- 摘要:
- 茂名石化工程公司承建的聚丙烯环管反应器,其主体材料选用美国ASME标准SA6 72C70 -CL2 2《中温高压用电熔化焊钢管》,该钢管是由美国ASTM标准SA5 16 -C70《中低温压力容器用碳钢板》焊接而成,为制定合理的焊接工艺,保证焊接接头的质量及设备运行的稳定性,文章对SA5 16 -C70钢的焊接性能包括焊接冷裂纹敏感性、返修、热处理、低温韧性等进行了系统、全面的试验研究。研究结果表明,该钢种具有优良的焊接性能和接头综合性能,焊接参数对其低温性能有着重要影响。
The main materials of polypropylene loop pipe reactor constructed by Maoming Petrochemical Engineering Company use the ones as per American ASME Standards SA672C70-CL22 Electric Fusion-Welding Steel Pipe for Middle Temperature High Pressure.This steel pipe is made (welded) with the coil as per American ASTM Standards SA516-C70 Carbon Steel Plate for Middle Low Temperature Pressure Vessel. In order to work out rational welding process assure welding joint quality, the SA516-C70 steel welding properties including welding cold crack sensitivity, repair, heat treatment, low temperature toughness etc. were systematically fully tested studied by writer. The researched results show that this kind of steel has excellent welding properties synthesis joint properties and welding parameters have a very important influence to its low temperature properties.2002,6(6): 26-29,34,3 收稿日期：2002-8-3分类号：TG457作者简介：宋虎堂,高级工程师.1989年毕业于华南理工大学化机系,获工学硕士学位,现为茂名石化工程公司副经理、总工程师.长期以来一直从事石油化工设备的设计、制造及安装、使用工作.通讯地址:广东省茂名市官渡桥北西区13栋,邮编:525000参考文献：
