小口径高压管道非焊接封堵技术

Non-welding Stoppling Process of Small-diameter High-pressure Pipeline

针对小口径薄壁高压管道焊接封堵作业安全性低的问题,研制出非焊接封堵四通、封堵头等主要封堵设备及非焊接封堵施工工艺。经600多次的实践应用,小口径筒式高压非焊接封堵技术安全性高,具有重要的推广应用价值。

In allusion to the lower safety in welding/stoppling operation for small-diameter thin-wall high-pressure pipeline,non-welding stoppling cross and stoppling head as well as stoppling process are developed.More than 600 times field uses display that the non-welding stoppling technology is available for safety operation and has a significant spreading and application values.
