Abstract

Die Erfindung betrifft ein Verfahren zur Erzeugung einer inneren Zinnschicht an der Oberfläche von aus Rotguß oder Messing bestehenden Installationsbauteilen für die Trinkwasserversorgung. Erfindungsgemäß wird zunächst der Bleigehalt an der inneren Oberfläche der Hohlbauteile durch Behandlung mit einer wässrigen Reduktionslösung auf Säurebasis verringert. Hierbei kommen chlorid- und sulfatfreie nicht oxidierende Wasserstoffsäuren zur Anwendung. Anschließend werden die Hohlbauteile chemisch innenverzinnt.
