简介了4起盛装混合气体的钢质无缝气瓶爆炸事故,通过调查分析,得出爆炸的原因:随着瓶体应力腐蚀裂纹的产生和不断扩展,瓶体剩余有效承载壁厚不足以承受内压而破裂。对盛装含二氧化碳混合气体气瓶的安全使用、管理提出了建议。
In this paper, four explosions of steel seamless gas cylinders containing mixed gas are introduced. Through investigation and analysis, the cause of explosion is deduced: as the stress corrosion cracking of the bottle body is produced and expanded, the remaining effective wall thickness of the bottle body is not enough Internal pressure and rupture. Proposed for the safe use and management of carbon dioxide mixed gas cylinders.
