How to deal with self-cooling and tightening of pipes?
Thread Content
After the pipe expands due to heat, it undergoes plastic deformation; can the pipe still be used at this point?
Consider using heat treatment to restore mechanical properties
As long as the pipes are designed by a reputable design institute (with no overheating or overpressure during operation), there should be no problems
Plasticity occurs after thermal expansion, indicating that the material properties have changed; the setting process takes factors such as thermal expansion into account. It is recommended to replace it.
The compressive strength decreases after deformation; replace it as appropriate
After thermal expansion, the pipe undergoes plastic deformation; it can still be used as long as it does not exceed the limit values. It is covered in the pipeline design reference books
What kind of heat treatment should, or rather needs to, be carried out to restore the mechanical properties?
What kind of heat treatment should, or rather needs to, be carried out to restore the mechanical properties?
Has the design not taken thermal expansion into account, and is the wall thickness of the pipes insufficient? ? ?
It’s best to check the technical specifications; if it’s within the acceptable range, there shouldn’t be any problems. However, if the expansion coefficient is too high, it can lead to increased thermoplasticity, and in that case it’s recommended to replace it
