- 印度东气西输天然气管道工程,管径1219mm(48in),管材钢级为API5LX70,工作压力10MPa。管道焊接技术规范是业主与美国环球咨询公司以API1104-2005标准为基础,参考ASTM、ASME等标准共同编制的。文章介绍了该管道工程焊接工艺评定的主要规定,以及自保护药芯焊丝半自动焊工艺、英国NOREAST内焊机根焊+国产PAW2000型外自动焊机填充盖面焊工艺、美国CRC内焊机根焊+CRCP260外自动焊机热焊+CRCP600双炬外焊机填充盖面焊工艺在管道施工中的应用。
In India East to West Gas Transmission Pipeline Project,the pipe diameter is 1 219 mm,the pipe steel grade is API 5L X70 and the pipeline operation pressure is 10 MPa.The pipeline welding criterion is formed together by the owner and American Universal Consulting Co.on the basis of API 1104-2005 standard and getting references from the standards such as ASTM and ASME.The main provisions of the welding process assessment for this pipeline project are presented in this paper.Also the applications of some welding processes in the pipeline construction are described including semi-automatic welding process with self-protection flux core welding wire,root welding with Britain NOREAST internal welding machine plus filling and capping welding with domestic PAW-2000 external welding machine,root welding with American CRC internal welding machine plus heating welding with CRC P262 external automatic welding machine plus filling and capping welding with CRC P600 double torches external automatic welding machine.2009,4(4): 46-48 收稿日期：2008-5-20分类号：TE973.3作者简介：靳红星(1967- ),男,河北香河人,高级工程师,1992年毕业于石油大学,天津大学材料工程硕士,长期从事长输管道焊接与施工工作.参考文献：
