摘要
大直径进口高强度管材制作弯管在国内尚属首次．为了确保产品质量．针对陕京管线用ＡＰＩＳＰＥＣ５Ｌ的Ｘ６０级，ＤＮ６５０钢管制作弯管．我们编写了相关的技术条件，规范了其材料、公差、制造、技术要求、检验和标志，从而为保证陕京输气管道工程Ｒ＝５Ｄ弯管制作质量确立了可循的依据。
At home , it is the first to fabricate bends using imported large-size and high-strength steel pipe. Shaan-Jing Gas Pipeline will censist of steel pipes ×60,Spec. 5L and bends will be fabricated using DN 650 steel pipe. In order to ensure products quality and standardize materials,tolerances. fabrication, technical requirements, inspection and marking for bends, we have compiled related technical conditions.
