摘要
由于节能减排的要求,清洁能源天然气快速发展。在燃气管道的施工与维护中,传统的技术停气维护周期长、成本高、容易出事故。现在的双封双堵技术,即不停输开孔封堵技术不仅降低了平均停气时间,而且更加节约环保。双封双堵技术具有推广价值。
On account of the request of energy conservation and emission reduction,clean gas develops quickly.In the construction and maintenance of gas pipelines,the traditional technology of gas shutdown maintenance cycle is long,which has high cost and is easy to produce accidents.Now the double sealing double plugging technology,in other words,the sealing technology of continuous transmission hole not only reduces the average gas stopping time,but also saves the environment.The technology of double sealing and double plugging has the popularization value.
