Determine low-temperature container?
Thread Content
Operating temperature: 40 degrees below 0, design temperature: 50 degrees. Ask whether the manufacturing process or materials used are related to low-temperature containers – is it a low-temperature container?
Is the design temperature –50°C?
Looking at the material used, if it is austenitic stainless steel, then it cannot be considered a low-temperature vessel
How are the operating temperature of -40 degrees and the design temperature of 50 degrees determined? See how GB/T150.1 determines the design temperature.
If it is 40 degrees below zero, and at times the temperature is above zero, how is a low-temperature container defined?
As long as the temperature is below zero, factors related to sub-zero conditions must be taken into account.
How was the design temperature of 50 degrees and the operating temperature of -40 degrees determined by the original poster? What a difficult situation this must be for the designer
There’s an issue with the design temperature – a typo?
The minimum design temperature should be -50. Low-temperature containers are generally insulated to retain heat; if no insulation is provided, and considering the influence of ambient temperature, the maximum design temperature should be set at 50 degrees.
The operating temperature is minus 40 degrees Celsius; according to GB150, it needs to be determined whether this constitutes a low-stress condition. If not, the vessel should be designed as a low-temperature vessel
