Can too high a flow rate in an ethylene pipeline cause the pipe to fracture brittlely?

Can too high a flow rate in an ethylene pipeline cause the pipeline to crack?
Low-temperature steel; the specific material is not clear
Low-temperature brittle fracture?? Is the material’s lower temperature limit too high for the pipeline?
The design generally selects materials based on the most severe operating conditions; excessive flow rates in ethylene pipelines result in too low operating temperatures for the pipes, which exceeds the minimum allowable temperature for the pipe material and leads to brittle fracture.
Why can a high flow rate cause the operating temperature of the pipeline to decrease?
