在用热壁加氢反应器不锈钢堆焊层检测

Detection for SS Bead Weld of Hydrogenation Reactor with Heat Wall at Status of Working

茂石化公司已建成投产多套加氢装置,关键设备热壁加氢反应器不锈钢堆焊层的完好,对反应器的安全运行至关重要。茂石化锅炉压力容器检验所(锅检所)在检测实践中,结合JB/T4730和TSGR7001,对堆焊层在使用中的可能损伤有了较深刻的理解,确定了堆焊层的容许缺陷、合理安全标准和缺陷的处理方法,掌握了在用热壁加氢反应器不锈钢堆焊层安全可靠、经济合理的检测方法。

Many hydrogenation units have been constructed and put into operation in MMPC. Bead weld in good condition, of hydrogenation unit with heat wall as key equipment, is vital importance to safety of nmning. In practice, through criteria of JB/T4730 and TSGR7001, as- say office deeply understand the possible damage inside of bead weld in service, determine tolerance of defect, also reasonable and safe handling, and master more reliable and economical method for SS bead weld detection of hydrogenation reactor in service.
