Abstract

The function between free corrosion rate of pipeline steel and soil resistivity was set up and verified using 127 data of free corrosion rate and soil resistivity from home and abroad.The results show that the free corrosion rate of pipeline steel and the logarithm of soil resistivity have an inverse relationship approximately in neutral and alkaline soil.The data of free corrosion rate follow the Weibull distribution.When the soil resistivity decreases,the distribution of corrosion data becomes more scatter.The free corrosion rate of pipeline steel in acid soil is greater than that in neutral and alkaline soil with the same resivitity.
