问题描述：
请教pipe在句中的意思?
A fully wrought structure is free from pipe and harmful segregation.
完好的锻造结构应无**和有害的成分偏析.
A fully wrought structure is free any open discontinuities ( porosity,shrinkage,pipe,etc.) when macroetched or viewed under a light microscope at 250X.在宏观刻蚀试验中用250X光学显微镜观察,应无明显的不连续（砂眼、缩孔、**、等）.
上文的pipe是什么意思?上面的句子是否应这样翻译?请帮我看看.
怎么没有人回答哦?
