我厂2号炉安装完毕后,在煮炉时,点火油系统管路的环形焊缝出现一条长约10mm的缝隙,柴油从缝隙处往外滴漏,点火油的油压为1.8MPa,据观察渗漏有扩大的迹象。漏出的柴油渗入锅炉的保温层,随时可能造成火灾,严重威胁锅炉的安全生产。如停炉修理,则会影响锅炉的煮炉效果。 由于管道内为0号柴油,因此检修时严禁动明火,不能进行焊接,所以采用粘补的方法修理较为理想,这
After the installation of No.2 furnace in our factory, there was a gap of about 10mm in the annular weld of the ignition oil system pipeline when the furnace was boiled. The diesel dripped out from the gap and the oil pressure of the ignition oil was 1.8MPa. According to the observation of seepage There is no sign of expansion. Leakage of diesel infiltration into the boiler insulation, may cause a fire at any time, a serious threat to the safety of the boiler. Such as shutdown repair, it will affect the boiler cooking effect. Due to the No. 0 diesel oil in the pipeline, it is strictly forbidden to open the fire when overhauling, so the welding can not be carried out. Therefore, the method of sticking and repairing is more ideal
