煤气管道带压带水焊补漏点技术在济钢的应用

摘要

As leaking points in the complicated gas pipe network of Jinan Steel are greatly varied in sizes, shapes and locations, many leakages which are difficult to repair have forced users to stop production to treat the leakages, bringing economic losses. To solve these problems, Jinan Steel probed the method of repair welding of gas pipeline leakages under pressure and with water. The operation essentials and attention points of the method ware summarized.%济钢煤气管网错综复杂，漏点的大小、形状、位置也不尽相同，很多焊补难度较大的漏点不得不迫使用户停产配合处理，带来了经济损失。针对这些问题，济钢探索了煤气管道带压带水焊补漏点的焊接方法，概述了此方法的作业要点及注意事项。
