06 钢质纯净 S ≤ 0.003%, P ≤ 0.015%, 实物质量达到纯净钢水平. 韧性优异 管体、加厚端、对焊区及公母接头冲击韧性均远高于 API 标准要求. 优化的加厚结构 加厚过渡区 MIU 长度远大于 API 标准要求,应力集中小, 疲劳寿命高. 直度严格 管体与加厚偏心度、管体与工具接头同轴度、钻杆全长 直线度均远严于 API 标准要求. 装备先进 长且平滑的内加厚过渡区 Long and smooth taper of internal upset 制造工艺特点 Manufacture process characteristics 钻杆的生产工艺十分复杂, 而从炼钢、 连铸 (模铸) 、 轧管、 管端加厚、管体热处理、工具接头制造、摩擦对焊、焊 缝热处理直至钻杆成品,全部由一个厂家完成的,国内 仅宝钢一家. The producing process of drill pipe is very complicated, and in China only Baosteel can complete the whole process from steel-making, continuous casting (die casting), tube rolling, pipe end upsetting, tube body heat treatment, tool joint manufacturing, friction welding, weld zone heat treatment till finished product of drill pipe in one manufacturer. 一体化生产 Integrated production 钻杆加厚 Upsetting of drill pipe 钻杆热处理 Heat treatment 钻杆摩擦焊 Friction welding State-of-the-art facilities Pure steel quality S≤0.003%, P≤0.015%, and the physical quality has reached pure steel level. Excellent toughness The absorbed energy of pipe body, upset end, weld zone, pin and box tool joint is far beyond the requirements of API standard. Optimized upsetting structure The MIU length of internal taper is far beyond the requirements of API standard, which provides small stress concentration and long lifetime. Strict straightness The eccentricity between the pipe body and upsetting part, the alignment between the pipe body and tool joint, and the full-length straightness of drill pipe are all far beyond the requirements of API standard.
