摘要
正压式空气呼吸器的气瓶瓶体所用材料不耐氢损伤,又因制造时内防腐质量不符合要求,且气瓶瓶内有水滴存在,而发生氢致低应力脆性开裂,造成气瓶爆炸。
It indicates the positive pressure type air respirator gas cylinder material cannot tolerate hydrogen damage and during manufacturing the anti - corrosion quality not meet the requirement and the gas cylinder inside having some water drops to producet hydrogen and makes lower stress brittle cracks and leads to cylinder explosion.
