Abstract: Briefed in the paper are the current statuses of the constructions of the linepipes for pure hydrogen and hydrogen mixed gas transmission at home and abroad,the current development situation of the technical specifications for hydrogen transport pipelines as well as storage,transport,pipeline design,testing and evaluation of pro-hydrogen materials for domestic and foreign hydrogen systems. Accordingly it is regarded that along with the increases of the strength of the material,the content of the chemical elements that easily form segregation,the size and quantity of the inclusions,and the pressure and purity of hydrogen,etc.,the sensitivity of hydrogen embrittlement increases;and the weak parts such as the weld joint of the welded pipe also increases the sensitivity of hydrogen embrittlement of the pipeline. Furthermore it is recommended that the selection of the materials for the hydrogen transmission pipeline should focus on factors concerning the steel goods,including the cleanness,the chemical composition design,controls of the non-metallic inclusion morphology,the microstructure segregation and the banded microstructure,and the coating method,etc.
