摘　　要：简要介绍了我国小直径无缝钢管生产机组的发展情况,对几种主要机型进行评述,尤其是对穿拔机组的生产工艺进行客观评价,并从钢管行业发展的角度,对小直径无缝钢管发展趋势进行分析。分析认为,未来小直径连轧管机组的建设与发展将以国产Φ114mm、Φ89mm连轧管机组为主;若产品定位在高中端、产量适中,CPE机组是一个较好的选择机型;斜轧管机组在未来的发展中会受到限制;改进型的自动轧管机组在生产中低端产品上有较强的竞争力,而穿拔机组生产的产品也将逐渐回归到冷拔产品中。Briefed in the paper is the development of the small-sized seamless steel pipe mill in China. Com- ments are made on several major types of the mill, and in particularity, an objective evaluation is made on the manufacturing process of the piercing-drawing mill line. Viewed from general development of the steel tube-making industry, the development trend of the small-sized seamless steel tube-making field is analyzed. As a result, it is concluded that, the future construction and development of the small-sized mandrel mill would focus on the home-made ~P114 mm and Ф89 mm mandrel mills; for building of high/middle-end product-aiming mills with a moderate capacity, the CPE mill would be a good choice; the rotary-rolling pipe mill would be retained in the future development; the innovated plug mill would be rather competitive for the sake of producing low/middle-end products; and the piercing-drawing mill would eventually and gradually get back to the early production mode, i.e., producing cold-drawn pipes only.
