A large amount of oil-gas pipeline safety accidents from the point of view of, the inferior of welding quality is the one of the main reasons for causing oil-gas pipeline accident, because
This pipeline welding quality problems must attract great attention.
To meet the ever-increasing energy demand of China, single conduit design throughput is continuously increased, construction steel pipe
Strength grade, caliber, wall thickness and discharge pressure etc. also gradually increase, and higher requirement is proposed to site Welding Technology.China
Start to build heavy caliber long distance pipeline at the beginning of the seventies in last century, Daqing oil field has been built in famous northeast " eight or three " pipeline mass campaign
To Tieling, Tieling to Dalian, Tieling to Qinhuangdao oil pipeline, solve puzzlement Daqing crude oil outside defeated problem.The pipeline is set
The mm of caliber φ 720 are counted, steel select 16MnR, Seam of SAW Spiral Steel Pipe, 6 ~ 11mm of wall thickness.Welding procedure design is：Manual arc
Soldering method, welds operating procedure upwards；Wlding selects 400 DEG C, 1h of baking, φ 3.2mm bottoming, φ before J506, J507 welding rod, weldering
4mm fillings, capping；The source of welding current uses rotary DC arc welder；Groove is 60 ° of V-types, root one side welding with back formation.Northeast
" eight or three " join in a battle built pipeline and have run 30 years, so far still under arms, it was demonstrated that process program then is correct, and applies
Working medium amount is good.The beginning of the eighties in last century starts to promote by hand Welding downwards, while having developed cellulose type and low hydrogen
The downward welding rod of type.Compared with traditional upward Welding, downward soldering set there are the outstanding advantages such as speed is fast, quality is good, saving wlding,
Therefore it is widely used in pipeline girth welding.The beginning of the nineties in last century starts to promote self-protection flux-cored wire half certainly
