Abstract

An accidental leak in a pressurized pipeline, for example as result of corrosion, will be accompanied by the rapid quasi-adiabatic expansion of the escaping fluid. In the case of some hydrocarbon pipelines, especially ethylene, the escaping fluid may reach temperatures as low as -104 °C. In such circumstances, a significant concern is the risk of the pipe wall temperature in contact with the escaping fluid eventually reaching the pipe material Ductile to Brittle Transition Temperature (DBTT), possibly leading to a propagating brittle fracture.
