油井管螺纹加工机床的技术引进及国产化

Import of Technology Concerning and Localization of OCTG Threading Machine

介绍了我国从国外引进管螺纹加工机床的发展历史及现状。分析了国外典型管螺纹加工机床的技术性能特点及其发展趋势,评价了国内管螺纹加工机床制造厂在研发方面取得的成果、设计制造水平及与国外的技术差距,提出了国产管螺纹加工机床在消化吸收国外先进技术方面的主要目标。

Described are the development history and current situation of manufacture of the OCTG threading machine which were originally imported from abroad. Analyzed are the technological performance characteristics and development trend of typical tube threaders overseas. Evaluated are the R ＆ D achievements as made by and the design and manufacture levels of domestic tube threader-makers. Also discussed is the technological gap between such makers and their foreign counterparts. Finally proposed are the main objectives in using foreign advanced technologies by domestic tube threader-manufacturers.
