西江定向钻穿越管道外防腐层保护的经验探讨

Explore on The Outer Coating Protecting Experience of The Directional Drilling Crossing Pipe in West River

随着城市燃气管网建设不断增加,水平定向钻穿越的应用越来越广泛。如能在地质条件复杂、穿越难度大的工程中保护穿越管道的防腐层不受损伤,将会延长管道的实际使用寿命,从而减少通气运营的压力及运营费用的投入。在实际应用中,通过分析保护材料及保护方式,选择了性价比高的实施方案。本文将从使用环境,价格对比、施工工艺等方面对西江定向钻穿越管道的外防腐层保护应用经验进行探讨。

With the increasing construction of city gas pipeline networks, the crossing of horizontal directional drilling is used more and more widely. If the crossing pipe coating is protected from damage in the project with complex geological conditions and great crossing difficult, the life of pipeline will be prolonged, the operating pressure and operational costs will be cut down. In practical application, the best cost-effective scheme was selected through the analysis of protective material and protection. This paper was written to explore the application experience of the outer coating protects of the directional drilling crossing pipe in West River project from the factors such as the environment, price comparison, construction technology.
