Is it meaningful to install expansion bends to relieve stress in the pipelines of nitrogen systems at 0.7MPa and 4.0MPa?
There aren’t many temperature-sensitive ones, so it should not be necessary.
It should be determined based on the total length of the pipeline and the magnitude of the temperature difference
Expansion bends are generally used to absorb thermal expansion. Pressure mainly affects the selection of the tube wall thickness. If the operating temperature is not high, an expansion bend is not necessary. Even if an expansion bend is created, the stress caused by pressure will not decrease.
How long? How much of a temperature change? Needed?
If there’s no temperature change, then it’s not necessary, right?
Let’s simulate it: if the flexibility of the pipe itself is sufficient, it might not be necessary to use expansion bends.
What’s the temperature? Low-temperature pipelines below zero?
Nitrogen pipelines generally do not experience temperature changes, so expansion bends may not be necessary
