Study of the relationship between the nature of wells water in Libyan southwestern zone and the occurrence of corrosion in the transferring metal pipelines

Abstract

ABSTRACT: In the south western of Libya, groundwater is transported by metallic pipes from wells to the consumers for drinking, domestic, agricultural and industrial purposes. By the time, most of these pipes have faced various cases of internal corrosion which caused economic losses and leakage of quantities of transferred water. The area of study is located in south western part of Libya (Murzuq basin). Chemical properties of samples from 45 wells were collected and analyzed. Results showed higher concentrations of O2 and CO2, normal values pH, and traces of H2S. The internal corrosion of the metallic water pipelines in the district was related to the effects of high levels of O2 and CO2.
