摘要
为了研究X80钢级Φ1 219 mm×22 mm热煨弯管局部加热工艺的可行性,对X80母管管材进行了分析,采用不同加热工艺参数进行了母管直管段、过渡区和加热区热模拟试验,对比优选出了适合局部加热的工艺参数,确定了"加热温度为1 000℃,回火温度为520℃"的局部加热工艺参数,可满足CDP-S-OGP-PL-016—2014-3《油气管道工程用感应加热弯管技术规格书》的相应要求。
In order to study the feasibility of the local heating process of X80 grade Φ1 219 mm ×22 mm high steel grade hot-bending bends pipes, the raw materials of X80 steel pipe were analyzed, and the mother pipe straight section, transition zone and heating zone were carried out with different heating process parameters. At the same time, the process parameters suitable for local heating were optimized, and the local heating process parameters of heating temperature 1 000 ℃ and tempering temperature 520 ℃ were determined, which could meet the corresponding requirements of CDP-S-OGP-PL-016—2014-3 Technical specification of induction bend for oil and gas pipeline.
