为了保证高压油气系统管线能够安全无泄漏投产,高压有毒流体、可燃流体管道在普通强度试验检验完毕后,依据规范要求必须进行泄漏性试验。采用氦氮混合气体作为试验介质对管道进行泄漏试验,利用氦气检漏仪的高灵敏度对泄漏量进行量化,能够精准地完成管道的泄漏检测。 In order to ensure high-pressure oil and gas pipelines can be safely leak-free production, high pressure toxic fluid, combustible fluid pipe in the general strength test after the test, according to specifications must be leak test. The helium-nitrogen mixed gas is used as the test medium to conduct leak test on the pipeline. The high sensitivity of the helium leak detector quantifies the amount of leakage and can accurately detect the leak of the pipeline.
