The invention relates to a slow tensile test method of pipeline steel in a hydrogen environment, belongs to the technical field of pipeline steel testing, and solves the problem that performance testing of the pipeline steel in a high-pressure hydrogen environment is difficult to realize in the prior art. The method comprises the following steps: S1, mounting pipeline steel of a test sample into a hydrogen environment box; S2, filling the pipeline steel in the hydrogen environment box with hydrogen; and S3, connecting the pipeline steel filled with hydrogen into a slow stretching instrument, and carrying out a slow stretching test. Performance testing of the pipeline steel under different hydrogen partial pressure conditions is achieved, the pipeline steel is always in a hydrogen environment in the testing process, and then the testing accuracy is guaranteed. 本发明涉及一种管线钢在氢气环境中的慢拉伸试验方法，属于管线钢测试技术领域，解决了现有技术难以实现在高压氢气环境下对管线钢进行性能测试的问题。本发明通过步骤S1：将测试试样的管线钢安装到氢气环境箱中；步骤S2：对氢气环境箱中管线钢进行充氢；步骤S3：将充氢后的管线钢接入慢拉伸仪，进行慢拉伸试验。本发明实现
