Thread Content
Let’s discuss: What exactly is the “normal temperature” that is commonly used by pressure vessel designers? (1) 20°C (2) 25°C (3) ≤50°C Note: This topic was provided by a 30dman member; the provider should pay close attention and provide a summary or the correct answer within 24 hours.

By normal temperature, it should refer to 20°C, right?
In chemistry, normal temperature refers to 27 degrees Celsius. In the design of chemical pressure vessels, I think it means: (3) ≤ 50°C: lol; I’m not sure if this is correct
It should be (1) 20°C; generally, the average temperature throughout the year needs to be taken into account.
Room temperature is generally considered to be 20 degrees Celsius :)
Room temperature is generally considered to be 20±5℃
Should we also take regional differences into account? The conditions in the south and north are not necessarily the same; in the north, normal temperature refers to 20 degrees, right?
25 degrees, I guess. I’ve been using it this way
Room temperature is also known as normal temperature or ambient temperature, and is generally defined as 25 degrees Celsius. The normal temperature for pressure vessels is generally taken as 20 degrees Celsius, which corresponds to the temperature during spring and autumn in most areas of China, such as the temperature of circulating water (natural water temperature). For example, the design temperature of the blower is 20 degrees Celsius. In the boiler design calculations, the normal temperature is also 20 degrees Celsius.
The “normal temperature” commonly assumed by pressure vessel designers* is 20°C.
In general process engineering, the normal temperature is set at 40°C; in chemical pressure vessels, it may be set at 20°C, which provides a more conservative calculation
Less than or equal to 50 degrees Celsius, I think
What exactly is the “room temperature” commonly used by pressure vessel designers*? Answer: (1) 20℃
Room temperature refers to ‘normal temperature and pressure’, which generally means 20°C and 1 atmosphere of pressure.
Room temperature should be a range of temperatures; 20°C or 25°C is considered room temperature, so I chose ≤50°C.
Room temperature refers to the usual ambient temperature, set at 20℃
I think it should be ≤50°C, because the highest temperature throughout the year can exceed 40 degrees; 20 degrees certainly can’t be considered normal temperature. If we’re talking about average temperature, then it’s even less appropriate, as I believe that when designing pressure vessels, the most dangerous operating conditions need to be taken into account. So I think ≤50°C is a more suitable value!
