摘要
本文对于硬质聚氨酯泡沫塑料的保温层影响埋地管道质量问题作出简单介绍,主要原因为进水问题使管道塑料被腐蚀,屏蔽阴极保护电流等,并提出改善泡沫质量、优化补口技术、改进阴极保护等措施。
This paper briefly introduces the influence of insulation layer of rigid polyurethane foam on the quality of buried pipelines.The main reason is that the problem of water supply causes corrosion of pipeline plastics,shielding cathodic protection current,and puts forward measures to improve foam quality,optimize the repair technology and improve cathode protection.
