西气东输二线管道建设工程全长近万千米,是目前全球钢级最高、管径最大、距离最长的管线,螺旋埋弧焊管设计采用X80级高强度管线钢φ1219mm×18.4mm。经过宝鸡石油钢管有限责任公司多年的研究,在制管工艺、技术等方面形成了多项新材料和新工艺方面的科研成果:
The construction of the second West-East Gas Pipeline Project is a total length of nearly 10,000 km. It is the world’s highest grade pipe with the largest diameter and the longest distance. The spiral submerged arc welded pipe is designed with φ1219mm × 18.4mm high-strength pipeline steel. After years of research by Baoji Petroleum Steel Pipe Co., Ltd., a number of scientific research achievements in the field of pipe making technology and technology have resulted in a number of new materials and new processes:
