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.The invention relates to a method for producing an inner tin layer on the Surface of gunmetal or brass installation components for the Drinking water supply. According to the invention, the lead content on the inner surface of the hollow components by treatment with an aqueous Acid-based reducing solution reduced. Here are chloride and sulfate free non-oxidizing hydrogen acids are used. Then the Hollow components chemically tinned.
