摘要
对PSL2 X65Q管线用无缝钢管产品的拉伸性能、冲击性能、硬度及相关性能试验数据进行了统计和分析。分析认为:PSL2 X65Q管线用无缝钢管具有屈服强度波动范围小(≤100 MPa)、屈强比低(≤0.89)、塑性高、韧性好、硬度低、抗腐蚀性能好等特点,在满足海洋管线苛刻要求的同时,可适用于抗大变形管线和卷管施工方式管线的生产。
Conducted are statistics and analysis of experimental research data of PSL2 X65Q seamless steel linepipes as collected over the recent years, involving tensile property, impact property and hardness, etc. The result shows that the PSL2 X65Q seamless steel linepipe features small yield strength fluctuation range（≤100 MPa） , low yield ratio（≤0.89）, high plasticity, fine toughness, low hardness and satisfactory corrosion resistance, etc., being in compliance with the stringent requirements for marine pipeline, and being suitable for the anti-large deformation pipeline, and pipe-laying operation with coiling method.
