摘要
蒸汽轮机管路用异径管在焊后做液体渗透检查时发现内部存在4条轴向分布的短裂纹,通过进一步检测和试验分析,确定了缺陷的原因来自制作管件的原材料本身,而不是在制造过程中产生的,对以后制造类似产品以及质量控制提供一定帮助。
When being penetration tested postweld, four axial distributed short cracks were found in the reducer in the pipeline for steam turbine. With further examination and analysis, it was determined that the cracks did not originate from fabricating process but from the material prepared for this fitting. The conclusion presented may be provided as reference in later quality control for the similar products.
