Experimental Study on Dynamic Corrosion of Qingdong 5 Sewage Pipeline

A corrosion loop experiment device was designed, reactor dynamic test and loop dynamic test were carried out respectively. The results showed that under the same test conditions, the corrosion rate of the test piece in different environments increased in order as follows:the test piece in the reactor, the test piece of the inner wall of the loop pipe and the large test piece of the loop.The corrosion of the test pieces was uniform corrosion.
