该文针对用低合金高强度钢焊接而成的高压空气瓶在长期使用后存在的问题,对八只旧气瓶作了强度、断裂、寿命分析方面的试验研究,为制定在役高压气瓶检验标准提供了必要的依据。并提出声发射技术监测是在役高压气瓶安全性评定中一个有效的检测手段。
In this paper, the problem of long-term use of high-pressure air-conditioners welded with low-alloy high-strength steels has been studied in eight old cylinders for strength, fracture and life-span analysis. Inspection standards provide the necessary basis. And proposed acoustic emission monitoring technology is an in-service high-pressure gas cylinder safety assessment of an effective means of detection.
