Electrochemical Studies of 316L/20G Clad Pipe Weld Joint Corrosion Behavior

Abstract:

To research the corrosion of clad pipe weld joint, commenting the welding processes of and analysis of the corrosion medium of clad pipe weld joint, using electrochemical impedance spectroscopy carried out the comparative analysis of Nyquist and bode diagram within the time limit of clad pipe weld joint. The results showed that: 316L/20G clad pipe weld joint in the sewage water up to two weeks, because of the passive film thickening, weld corrosion resistance up to the maximum, and then stabilized; Its resistance is slightly decreased, but still has a good corrosion resistance, therefore, 316L/20G clad pipe can be widely used in the sewage pipelines of oil and gas fields.
