    HP2 13Cr無縫鋼管的研制開發(fā)

    R & D of HP2 13Cr Seamless Steel Pipe

    • 摘要: 從成分設(shè)計、冶煉、徑鍛、擠壓及熱處理工藝流程等方面，詳細(xì)介紹了采用“熱擠壓+調(diào)質(zhì)熱處理”工藝生產(chǎn)HP2 13Cr無縫鋼管的方法。實物性能檢測結(jié)果表明：該工藝生產(chǎn)的HP2 13Cr無縫鋼管力學(xué)性能及金相組織控制較好，完全滿足ISO 13680:2010標(biāo)準(zhǔn)要求，在高含CO2、H2S酸性環(huán)境中均為輕度腐蝕，耐蝕性好。

       

      Abstract: Detailed here is the manufacturing method of“hot extrusion+quenching and tempering”for the HP2 13Cr seamless steel pipe，involving such process flows as chemical composition design，melting，diameter forging extrusion and heat treatment.Results from relevant physical performance detections and inspections show that the said pipe as manufactured with the above mentioned method is in possession of good mechanical properties and well-controlled metallographic structure，and in full compliance with relevant requirements as specified in ISO 13680:2010，and is capable of well serving in high-CO2and H2S-containing environment due to its slight corrosion，i.e.，good corrosion resistance.
