ABSTRACT
The review article provides test methods for pipe steels in environments containing hydrogen. The authors analyze test procedures designed for determination of pipe steel properties to provide further estimation of their serviceability for transmission of hydrogen-containing natural gas. The fatigue properties of the pipe metal decrease with increasing hydrogen content in the gas mixture. The method of determining the of the fatigue crack growth rate is promising for pipe metal in gas mixture containing hydrogen.It has been established that hydrogen impacts gas mixture compression. This fact should be taken into account when selecting operation modes for compressor stations.
