有关管板厚度的取值问题

About the Tube Sheet Thickness Values Issues

管板是管壳式换热器最重要的受压元件之一,管板的合理设计对降低设备费用和保证设备安全运行是至关重要的,管板的强度计算又是管板合理设计中很关键的一步。为此,应正确理解管板名义厚度、管板有效厚度和管板最小厚度的取值问题。

Tube sheet is one of the shell and tube heat exchangers most important pressure parts ,tube plate rational design of equipment to reduce costs and ensure the safe operation of equipment is essential .Strength calculation tube plate and tube sheet is a reasonable step in the design is critical .Therefore ,we should correctly understand the value of the nominal thickness of the tube sheet problems ,the effective thickness of the tube plate and tube plate minimum thickness .
