为了避免油气管道工程整体式绝缘接头发生泄漏,结合其结构特点,对可能发生泄漏的部位、通道以及泄漏情况进行了分析。在此基础上,为避免绝缘接头发生泄漏提出了预防建议:在出厂前应该对内部每个部件进行严格的设计、验证及质量控制,针对设计工况采取避免泄漏的方法,可以保证绝缘接头密封性能。研究结果对绝缘接头的设计、制造、成品试验及安装具有一定的指导意义。 In order to avoid the leakage of monolithic insulating joints in oil and gas pipelines, the possible site of leakage, passageway and leakage were analyzed according to its structural features. On this basis, in order to prevent the leakage of insulation joints proposed a precaution: the factory should be rigorous design, verification and quality control of each of the internal components, for the design conditions to avoid leakage to ensure that the insulation seal performance. The results of this study have certain guiding significance for the design, manufacture, finished product testing and installation of the insulation joint.
