摘要:
为了完整评价API X52高频电阻焊管的质量及安全性能，采用MTS Landmark 370万能力学试验机，研究了两种表面状态下管体和焊缝的疲劳性能，并分析了焊缝组织变化及钢管表面状态对疲劳性能的影响。结果显示，X52 HFW钢管具有良好的综合力学性能，焊缝强度及冲击韧性与管体相当，但焊缝的疲劳性能低于管体，且表面质量对疲劳性能有明显的影响；钢管表面夹杂物及缺陷是促进疲劳裂纹萌生、降低疲劳寿命的主要原因，提高焊缝性能及表面质量能显著提高钢管的疲劳性能。
Abstract:
In order to evaluate the product quality and applied reliability of the X52 high frequency electric resistance welding(HFW) pipe, the fatigue properties of weld and pipe body in two surface states were studied by MTS Landmark 370 servo-hydraulic universal testing machine, and the influences of microstructure changes and surface states of weld on the fatigue properties were analyzed. The results showed that the X52 HFW pipes had good comprehensive mechanical properties, the strength and impact toughness of weld were similar to the pipe body, but the fatigue properties of weld were lower than pipe body, the surface quality had obvious effects on the fatigue properties; the surface inclusions and defects were the main reasons for enhancing fatigue crack growth and decreasing fatigue life, and improving weld performance and surface quality could significantly enhance the fatigue properties of HFW pipe.
