摘要
列举了大量数据和实例,说明国民经济的基础性材料──管材已呈多样化。近年来,我国无缝钢管产量已处于世界前列,机组既多又新,因此发展钢管工业必须注意其产品的相互取代性以及投资的经济性。探讨了无缝钢管生产技术的发展方向以及投资改造应注意的问题。
: Based on a lot of relevant data and case analysis, it is proven that as one of the fundamental materials for national economic construction, the tubular goods has been diversified. In recent years, China has been at the front of the world seamless steel tube industries in terms of total annual production volume. Just because of this and the fact that a lot of the- state- of- art mills have been set up, further development of steel tube industry should be focused on the interchangeability of certain tubulars and economic benefit of investment. Also discussed are such issues like the development prospect of seamless steel tube manufacturing technologies and specific areas drawing special attention in investment for technical expansion.
