| Abstract: | The steam pipeline at Dalian Development Zone, which was built by No .2 Oilfield Construction Company of Liaohe Petroleum Exploration Bureau, is the pipe-in-pipe structure with steel material of Q235. This paper describes weldin g method of inner pipes and outer pipes in detail. The practice proves that this method has the advantages of reasonable welding process, high weld quality and remarkable economical benefit for welding of small diameter thin wall pipeline. |
