Corrosion Analysis of the Pipeline for Heating System in a Apartment

아파트 난방용 배관의 부식원인 규명

The corrosion failure analysis for the heating pipeline of apartment was performed. Usually, the heating pipe was layed in the concrete. However, it was known that the corrosion problems could be induced by admixture containing chlorine such as set accelerant. antifreezer and so on. Therefore the new construction method using stone ash instead of concrete was attempt to solve these problems. However water leaking accidents by corrosion occurred after 1 month from the completion of the apartment. In this paper, the reason of corrosion failure was investigated by the field study and laboratory analysis in many aspects.
