摘要:
为了进一步提高连续管在油田现场的使用价值和经济效益,设计了一种连续管全位置自动对接焊(自动TIG焊)工艺。采用该焊接工艺对Φ38.1 mm×3.4 mm规格CT80连续管进行了管-管对接焊,并对其焊接接头的强度、塑性、硬度及疲劳寿命进行了检测。检测结果表明,采用该焊接工艺获得的连续管管-管对焊接头,其内外焊缝成形良好,具有优良的强塑性和抗弯曲变形能力,具有较高的疲劳寿命,能满足作业现场的使用要求。
Abstract:
In order to further improve the usage value and economic benefit of coiled tubing in oil field, a kind of all-position automatic butt welding process(automatic TIG welding) was designed. By using this welding technology to conduct pipe-pipe butt welding for Φ38.1 mm × 3.4 mm CT80 coiled tubing, and the strength of the welded joint, plasticity, hardness, and fatigue life were tested. Test results showed that for the coiled tubing pipe-pipe butt welding joint obtained by this welding technology, the inside and outside welds are well formed, the weld joints possess good plasticity and strong ability to resist bending deformation, can meet usage requirements in working site.
