乙烯球罐是生产乙烯装置中的重点设备之一,它是在高压低温条件下贮存易燃易爆介质。自1976年5月投料运行以来,发现较多裂纹,为此采用声发射装置进行监测。1979年开始,先后用美国D/E公司的3000系列和1032D源定位系统,对一个球罐做了背景噪音试验和衰减试验,并且进行了现场升降压的监测试验。最后,在生产检修时作了开罐验证,本文介绍试验情况。
Vinyl tank is one of the key equipment in the production of ethylene plant, it is stored under high pressure and low temperature flammable and explosive medium. Since the commissioning operation in May 1976, more cracks were found and acoustic emission devices were used for monitoring. Beginning in 1979, the background noise test and attenuation test of a spherical tank were conducted by using the American D / E 3000 series and 1032D source positioning system successively. And the monitoring test of the lifting and lowering pressure on site was carried out. Finally, when the production overhaul made a can opener verification, this article describes the test situation.
