Abstract

Abstract

Leachate, because of its complex and harmful components, which may accelerate pipes scaling and corrosion during its collection and transportation, poses potential risk to the environment. In this study, four typical pipe materials, including steel pipe, galvanized pipe, HDPE pipe and PVC pipe, were processed into experimental samples and immersed into leachate under aerobic and anaerobic conditions, investigate their corrosion resistance. Through the analysis of the samples weight changes, combined with the characterization of material properties, it was found that the scale formations and degree of corrosion were significantly related to the samples surface roughness. The rank of the materials was as HDPE > PVC > RC > TC. This study was expected to provide useful insights into the selection of pipe materials for leachate collection and transportation, ultimately to ensure the safe operation of the landfill.
