    Comments on Standards of Seamless Steel Structural Tubes

    • 摘要: 對比了國內(nèi)外5個結(jié)構(gòu)用無縫鋼管標準中的牌號及化學成分、力學性能、工藝試驗等技術(shù)指標,分析了國內(nèi)外標準中這些技術(shù)指標的差距,以及產(chǎn)生這種差距的原因。對于國內(nèi)外標準存在的差異,提出了修改我國結(jié)構(gòu)用無縫鋼管標準的建議,以使我國鋼管標準與國際先進標準接軌。

       

      Abstract: A comparison is made between five Chinese and foreign standards for seamless steel structural tubes in terms of technical norms i.e., steel type, chemical composition, mechanical property and technological test. Gaps concerning the said technical norms between the Chinese standards and the foreign standards and the causes therefor are analyzed. Addressing these gaps, proposals are put forward to revise the Chinese standards for seamless steel structural tubes in a bid to get it in line with advanced correspondent international standards.
