摘要
北溪管道项目是迄今为止世界上最长的海上管道。大口径、高压力的特点要求管材必须进行严格的质量控制。介绍了北溪管道用38个大直径弯管的制造商Salzgitter Mannesmann Grobblech GmbH对制造装备的升级改造,以及弯管、弯管母管材料设计、制造工艺和质量水平。生产结果表明,各项性能指标和尺寸公差均达到标准要求。
The Nord Stream pipeline project is the longest offshore pipeline all over the world up to now.The characteristics of large diameter and high pressure require strict quality control of pipes.This paper introduces the upgrading of manufacturing equipment by Salzgitter Mannesmann Gribblech GmbH,a manufacturer of 38 large diameter bends for the Nord Stream Pipeline,as well as the material design,manufacturing process and quality level of bends and mother pipes.The production results show that all the performance indexes and dimensional tolerances meet the standard requirements.
