Study on corrosion law of NBC platform chemical agent pipe
At present,there are few studies on the internal corrosion of the chemical agent pipes.Therefore,based on the on-site operating conditions of NBC chemical pipeline,this paper adopted the weight loss test and electron microscope to observe and analyze the corrosion law of chemical pipes,to understand the internal corrosion status of NBC drug pipes.The uniform corrosion and localized corrosion of NBC pipes under different temperatures(20、70℃)and pressures(0.63、3.72 MPa)were studied.Through the test,with the increase of temperature and pressure,it is found that the rate of uniform corrosion and localized corrosion increases gradually,with the product dominated by iron oxides.
