集輸管線用X65MS鋼級(jí)抗H₂S ERW焊管的研制

摘要: 結(jié)合抗H₂S X65MS ERW焊管的技術(shù)標(biāo)準(zhǔn)和要求，從材料研發(fā)、制管工藝及檢（化）驗(yàn)評(píng)估等方面對(duì)該ERW焊管的研制情況進(jìn)行介紹。試驗(yàn)結(jié)果表明：采用低C、低Mn、合金化設(shè)計(jì)和超潔凈化冶煉制造的抗H₂S X65MS卷板，通過(guò)ERW焊管成型和焊接工藝優(yōu)化控制，開發(fā)出的X65MS鋼級(jí)抗H₂S ERW焊管的理化性能完全滿足API標(biāo)準(zhǔn)要求，且其HIC性能滿足NACE TM 0284——2011標(biāo)準(zhǔn)要求，抗SSCC性能滿足NACE TM 0177——2005標(biāo)準(zhǔn)要求。

Abstract: Elaborated with reference of relevant product specification and requirements are the main aspects of R & D of the X65MS anti-H₂S ERW pipe，covering material development，pipe-making process and inspection/testing result evaluation，etc. Related test results lead to the conclusion as follows. Separately satisfactory to applicable API specification and the NACE TM 0284—2011/NACE TM 0177—2005-specified requirements are the physiochemical properties and the HIC/SSCC resistances of the X65MS ERW pipe as produced with anti-H₂S-corrosion X65MS steel coil made via well-designed low-C & Mn micro-alloying process and super-clean steel-melting technique， and by means of the ERW pipe forming process and welding process under optimized controls.
