摘要
无溶剂液体聚氨酯应用于3PE管线补口在国外已有20年以上的历史,机械化补口至少有16年以上历史。本文详细介绍了国外补口的类型及其防腐层结构特征、性能,同时也介绍了国内该技术的研究进展。
The solvenfless liquid polyurethane (PU) coating has been used abroad as a field joint coating on 3LPE pipelines for over 20 years and the liquid PU field joint coating application by machine has been used for over 16 years. The paper describes the details of the abroad field joint coating types and the coating structure and performance. The domestic research progress of the field joint coating is described too.
