摘要:
为了减少长输管线对口数量,提高钢管对接环焊缝质量,对双联管的应用实例、标准要求及资质情况进行了汇总分析。通过焊接方法的对比确定内外焊均采用埋弧焊生产效率最高,且能够获得优良的焊缝质量与性能。根据钢管管端尺寸得出了以下焊接方案:管端切斜1 mm左右时可采用STT/RMD根焊的“小钝边、小间隙”对接方案;管端切斜在2~3 mm时可采用内焊侧加陶瓷衬垫的“小钝边、大间隙”对接方案;管端切斜≤0.5 mm时可采用气保焊直接打底焊的“大钝边、无间隙”对接方案。
Abstract:
In order to reduce the number of long distance pipeline butt joints and improve the quality of steel pipe butt girth welds, the application examples, standard requirements and qualification of double-pipe are summarized and analyzed. Through the comparison of welding methods, it is determined that submerged arc welding is adopted for both internal and external welding, with high production efficiency and excellent weld quality and performance. According to the size of pipe end, the following welding schemes are obtained: when the beveling length of pipe end is about 1 mm, the small blunt edge and small gap butt joint scheme of STT/RMD root welding can be adopted; when the beveling length of pipe end is 2~3 mm, the small blunt edge and large gap butt joint scheme with ceramic liner on the inner welding side can be adopted; when the pipe end cutting angle is less than 0.5 mm, the large blunt edge and no gap butt joint scheme can be directly adopted by gas shielded welding.
