钢管学术委员会三届四次年会对近年来国内个别人提出的焊管经张力减径即所谓“焊管无缝化”的提法及其推广造成的不良影响进行了认真讨论,从理论、工艺、技术经济等各个方面进行分析、评价,一致认为所谓“焊管无缝化”的提法在技术上是错误的、不科学的,极易造成误导。此外,在生产短管的钢管机组上采用张力减径也是不经济的。因此,有必要对此问题给予科学客观的认识,进行正确的技术、舆论导向。各专业委员会都应该认真研究各专业国内外生产、技术发展动向,帮助企业把握好生产、技术发展方向,以促进生产的健康发展。
The Fourth Annual Meeting of the Third Session of the Academic Committee of Steel Tube and Pipeline has seriously discussed the formulation of the pipe reduction by the domestic individual in recent years as the so-called “seamless pipe” and the adverse impact caused by its promotion. The theory, technology, Technical and economic aspects of all aspects of analysis, evaluation, agreed that the so-called “pipe seamless” formulation is technically wrong, unscientific, easily misleading. In addition, it is uneconomical to use strain relief on pipe units producing spools. Therefore, it is necessary to give this issue a scientific and objective understanding of the correct technology and public opinion. All professional committees should earnestly study the domestic and foreign production and technological development trends of various professions and help them grasp the production and technological development directions so as to promote the healthy development of production.
