摘要:
通过对深海管线服役工况的分析,总结了深海用管线钢的技术特点,表明高强度、大壁厚、小径厚比管线钢管是深海用管线钢管的发展趋向。通过采用低C高Mn,Nb和Ti微合金化的成分设计和TMCP工艺控制,开发出了深水用X70钢级、厚壁 36.5 mm管线钢,其全壁厚组织以均匀细小的针状铁素体+少量M/A岛为主。对钢板进行了实物力学性能测试,测试结果显示:屈服强度480~550 MPa,屈强比≤0.82,-20 ℃下冲击功410 J以上,横向和纵向DWTT断口纤维率为100%,该深海管线用X70厚壁管线钢达到高强度、低屈强比、高韧性和优良低温抗动态撕裂能力的良好匹配。
Abstract:
Through analysis of deep-sea pipeline service conditions,it summarized the technical characteristics of deep-sea pipeline steel,and showed that high strength, heavy wall thickness and small diameter-thickness ratio are the development trend for deep-sea pipeline steel pipe. By using high Mn,low C and Nb,Ti micro-alloying composition design,and TMCP process,the X70 pipeline steel with 36.5 mm thickness used in deep-sea pipeline was developed. The main microstructure of full thickness consists of uniform fine acicular ferrite and a small number of M/A island. The yield strength of steel plate arrives 480~550 MPa,the yield ratio≤0.82,the impact energy over 410 J at -20 ℃,the fiber fracture rate is 100% of horizontal and vertical DWTT, which achieves good matching with high strength,low yield ratio,high toughness and excellent dynamic tear resistance at low temperature.
