It is important to measure the extent of corrosion. According to the results of TV detection and analysis, you can quantify the degree of corrosion, estimate the corrosion rate, predict the service life of the pipeline, and establish the database required for the pipeline corrosion prediction model. The easiest way to measure the degree of corrosion is to remove the corroded part of the pipe and measure the thickness of the corroded layer. But this method is very inaccurate and needs further correction. Other methods include remote sonar technology and TV detection technology, etc. These technologies are more accurate, but the equipment is expensive. The specific measurement method to be used will be decided after a cost-benefit analysis. The corrosion prediction model can predict the corrosion degree and corrosion rate, as well as the service life of the pipeline. The predictions made by theoretical models are generally not accurate and need to be corrected based on the data collected. The classification of corroded pipelines is based on site survey data and corrosion prediction models, and can be classified according to the extent of pipeline corrosion to determine the objects to be reviewed. Pipelines with very severe corrosion need to be repaired; if the corrosion is not too severe and can still be used normally, prevention and control of pipeline corrosion is required. Corrosion control and repair requires corrosion control of the corroded pipeline. If the corrosion only occurs on the surface of the pipeline, and no structural damage occurs, then the corrosion can be controlled manually by controlling the generation of HZS, which costs much less than repair. On the contrary, if the corrosion is severe, the inner surface of the pipeline is severely penetrated, and the structure is obviously damaged, the repair of the pipeline needs to be considered. Corrosion control-reduce sulfide concentration By reducing the concentration of dissolved sulfide in sewage, hydrogen sulfide corrosion can be controlled. Common control techniques include: oxidation method, precipitation method and pH method.
