在化工生产中,由于腐蚀等原因,一些使用年久的设备和管道会发生穿孔泄漏现象。化工生产的连续性强,在一般情况下,不可能为一、两个穿孔泄漏处作较长时间的停车来进行动火检修,当然也不可能任其继续泄漏。否则,穿孔泄漏处会不断地扩大,有害介质大量泄漏,从而导致腐蚀加剧、环境污染、物料流失并危及安全操作,直接影响化工生产的正常进行。根据穿孔泄漏设备和管道的使用条件,如操作介质及其浓度、温度和压力等情况,
In chemical production, due to corrosion and other reasons, some used equipment and pipes will occur perforation leak. Continuous chemical production, under normal circumstances, it is impossible for one or two perforation leak for a longer period of parking for hot-work overhaul, of course, can not let it continue to leak. Otherwise, perforation will continue to expand, a large number of harmful media leaks, resulting in increased corrosion, environmental pollution, material loss and endangering the safe operation of a direct impact on the normal chemical production. According to perforation leakage equipment and piping conditions of use, such as the operating medium and its concentration, temperature and pressure conditions,
