Tube sheet cost issues
Thread Content
May I ask what proportion of the cost of tube sheets accounts for the manufacturing of heat exchange equipment?
This question is too general and difficult to answer.
This mainly depends on the structure of your heat exchanger. Generally, it can account for between 2/5 and 4/5, and some can reach 90%.
The diameter is large, the heat exchange tube is short, the pressure is high, the weight of the tube sheet is very heavy, the cost must be high, and the proportion is high.
Determine it based on the heat exchanger structure, including pressure level, materials, etc.
BEM1200-1.6-250-3/25-1, the temperature is below 200 degrees, the tube is 1.5mm stainless steel, and the tube plate accounts for 12.5% of the total cost. Hope it's useful to you.
This question is not specific, but the specific proportion of the tube sheet in the manufacturing cost should be considered from several aspects. The core component of the heat exchanger is the cooling component. Sometimes in order to maximize performance, we will choose cooling components with expensive materials. Then the proportion of the material cost of the tube sheet will be much smaller, and the manufacturing cost, for various structures and The processing fees for parts and shapes are different, and the quality costs such as inspection and testing fees are also different, so it is meaningless to discuss this issue because there is no answer. All costs have their weights and their numerical values. Both values are uncertain and the ratio cannot be determined. This post was lastly written by vivo1314 Edited at 2009-4-14 22:48 ]
It is difficult to calculate. Pressure, temperature, heat exchange area, heat exchange tube material, and tube plate material are all uncertain and difficult to estimate. Just do the math yourself, there aren't that many shortcuts.
What I mean is that in general, heat exchangers that are used more often
It should be important to analyze specific issues in detail.
