在国内,大口径X80钢级的热压三通制造技术一直缺乏系统的研究。针对西气东输二线管道工程三通,通过数值模拟分析方法获得并优化了准Ф1219mm三通成形工艺参数,为大口径热压三通挤压工艺提供理论依据。
In China, large-diameter X80 steel grade hot tee manufacturing technology has been the lack of systematic research. According to the tee of the second West-East Gas Pipeline Project, the parameters of quasi-Ф1219mm tee forming process were obtained and optimized by numerical simulation method to provide the theoretical basis for the large-caliber tee pressing process.
