A methodology of experimental research on hydrogen embrittlement of pipe carbon steels due to the transportation of hydrogen or its mixture with natural gas by a long-term operated gas distribution network is presented. The importance of comparative…
Currently, the periodic inspection of composite tanks is typically achieved via hydrostatic test combined with internal and external visual inspections. Acoustic emission (AE) technology demonstrates a promising nondestructive testing method for…
Nowadays, we can choose a carrier bag made of traditional LDPE or a biodegradable polymer to pack vegetables, bakery products, and other products in more and more shops. However, the customers and the selective waste collection system are not yet…
The effect of hydrogen on the mechanical properties of X70 welded joint was investigated in simulated natural gas/hydrogen mixtures at 10MPa. The hydrogen volume fraction was set as 0, 5.0 and 10.0vol.%. The slow strain rate tensile test showed that…
