A pipeline carrying hot water buried in volcanic soils suffered severe corrosion in several months after installation. In order to study such a high corrosion rate, a field corrosion test was made with steel pieces. Also in a laboratory, corrosion tests using the soils were carried out at room temperature and 75°C for 30 days and some other tests were made with the soils. It was found that the high corrosion rate cannot be explained as the effect of pH values, specific resistivities and humic acid contents of soils.
