A Method to Measure the Soil Corrosive Rate of Pipe Material

Based on the resistance method, a method to measure the soil corrosive rate of pipe material reliably is established through improving measuring technology in the paper. This method possesses the following characteristics: (a) a larger sample may be used; (b) a steady corrosive rate can be obtained in a short time and the measuring precision up to 0.3 microns is very high and (c) both general and local corrosive rate can be measured and analyzed using this method.
