摘要
介绍了管道电预热施工工艺的基本原理、施工方法及施工中要注意的问题。该工艺与传统的管道预热安装方式相比,管道预热升温快,施工占地少,且对环境无污染。
The paper introduces basic principles of pipe electric preheat and the method of construction and some problems that need to be considered. Comparing with traditional pipe preheat install pattern, the pipe electric preheat can preheat faster, use less space and won't pollute the environment.
