液化石油气球罐应力腐蚀裂纹分布情况浅析

Analysis of Stress Corrosion Cracking Defect Distribution Situation for Liquefied Petroleum Gas Sphere

应力腐蚀裂纹是影响在役压力容器安全运行的一类较大缺陷,在液化石油气球罐中存在较大几率的应力腐蚀裂纹,因此有必要开展应力腐蚀裂纹的相关研究工作。本文介绍了在役液化石油气球罐应力腐蚀裂纹的检出分布情况,总结规律,并探讨TSG21-2016中的相关规定。

Stress corrosion cracking is one big defect form influencing the safe operation of pressure vessels in service and there is great rate of stress corrosion cracking in liquefied pettroleum gas sphere, therefore, it is necessary to car~. out the relevant research work about liquefied petroleum gas sphere stress corrosion cracking. In this paper, it has introduced the detection and distribution situation of stress corrosion cracking of liquefied petroleum gas sphere in service and concluded the law, besides, discussed the relevant regulations of TSG 21-2016.
