摘要:
为了满足高要求耐蚀管线管的需求，通过优化炼钢工艺，改善钢中夹杂物和中心偏析，合理设定厚板工艺得到均匀的针状铁素体组织，并优化UOE成型和扩径工艺，成功开发并生产了X65MS钢级Φ914 mm×19.8 mm管线管，并对研制的管线钢管进行了理化性能试验及抗HIC和SSC性能试验。试验结果显示，82 ℃时的屈服强度和抗拉强度较常温分别下降25 MPa和32 MPa，屈强比低于0.90；焊缝、熔合线冲击功＞200 J，-20 ℃管体 SA均值为99%；附加UT定位试样缺陷后测得裂纹指标满足CLR≤10%；抗HIC、SSC、SOHIC试验均合格。试验结果表明，通过良好的成分和轧制工艺设计可获得高要求X65MS耐腐蚀管线管。
Abstract:
In order to meet the needs of high demand corrosion-resistant line pipe, through optimizing steelmaking process to improve inclusion in steel and center segregation, designing reasonable thick plate process to achieve uniform acicular ferrite, and optimizing UOE forming and expanding process, X65MS Φ914 mm×19.8 mm line pipe was successfully developed, and the performance test, HIC resistance test and SCC resistance test were carried out for the developed line pipe. The results showed that at? 82 ℃ the yield strength and tensile strength respectively decreased 25 MPa and 32 MPa, compared with room temperature, the yield ratio was below 0.90, the impact energy value of weld and fusion line was higher than 200 J, the average SA value of pipe body at -20 ℃ was 99%, CLR≤10%, the HIC resistance test , the SCC resistance test, and SOHIC test were all qualified. The results indicated that the high demand X65MS corrosion resistance line pipe can be obtained through designing good composition and rolling process.
