摘　　要：以ASME SA213T91无缝铁素体合金钢管为例,通过对该材质不同规格的钢管以不同的检测设备分别进行试验比较,以期得到锅炉受热面部件(如过热器、再热器等)中钢管的表面硬度检测偏差,并通过数据统计、偏差分析,研究其偏差存在的原因,并在产品检验过程中加以指导应用。This study uses ASME SA213 T91 seamless ferritic alloy-steel tube as an example in order to obtain the surface test hardness deviation of boiler heating components(such as superheater or reheater) by testing the tubes in different sizes with distinct equipment. The study also focuses on researching the causes of the deviation by data statistics and numerical analysis in order to apply the result to product inspection.
