In this paper, the design of new economical steel grade, laboratory researches and industrial trial production of BNS line pipe in sour service are carried out. The results showed that such properties as the yield strength, tensile strength, elongation, impact properties and Vickers hardness of trial-produced steel pipe (as-hot-rolled and after normalizing treatment of 890 ℃) could meet the requirements of API 5L standard. After normalizing treatment of 890 ℃, the low temperature impact toughness of steel pipe is significantly improved and its ductile-brittle transition temperature is reduced from -10 ℃ (as-hot-rolled) to -50 ℃ (as-normalized condition) as well as its banded structure is improved and grain size of matrix is refined from grade 7(as-hot-rolled) to grade 8.5 with normalizing treatment.

文章针对BNS酸性服役管线管，设计了经济型新钢种，开展了实验室研究及工业试制。结果表明，不论是热轧态还是经890 ℃正火热处理后，试制钢管的屈服强度、抗拉强度、延伸率、冲击性能、维氏硬度等各项性能均满足API 5L标准要求。钢管经890 ℃正火热处理后，其低温冲击韧性大幅提高，韧脆转变温度从热轧态的-10 ℃降至正火态的-50 ℃，正火热处理改善了钢管的带状组织，且基体的晶粒度由热轧态的7级细化为8.5级。
