Abstract
A laboratory method has been developed to investigate the gaseous hydrogen effect on the intensity of electrochemical processes on pipe steels under the action of a model medium simulating condensate at the pipe’s inner surface. It is based on the measurement of electrochemical parameters of steel under conditions of gaseous hydrogen bubbling and simulates operating conditions when hydrogen saturates a thin layer of condensate inside the pipe. On the example of API 5L X70 pipe steel significant effect of hydrogen on its electrochemical behavior under such conditions is established. It is concluded that the saturation of the model medium with hydrogen significantly accelerates the corrosion of steel and its hydrogenation.
已开发出一种实验室方法，用于研究在模拟管道内表面冷凝水的模型介质作用下，气态氢对管道钢材电化学过程强度的影响。它基于在气态氢冒泡条件下对钢材电化学参数的测量，并模拟了当氢饱和管道内冷凝物薄层时的工作条件。以 API 5L X70 管道钢为例，确定了在这种条件下氢对其电化学行为的显著影响。结论是，模型介质中的氢饱和会显著加速钢的腐蚀和氢化。
