叙述了国外钢管市场的发展状况,介绍了管坯生产和无缝钢管生产的现状。世界钢管市场并不景气。水平连铸的管坯生产技术已经成熟。新型穿孔机的各种轧管机的组合和高温下的毛管壁厚检测、多功能无损检测技术的发展把无缝钢管生产技术推向了新的高度。
Described the development of foreign steel market, introduced the status of the production of seamless steel pipe and seamless steel pipe production. World steel market is not good. Horizontal continuous casting tube production technology has matured. The combination of various new pipe mill and the capillary wall thickness detection under high temperature, the development of multi-functional non-destructive testing technology has pushed the seamless steel tube production technology to a new height.
