以大型制冷系统中的饱和氨蒸气为工质 ,通过在高度为 40 0 0 m m的四种螺纹钢管外表面上凝结换热的试验研究 ,得到了管外凝结换热的准则关联式。试验结果表明 ,在试验条件下与光滑钢管相比较 ,螺纹钢管外表面上的平均表面传热系数是光滑钢管的 1.15~ 1.4倍。

The hot-rolled seamless steel pipes with deeper screw slots do mot meet the needs of quality standards. A high-speed magnetic flux leakage testing system for steel pipes based on computer intelligent software was developed, which could be used to detect and identify the screws inside pipes and to mark their positions and ranges. The output of qualified steel pipes could be hightened by the feedback of testing information to the rolling process. The testing speed of the system was 20-60m/min and the depth of...

The hot-rolled seamless steel pipes with deeper screw slots do mot meet the needs of quality standards. A high-speed magnetic flux leakage testing system for steel pipes based on computer intelligent software was developed, which could be used to detect and identify the screws inside pipes and to mark their positions and ranges. The output of qualified steel pipes could be hightened by the feedback of testing information to the rolling process. The testing speed of the system was 20-60m/min and the depth of screw slot detected was 0.4-2.0mm.
