大容积钢质无缝气瓶致脆风险的防范措施

Countermeasures Avoiding Brittleness Risk on Large Volume Seamless Steel Cylinder

本世纪初,国产大容积钢质无缝气瓶,逐渐取代进口,占领国内市场,并进军国际市场。钢瓶盛装和运输的气体当中,一部分是氢气、天然气等具有致脆风险的气体。国产钢瓶如何在质量上、安全上占领优势,让国内外客户放心,如何防范钢瓶的氢脆,在钢瓶的材料、设计、制造、检验等方面有哪些措施,本文进行了较详细的论述。

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.
