Countermeasures Avoiding Brittleness Risk on Large Volume Seamless Steel Cylinder

At the beginning of this century, large volume seamless steel cylinder made in China, has substi- tuted the imported products and occupied the domestic market. Otherwise, it is stepping into the international market and global top 8 industry gas companies. Among the fluids contained in the cylinder, the important parts are hydrogen, natural gas and other gases with brittleness risk. This article has described the details how to avoid the hydrogen brittleness, what should we do to make some countermeasures with material, design, construction and examination of cylinder.
