针对在用加氢反应器定期检验的超声检测,依据加氢反应器结构和使用特点确定检测重点部位,提出不等厚焊缝中缺陷的定位修正及反应器堆焊层的剥离和堆焊层间裂纹是检测工艺实施过程中应重点关注的问题。
Aiming at the ultrasonic testing which is carried out periodically by the hydrogenation reactor and the key parts of the detection are determined according to the structure and the use characteristics of the hydrogenation reactor, the positioning correction of the defects in the unequal thickness weld and the delamination and surfacing layer of the reactor surfacing layer are proposed Crack between the detection process should be focused on the issue of implementation.
