- 摘要:
- 针对埋地泡沫夹克钢质管道几年来的腐蚀情况，加以理论分析，提出埋地泡沫夹克钢质管道不宜搞阴极保护。延长埋地泡沫夹克钢质管道寿命的根本措施是提高泡沫夹克的制造质量和施工质量，防止泡沫夹克进水。
Based on the corrosion status of underground steel pipelines coated with foam jacket in recent years, the author gives theoretic analyses on the corrosion in this article, and expresses his opinions that the cathodic profection can not suit for the underground steel pipeline coated with foam jack-et. The important measures are to increase the servies life and thermal insulation efficiency of un-derground steel pipeline, control the fabrication and construction quality of foam jacket and im-prove the waterproof property of foamcket.1989,3(3): 12-14 收稿日期：1988-10-4参考文献：
