In short, the insulation not only has the traditional trench and overhead laying pipeline incomparable advanced technology, practical performance, but also has significant social and economic benefits of prefabricated pipe insulation, heat is a powerful energy-saving measures. Use buried heating pipe technology, marking China heating pipes technological development has entered a new starting point. With the further improvement and development of this advanced technology, the heating pipes buried trench and replace overhead imperative. Protection of buried steel casing pipe insulation corrosion grade shall be determined by the local soil corrosion levels. When the soil buried insulating pipe corrosive soil is high grade insulation, corrosion grade special consideration should be given to strengthen the level, when the soil corrosivity hierarchy, the corrosion level should be considered to strengthen the level of steel jacket pipe insulation, when soil corrosivity rating is low, corrosion level should consider the general level. So be sure to find out the design level of pipeline corrosion deposition section of the soil, in order to optimize the corrosion level. Cathodic protection of buried pipe insulation in metal corrosion processes are electrochemical protection method. With other buried insulating pipe corrosion process is different is that it is protected by the metal body to the applied current, thereby enabling the electrode potential shifted negatively protect the metal body, the metal lost by the atoms become ions state spontaneous attitude trend, thus inhibit corrosion is fundamental. However, this process must be carried out in an electrolyte, thus very suitable for buried pipes with cathodic protection. Cathodic protection of buried pipe insulation coating itself complement each other, the presence of coating can be greatly reduced cathodic protection current consumed prefabricated buried pipe insulation, cathodic protection and coating integrity can make up for lack of respect, and thus in safety and economic aspects to achieve the perfect combination, is recognized as the best anti-corrosion program.
