摘要
管道内防腐挤涂工艺，可使4～5km管道内涂层一次施工，消除了单根管内涂敷后铺设需逐一补口的麻烦，具有操作简便、灵活、适应性强等优点，适于现场作业，提高了防腐效果，并可延长管道使用寿命1～2倍。
The inner coat of 4~ 5km length of pipe can be painted in one time of construction when theextrading and coating.process for inner anticorrosion of pipe be applied.Overcoming the troubleof pipe joint coat one by one after each'pipe is welded into whole pipeline,this process has advan-tages in simple operation and conviniece construction and is suitable for field spotoperation.Furthermore,the process vaises anticorrosion effect and extends pipe's survice life in l~ 2times.
