Pipe networks transporting hydrogen pure or blended with natural gas, design and maintenance

Steel is subject to hydrogen embrittlement (HE). This problem is relatively accurate for pipes transporting hydrogen pure or blended with natural gas. Therefore this problem has to be taken into account for the design and maintenance of pipe networks for this kind of transport. Design needs to modify the design factor for computing maximum working pressure in this case. Defect harmfulness needs specific tools for each type of defect which are...
