燃气管道法兰接口泄漏修复技术的研究

Research on Gas Pipeline Flange Interface Leakage Repair Technology

燃气管道上安装的配件用法兰连接的居多,在修复法兰接口时却需要停气断管、调换法兰,不仅费用高,且影响正常用气。采用“管道法兰快速堵漏夹套”可以解决法兰片之间的堵漏。这种结构可承受1.0MPa的压力,可用于输送各种介质、不同管径的法兰接口带压堵漏修复,造价低、操作简便。

Flange is in the majority as the accessory usage on the gas pipeline links. Flange interface repair need cut off a tube, change the flange, not only cost is high, but also influence on common gas. Adopting ＂pipeline flange quick plugging jacket＂ is able to resolve the leakage between companion flanges. Such configuration can endure 1.0 MPa pressure, which may transport various medium and repair flange interface plugging under pressure in different pipes＇ diameter. Furthermore, it＇s cheap cost and convenient manipulation.
