摘要
介绍了预制直埋保温管道无补偿电预热安装的应用领域、安装原理以及对保温管道的要求。对安装工艺及施工方案进行了探讨,列举了施工中的注意事项。比较了无补偿电预热与热风预热、热水预热工艺,电预热具有一定优势。
The application field of electric preheating installation without compensation for prefab- ricated directly buried insulating pipe, the installation principle and the requirement for insulating pipe are introduced. The installation process and construction scheme are discussed, and the matters needing attention in the construction are listed. The electric preheating without compensation is compared with hot wind preheating and hot water preheating, and the electric preheating has an advantage.
