The operating temperature is higher than the design temperature
Thread Content
The design pressure of the inlet buffer tank for the circulating exhaust fan is 0.1 MPa, the design temperature is 60°C, and the maximum operating pressure is 0.03 MPa. The operating pressure of the medium is currently 0.02 MPa, and the operating temperature is 80°C. What impact will this have on the buffer tanks? Can it be put into use?
The design pressure is much higher than the operating pressure, and the operating temperature is only 20°C higher than the design temperature. If the medium is air, I think there’s no problem and it can be used.
There’s no problem; the allowable stress of the material remains unchanged between 60 degrees and 80 degrees. The key factor is whether the internal medium will accelerate corrosion
It seems fine; that temperature range has no significant impact on the allowable stress of the material. Moreover, the design usually includes a considerable amount of margin, so there’s no problem
Your working pressure is less than 0.1, so it does not fall under the category of pressure vessels; therefore, it should be fine to use it. It would be more appropriate to ask the original design firm to issue revised specifications for the design temperature.
Although it can be used, it’s better to change the drawings...
Strictly speaking, it’s not possible; the drawings need to be changed
The internal medium contains sulfides such as sulfur dioxide and hydrogen sulfide.
What material? Ordinary metals are fine. The pressure is within the range
