摘要
阴极保护对“管中管”管线起不到完全保护作用,这是由“管中管”防腐保温材料的性质及其结构上的特殊性所决定的。解决“管中管”防腐问题的关键是保证补口质量,只要补口不漏水,“管中管”结构的管线可以考虑不加阴极保护。
The method of cathode protection can not totally protect the pipeline if pipe-in-pipe typcbecause it is limited by the performance of anti-corrosion and insulation materials and their structural characteristics of pipeline of pipe-in-pipe type.The key point of anti-corrosion for this type of pipeline is to ensure the quality of pipe patching coating.It is considered that the cathode protecting may mot be necessary for this type of pipeline as long as there is no water leakage in the patching area.
