摘要:介绍了国内螺旋缝埋弧焊钢管的产品技术现状以及预精焊(二步法)技术在国内外的应用情况,从产
品实物性能指标、工作效率等方面对比分析了采用预精焊生产螺旋缝埋弧焊钢管的优点,并针对其存在的问题提
出了解决措施。分析认为,国内螺旋缝埋弧焊钢管的生产主要以一步法为主,但根据市场需求和油气输送管技术
发展方向,从国外引进预精焊技术并对现有工艺技术进行改造很有必要

Abstract Briefly introduced are the present domestic development situation of the product technologies for
the SAWH pipe, and the applications of the pre-welding process (the two-step process )for producing such pipes
at home and abroad. The advantages of manufacture of the SA WH pipe with the pre-welding process is comparatively
analyzed in terms of product material object performance index and work efficiency. Moreover, addressing the prob-
lems related to manufacture of the SA WH pipe with the pre-welding process, some countermeasures are proposed
Based on the analysis, it is concluded that although the one-step process is mainly employed by the domestic
SAWH pipe-making circles, it is also necessary to introduce the pre-welding process from abroad, and carry
upgrade of the currently-used process technologies in a bid to meet the market demand, and follow the develop
ment trend of the technology for oil/gas linepipe production
