国外无缝钢管生产发展的现状(二)

DEVELOPMENTS AND PRESENT STATE OF SEAMLESS STEEL PIPE PRODUCTION IN FOREIGN COUNTRIES (PAPTⅡ)

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。

Developments of steel pipe market and present state of tube billet and seamless tube production in foreign countries are described. The world, steel pipe market does not show a good situation but the the horizontal continuous casting technology for tube billets has been successfully developed. The seamless steel pipe production technology now has stepped to a new level through incorporating new type piercing mills into all kinds of rolling mills and developing shell wall thickness inspection under high temperature and multl-destructive inspection technology.
