Study Of Scaling Mechanism In Slurry Pipeline And Prevention Measures

There is more than one hundred years that pipeline transportation has been applicated. With the application of pipeline transportation expanding, scale deposit issue of pipeline has become a very importance problem that restricted the development of pipeline transportation. Scale deposit of pipeline, lightly, making pipe diameter smaller, decreasing the unit flow and not reaching the expectant demands, increasing the unit energy consumption and the unit transport costs , seriously, making pipeline plugged and scrapped that not only a tremendous impact on production, but also a huge waste of resources. Based on the serious danger of pipe scaling. Many experts,scholars and engineers who have tried to reduce the probability of scaling in pipes when they design pipeline, study objects of pipeline transportation, consider environment of pipeline laying, control parameters of pipeline transportation and so on. When the pipeline has been put into use for transportation, pipeline must be detected and removed the fouling materials regularly.Based on the results of previous studies. Understanding the fundamental nature of the object and matter fouling in slurry pipeline transportation. Analysing the mechanism of slurry pipeline scaling. And listing a number of domestic and international anti-scaling, scale removal methods. Proposing to control the flow so as to achieve anti-scaling and scale removal. Conducting a feasibility analysis of this method. Aim is to explore a method of the anti-fouling and scale removal once and for all, to achieve better development of pipeline transportation.
