The Technology of Plugging Change in Gas Pipeline with High-Pressure

高压燃气管道不停输封堵改管技术是应用于燃气施工的高新领域技术,在我国还未普遍应用。本文结合合肥燃气集团有限公司燃气管道带压封堵改管的具体施工来介绍此项技术工艺。该技术解决了在役管道施工和供气的矛盾,最大限度的减少了对用户的供气影响,具有潜在推广普及的必要性。

The technology of plugging change in gas pipeline with high-pressure is the high-tech field of construction technology used in gas, which has not been widely used in our country. In this paper, the main conten is introducing the process of plugging change in gas pipeline with high-pressure Combining with Hefei Gas Group Co., Ltd. engineering. The technology having solving the contradiction between in-service pipeline construction and gas supply, and gas supply to minimize the impact on users, Avoiding the gas pipeline construction to stop the economic losses.So, The popularize of this technology is Very necessity.
