Abstract

Stress development in pipes due to local fluid freezing is investigated through a simple analytical model based on thin axisymmetric shell theory. Particular attention is given to modelling the interaction between the pipe wall and the ice formed within the freezing jacket. The developed analysis accounts for the interface shear traction and relies on rational assumptions regarding its distribution in order to interpret and reproduce observed pipe behaviour. It is validated by comparing its predictions to available exact and numerical solutions as well as experimental data. Finally, it proves a valuable tool in understanding the ice plug-pipe wall interaction mechanism which controls stress generation and distribution.
