油品贮运系统对管道进行检修施焊是经常遇到的问题,输油管道动火检修可根据具体情况和所具备的条件,选用不同的方法。 （1）全线吹扫动火施焊。油品罐区输油管道的某个部位需要动火施焊时,先用蒸汽吹扫干净,将与此管道相连接口处均用盲板密封隔离,然后由化验人员测量合格后方能动火焊接。 （2）锯断用井抽子法动火施焊。输油管道较长,动火部位附近又无可拆卸的法兰或阀门,连接支线较多,无法拆卸和冲洗的场合,可采用锯断用井抽子堵动火焊接法兰的方法。将需动火施焊部位,先用钢锯割断（边锯应边加润滑油）,然后实测内径制作井抽子。
Oil storage and transportation system for pipeline repair welding is often encountered problems, hot oil pipeline repair can be based on the specific circumstances and the conditions, choose different methods. (1) full range of hot wire welding. Oil tanker oil pipeline part of the need for hot work welding, first with steam purge, will be connected with this pipe are blind sealed isolation, and then tested by the laboratory personnel after the fire welding. (2) Saw cut well pumping method law welding. Oil pipeline is longer, there are no removable flanges or valves in the vicinity of the moving parts of the fire, the connecting branch line more, can not be disassembled and flushing occasions, can be used sawing well pumping blockage fire welding flange method. Will be hot-fire welding site, first cut with a hacksaw (while the saw should be side plus lubricating oil), and then measured the diameter of production wells pumping child.
