在管壳换热器制造中胀管率公式的应用与探讨

Application and Study of Bulge Tube Rate Formula in Manufacture of shell-tube Heat-changer

结合管壳换热器的制造对现有胀管率公式进行了分析,并根据单管模型试胀实验分析了影响胀管率公式的主要因素,并在胀接概念中明确了胀接的实质,指出了胀接公式中应考虑由于金属轴向流动造成的管壁减薄量ΔS和凸台变化量ΔSW的影响。

This paper analyzes the current bulge tube rate formula, and the main factor of the bulge tube rate formula based on the single tube model trying bulge experiment and in bulge connect concept clear and definite substance that bulge connect, it indicates that it the bulge connect the formula inside should consider to take care of the wall reduces thin measure the △S and the convex set variety the influence of the △SW.
