract

Die Erfindung betrifft einen insbesondere zur Abwärmenutzung in der chemischen Industrie bestimmten Wärmetauscher mit an ihren Enden in Bohrungen mindestens einer Rohrplatte (4) druckdicht befestigten Wärmetauscherrohren (3) aus ferritischem Werkstoff, die in einem von einem Kühlmedium durchflossenen Wärmetauschergehäuse (5) angeordnet sind. Um die aus ferritischem Werkstoff bestehenden Wärmetauscherrohre (3) vor Versprödung zu schützen, ist zumindest im hohen Temperaturbereich der Wärmetauscherrohre (3) jeweils ein Schutzrohr (6) aus versprödungsunempfindlichem Material angeordnet, das durch hydraulisches Aufweiten im Bereich der Rohrplatte (4) im Wärmetauscherrohr (3) befestigt ist.
