重油催化装置分馏塔顶循环线上一焊缝有砂眼,造成管道内汽油组分泄漏。由于该部位上游没有阀门,无法切出处理,停工损失又太大,决定进行焊接堵漏。 1.焊接前的安全措施 ①将泵的出口阀2关严(图1),使泄漏管线内
Heavy oil catalytic cracking unit on the top of the loop a trachoma trachoma, resulting in leakage of gasoline components within the pipeline. As the upstream part of the valve there is no way out of processing, downtime loss is too large, decided to weld plugging. 1. Safety precautions before welding ① Shut off the outlet valve 2 of the pump (Figure 1) so that the leakage line
