环氧玻璃钢外防护层技术在长江定向钻穿越中的应用

Application of Protective Coating Technology Outside Epoxy Fiberglass in Directional Drilling Crossing Project of Yangtze

在大型江河的定向钻穿越工程中,如何加强对穿越管道防腐层的有效保护是穿越管道施工和后期安全运行的重要环节。以环氧玻璃钢外防护层技术在长江定向钻穿越中的成功应用为例,介绍了该技术的性能特性及施工工艺、检验方法,为后续大型江河定向钻穿越工程的设计和施工提供参考。

In the directional drilling crossing projects of large rivers, how to effectively protect the anticorrosion layer of crossing pipeline is the important link of the pipeline construction and safely operation. Taking the successful application of protective coating technology outside epoxy fiberglass in directional drilling crossing project of Yangtze as a example, the characteristics, construction technology and test method of the protective coating technology outside epoxy fiberglass are introduced, which can provide the inference for the design and construction of the directional drilling crossing projects of large rivers.
