煤气管道不动火、不停产带压堵漏新技术

A New Leakage Blocking Technology for Gas Pipe During Operationwith Pressure and Without Fire

南钢1999年以来有44处煤气管道严重跑、冒、滴、漏,漏点大部分需要停产检修,采用瞬间堵漏剂与低温快速固化高强度玻璃复合新技术,在不动火、不停产、带压、带水的条件下顺利施工,经济效益显著。

There are 44 gas pipes that seriously leak in Nanjing Iron & Steel Co. since 1993 and most of them need outage overhaul. In the condition of operation with pressure and water and without fire, the leakage blocking reagent and low?鄄temperature and fast?鄄solidified glass with high strength are used in construction, which obtains great economic benefit.
