    Development of Oil/Gas Linepipe in L245NCS Steel for Service under Acidic Operation Conditions

    • 摘要: 為滿足在酸性服役條件下輸送油氣的要求,設(shè)計出化學(xué)成分合理的L245NCS鋼,通過對各工序特別是熱處理工序的嚴格控制,開發(fā)出滿足用戶要求的具有良好組織和力學(xué)性能、抗HIC和SSC的L245NCS鋼石油天然氣輸送用管。簡要介紹了該產(chǎn)品的化學(xué)成分和工藝設(shè)計、生產(chǎn)工藝以及檢測結(jié)果。

       

      Abstract: To satisfy the requirement for oil/gas transport under acidic operation conditions, the L245NCS steel is produced with its chemical composition well designed.With all the operation steps, particularly the heat treatment process strictly controlled, the HIC and SSC L245NCS steel oil/gas linepipes in possession of good structural and mechanical properties are developed.Briefed in the paper are the main aspects of the said linepipe, including the chemical composition, technological design, manufacturing process as well as relevant testing/inspection results.
